Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot diverse categorie\u00ebn schade, zoals omschreven in onderstaande tabellen.\n\nTussen deze kwetsbaarheden zitten een zestal zeer ernstige, welke door Microsoft zijn ingeschaald met een CVSS score van 9 en hoger.\nDeze kwetsbaarheden bevinden zich in diverse componenten van Windows die bereikbaar en benaderbaar zijn vanaf netwerkverbindingen, zoals http.sys, DHCP, de Kernel en TCP/IP. Door de externe bereikbaarheid en de mogelijkheden tot uitvoer van willekeurige code, is het risico op grootschalig misbruik op korte termijn aanwezig. Op dit moment wordt (nog) geen actief misbruik waargenomen en is (nog) geen publieke Proof-of-Concept (PoC) of exploit bekend, maar het NCSC verwacht deze wel op korte termijn en adviseert daarom deze updates met spoed in te zetten.\n\n```\nWindows TCP/IP: \n|----------------|------|-------------------------------------|\n| CVE-ID         | CVSS | Impact

Microsoft and Adobe didn\u2019t disappoint. In fact, they have heralded my return with the largest Patch Tuesday release ever. Thanks? Take a break from your regularly scheduled activities and let\u2019s take a look at the latest security patches from Adobe and Microsoft.

A CVSS 10 is rare; two in the same bulletin is pretty much a unicorn. Adobe says there are no active attacks, but I would expect heavy research into creating one. The update for Coldfusion is also a Priority 1, but again, no known attacks is the wild. I suspect the Reader patch will also receive a lot of attention as malicious PDFs are common in ransomware attacks. The update for Experience Manager may be large, but it\u2019s mostly just cross-site scripting (XSS) bugs.\nMicrosoft Patches for June 2026\nThis month, Microsoft released a new record 208 CVEs Windows and Windows components, Office and Office Components, Microsoft Edge (Chromium-based), Azure, .NET and Visual Studio, Github Copilot, Defender, Exchange Server, Hyper-V, Secure Boot, and BitLocker. At least, that\u2019s my count. Microsoft\u2019s tools seem to be having some issues, as they initially included a CVE from 2020 in this release. Regardless, the count is over 200, and I counted several times.\nOne of these bugs came through the ZDI program, but bugs submitted during Pwn2Own Berlin remain unpatched. If you include the Chromium and other third-party bugs, the total CVE count for June comes to a staggering 571 CVEs. 38 of these cases are rated Critical while the rest are rated Important in severity.\nI\u2019ve been counting CVEs on Patch Tuesday since 2017, and this is by far the largest monthly release in that time. The previous record was 177 set last year. It is extraordinary that Microsoft can produce so many patches in a single month, but it does raise concerns. How many of these cases were found using AI tools? How many patches were generated using AI to assist in coding or testing? What quality issues may exist in these patches? And likely most importantly, is this the new normal? The last two months were also large releases. Should sysadmins adjust their processes for prioritization and patch deployment based on this new volume of updates? Unfortunately, Microsoft is not providing those answers right now. Hopefully that changes in the future. BTW \u2013 just a note \u2013 the current number of CVEs shipped by Microsoft this year exceeds the total number of CVEs shipped in all of 2018.\nOne of the bugs patched by Microsoft this month is listed as under active exploitation and three others are listed as publicly known at the time of release. Let\u2019s take a closer look at some of the more interesting updates for this month, starting with the bug being exploited in the wild.\n-   CVE-2026-41091 - Microsoft Defender Elevation of Privilege VulnerabilitySince Microsoft doesn\u2019t provide info on how widespread exploitation is, we must read some tea leaves. For this patch, several different people were acknowledged, which indicates multiple parties say this is in the wild, meaning exploitation is likely significant. The good news is that most people won\u2019t need to take action as Defender updates itself. However, if you don\u2019t have this configured or are in an isolated environment, you\u2019ll need to update to the latest version.\n-    CVE-2026-45657 - Windows Kernel Remote Code Execution VulnerabilityThis CVSS 9.8 bug allows remote, unauthenticated attackers to execute code at SYSTEM level without user interaction. Yup \u2013 this is wormable. The problem lies in the way the kernel handles TCP/IP. This was listed as \u201cExploitation Less Likely\u201d by Microsoft, but rest assured that every researcher and bug shop on the planet is reversing this patch right now trying to create an exploit. Test and deploy this patch quickly.\n-    CVE-2026-47291 - HTTP.sys Remote Code Execution VulnerabilityOur second CVSS 9.8 bug of the month, this also allows remote, unauthenticated attackers to execute code on affected systems without user interaction. However, there is a caveat. Systems using the default MaxRequestBytes registry value used by the Windows HTTP stack are not affected by this bug. You can edit your registry settings if you need protection while you test and deploy the patch. The bulletin includes instructions and even a PowerShell script for doing this action. Microsoft lists this as \u201cExploitation more likely\u201d, so I would definitely check your registry settings.\n-    CVE-2026-44815 - DHCP Client Service Remote Code Execution VulnerabilityHere\u2019s another CVSS 9.8 that has an odd incongruity. Although the CVSS says no permissions are required for exploitation, the write-up states it must be an \u201cauthenticated\u201d user. I would err on the side of caution here and believe the CVSS. If that\u2019s correct, then we have another bug where a remote, unauthenticated attacker could execute code on affected systems without user interaction. And since the DHCP client is on every OS, it\u2019s a juicy target. This is another one to test and deploy with haste.\n-    CVE-2026-45585/CVE-2026-50507 - Windows BitLocker Security Feature Bypass VulnerabilityIf you\u2019ve followed the ongoing saga of Nightmare Eclipse vs. MSRC, the bugs should look familiar. One is definitely a fix for \u201cYellowKey\u201d, while the other appears to be a fix for \u201cGreenPlasma\u201d. The researcher has promised a \u201cbone shattering\u201d drop on June 14, so let\u2019s hope Microsoft is able to reach some understanding with the researcher before more 0-days are released. Also, there is a script provided by Microsoft as a mitigation, but the better strategy is to test and deploy the updates.\n Here\u2019s the full list of CVEs released by Microsoft for June

\n\n\n\n\n  \n* Indicates this CVE had been released by a third party and is now being included in Microsoft releases.\n\u2020 Indicates further administrative actions are required to fully address the vulnerability.\n \nLooking at the other Critical-rated bugs in this release, the scariest-looking one is actually nothing to concern yourself with at all. The CVSS 10 bug in Azure HorizonDB has already been addressed by Microsoft and is just being documented now. That\u2019s also the case for five others. Of course, there wouldn\u2019t be a release without Office bugs that have the Preview Pane as an attack vector. There are multiple in June. There\u2019s a handful of bugs in the Remote Desktop Client, but these rely on connecting to a malicious RDP server. There are three patches for Hyper-V that allow for guest-to-host code execution. The bug in Active Directory requires authentication, but any authenticated user can hit it. For the Windows Directory Service vulnerability, it needs to be listening for TFTP. You have blocked that everywhere, right? The bug in Azure Network Adapter is somewhat unique as you need to update your Linux kernel to be protected. The bug in Azure Kubernetes allows an attacker to break out of a container and gain control of the AKS worker node. Finally, the bug in the Kerberos Key Distribution Center (KDC) seems unlikely, but if exploited, it could allow authenticated attackers to get code execution on affected systems.\nMoving on to the other code execution bugs, there are the ubiquitous open-an-own bugs in Office components like Excel and Word. The code injection bug in Exchange Server looks troubling, but it requires a machine-in-the-middle (MiTM), so exploitation is unlikely. The bugs in SharePoint require authentication, but you should note that the patch applies to both SharePoint Server 2016 and SharePoint Enterprise Server 2016. The two bugs in UPnP are interesting. Both can lead to code execution by causing an error during the handling of specially crafted data, which could lead to a Use After Free (UAF) bug. The bugs in RDP Client all require connecting to a malicious RDP server, but it\u2019s not clear why some are rated Critical and some are rated Important. The NTFS vulnerability requires a user to mount a virtual hard drive on an affected system. The last RCE bug this month is in Azure Stack Edge and requires the attacker to send a specially crafted file upload request that includes a manipulated file name or path, leading to code execution.\nThere are more than 60 Elevation of Privilege (EoP) bugs in this month\u2019s release, and as usual, most simply lead to local attackers executing their code at SYSTEM-level privileges or administrative privileges, so there\u2019s not much to add without further technical details about the bugs themselves. A notable exception is in Exchange Server, where a user on Outlook Web Access (OWA) could gain access to other mailboxes. The bug in Visual Studio Code could allow attackers to gain permissions associated with the MCP Server\u2019s managed identity. The bugs in Windows SDK and Windows UI Automation Manager could let attacker go from low integrity up to medium integrity code execution. The bug in Bluetooth just allows \u201celevated\u201d privileges without really describing what elevated might be. \nMoving on to the more than 20 security feature bypass (SFB) bugs in the June release, there are a total of 10 that impact Secure Boot. All carry scope change (S:C) in the CVSS, meaning successful exploitation affects security boundaries beyond the vulnerable component itself \u2014 specifically the ability to load untrusted code at boot, bypass Virtual Secure Mode, and undermine boot integrity guarantees. CVE-2026-45654 explicitly calls out VSM exposure. The bulk of these are credited to Alon Leviev (STORM), which is notable given his prior BootKitty/BlackLotus-adjacent research. The bugs in the Windows Boot Manager have a similar impact as the Secure Boot bugs. The UEFI Secure Boot vulnerabilities go a layer deeper. They require either local admin or physical access but could allow for the running of untrusted code even before the OS loads. Rootkits anyone? The four bugs in BitLocker all require physical access but could yield encrypted data if exploited. The bug in Windows Administration Protection allows attackers to bypass the feature that prevents standard-user apps from performing admin-level actions. The bug in Visual Studio Copilot Chat could be the most interesting non-boot bug here as it allows authentication impersonation. Mark of the Web (MotW) and Excel vulns could bypass user warnings. Lastly, the bug in PC Manager bypasses expected user controls. \nTurning our attention to the mass of spoofing bugs in the release, we instantly see 18 impacting SharePoint Server. Fortunately, these are simply cross-site scripting (XSS) bugs. It\u2019s the Exchange bugs we should really watch for. One is an XSS that an attacker can exploit by convincing an Exchange administrator to open a malicious link or message, which then runs code in the admin's web session. That's a meaningful privilege escalation path. Another is listed as an SSRF-based attack, but no other details are available. The last is a lower-impact XSS with limited confidentiality/integrity loss. The bug in Bing Search (remember Bing?) is a classic search result spoofing. The bug in Azure Stack Edge is interesting as it could allow access to resources outside the vulnerable component's security boundary. The bug in Office for Android requires user interaction. The Office Project Server bug is an authenticated XSS with low impact. The final spoofing bug is in Azure Attestation but has already been addressed. You should still verify you are protected by following the instructions in the write-up from Microsoft.\nThere are 30 different information disclosure bugs in this release, and fortunately, the vast majority of these simply result in info leaks consisting of unspecified memory contents or memory addresses. The two bugs in Visual Studio require user interaction and could \u201cdisclose information over a network.\u201d How obtuse. The bug in GitHub Copilot and Visual Studio Code could disclose discloses a sign-in access token for a user's work account. That's a meaningful credential exposure, not just random memory. That leaves the two bugs in Exchange Server. One could allow an authenticated user to gain information about which network services that the Exchange server can reach. The other sounds much like the spoofing bug in OWA as it allows attackers to see information in mailboxes they should not have access to.\nI\u2019ve never been a fan of the \u201ctampering\u201d category, as it could mean so many different things. For example, the bug in .NET simply says it could allow an unauthorized attacker to perform tampering locally. Similarly, the bug in Visual Studio says the same, expect here the tampering occurs over a network. Microsoft doesn\u2019t even bother with a CWE for the tampering bug in the DHCP Server, so your guess is as good as mine.\nThere are seven DoS bugs in the June release, and as usual, Microsoft provides little to no actionable information about the vulnerabilities. The most interesting is the bug in HTTP.sys, which is listed as publicly known. This is an uncontrolled resource consumption, rated \"Exploitation More Likely,\" and publicly disclosed. Since, HTTP.sys sits at the core of IIS and Windows web services, a network-accessible DoS here can take down any Windows server running HTTP-based services. Based on the Acknowledgement, it looks like this bug may have been found using AI. There are no real details for the other bugs, but based simply on the impact, I would focus on the Kerberos and TCP/IP bugs if you had to prioritize.\nNo new advisories are being released this month.\nLooking Ahead\nThe next Patch Tuesday will be on July 14 and will be the last one before Black Hat/DEFCON. It\u2019s usually a big release, so strap in and hang on. I\u2019ll be back then to give you my full thoughts. Until then, stay safe, happy patching, and may all your reboots be smooth and clean!\n ", "creation_timestamp": "2026-06-09T16:12:18.000000Z"}, {"uuid": "ad3265f8-d8cd-412f-a5b6-e5cf8da41894", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-47291", "type": "seen", "source": "https://infosec.exchange/users/vuldb/statuses/116723710293796398", "content": "A lot of offensive activities were identified targeting Microsoft Windows (CVE-2026-47291) https://vuldb.com/vuln/369746/cti", "creation_timestamp": "2026-06-10T03:34:34.739221Z"}, {"uuid": "05df86c3-da2a-4d86-b250-91d30daaa71f", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2026-47291", "type": "seen", "source": "https://www.ncsc.nl/alerts/microsoft-verhelpt-6-ernstige-kwetsbaarheden-in-windows", "content": "", "creation_timestamp": "2026-06-10T00:41:53.000000Z"}, {"uuid": "1be83a2c-0a5c-4543-833f-11feed9233ea", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2026-47291", "type": "seen", "source": "https://www.cert.dk/news/2026-06-10/Patch-Tuesday-i-overdrive-206-CVEer-peger-paa-et-nyt-normalniveau", "content": "", "creation_timestamp": "2026-06-10T01:30:14.000000Z"}, {"uuid": "e4e9099f-3c39-47e3-bf29-e6519c7063fc", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2026-47291", "type": "seen", "source": "https://www.cert.se/2026/06/patchtisdag-juni-2026-samlad-information-om-manadens-sakerhetsuppdateringar.html", "content": "", "creation_timestamp": "2026-06-10T05:00:00.000000Z"}, {"uuid": "cf2466af-b80d-4612-bfed-983f672d0978", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-47291", "type": "seen", "source": "https://bsky.app/profile/cyberhub.blog/post/3mnxpviddln2h", "content": "\ud83d\udccc CVE-2026-47291 - Integer overflow or wraparound in Windows HTTP.sys allows an unauthorized attacker to execute code over a network. https://www.cyberhub.blog/cves/CVE-2026-47291", "creation_timestamp": "2026-06-10T22:07:08.055058Z"}, {"uuid": "be589ba3-87c9-469a-8247-4cee04a06256", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-47291", "type": "seen", "source": "https://bsky.app/profile/securitylab-jp.bsky.social/post/3mnxwfaylc22s", "content": "Microsoft\u30012026\u5e746\u6708\u5b9a\u4f8b\u30d1\u30c3\u30c1\u3067\u53f2\u4e0a\u6700\u591a206\u4ef6\u306e\u8106\u5f31\u6027\u3092\u4fee\u6b63-3\u4ef6\u306e\u30bc\u30ed\u30c7\u30a4\u3084\u5371\u967a\u306a\u8106\u5f31\u6027\u542b\u3080(CVE-2026-50507,CVE-2026-45586,CVE-2026-47291,CVE-2026-49160)\n\nrocket-boys.co.jp/security-mea...\n\n#\u30bb\u30ad\u30e5\u30ea\u30c6\u30a3\u5bfe\u7b56Lab #security #securitynews", "creation_timestamp": "2026-06-11T00:03:23.905892Z"}, {"uuid": "35a0a316-5a12-4b8b-99f8-fdb9885e5325", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-47291", "type": "seen", "source": "https://bsky.app/profile/lasenal.bsky.social/post/3mogoxgx6lk2p", "content": "Microsoft parchea 206 fallos: r\u00e9cord de Patch Tuesday con 3 zero-days\n\nEl update de junio trae 39 parches cr\u00edticos.

Successful exploitation of this vulnerability can result in a denial-of-service condition, or, in the worst case, code execution with kernel privileges. The following is a portion of their write-up covering CVE-2026-47291, with a few minimal modifications.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n  \n  \n\n\n\n\n\n\n\n\n  \nA remote code execution vulnerability exists in the HTTP Protocol Stack for Microsoft Internet Information Services implemented in HTTP.sys. The vulnerability is due to invalid validating incoming HTTP requests. \nA remote, unauthenticated attacker can exploit this vulnerability by sending crafted HTTP packets to the target system. Successful exploitation of this vulnerability can result in a denial-of-service condition, or, in the worst case, code execution with kernel privileges.\nThe Vulnerability\nHTTP.sys is the kernel-mode HTTP protocol driver in Microsoft Windows. It provides HTTP request parsing, response caching, and SSL/TLS termination for Internet Information Services (IIS) and other applications that register URL prefixes. The driver listens on configured TCP ports (commonly 80 for HTTP and 443 for HTTPS) and processes inbound HTTP/1.x and HTTP/2 requests at the kernel level.\nWhen operating over HTTPS, HTTP.sys delegates TLS processing to the Windows Secure Channel (SChannel) provider. Inbound TCP data is decrypted on a per-record basis: each TLS record constitutes an independent unit of encryption and is decrypted separately by SChannel before being delivered to HTTP.sys as a distinct plaintext buffer. A single TLS 1.3 application data record has the following structure:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n  \n  \n\n\n\n\n  \n\n\n  \n  \n    \n    \n      \n        \n        \n        \n        \n          \n        \n        \n        \n      \n    \n  \n  \n\n\n\n\n\n\n  \nThe decrypted payload of each TLS record is delivered independently to the HTTP parser via\nUlHttpBufferReceiveEvent(), regardless of how many TLS records the underlying TCP connection coalesces into a single TCP segment. This behavior is distinct from plaintext HTTP connections, where the Windows TCP stack coalesces multiple segments into a single receive indication before the data reaches HTTP.sys.\nThe HTTP parser maintains a per-request state object that includes a dynamically grown buffer reference array. The capacity field stores the current number of allocated slots in the buffer reference array. The count field stores the number of slots currently in use. The ref_array_ptr field points to the dynamically allocated array of 8-byte buffer reference entries.\nAn integer overflow vulnerability exists in HTTP.sys. The vulnerability is due to insufficient bounds checking when growing a buffer reference array during HTTP/1.x header parsing. When HTTP.sys receives data for an HTTP/1.x request, it allocates a UL_REQUEST_BUFFER structure for each receive indication and tracks these buffers in the per-request reference array described above. The count field records the number of active buffer references, and the capacity field records the total number of allocated slots. \nAs the HTTP parser (UlpParseNextRequest()) processes header lines, it calls an inline buffer reference routine each time a new receive buffer is consumed. When count reaches capacity, the routine grows the array by reallocating it with five additional slots. The new allocation size is computed as 0x28 + capacity * 8, the contents of the existing array are copied via memmove using count * 8 as the copy length, and capacity is incremented by 5 as a 16-bit unsigned integer addition. No overflow check is performed on this addition.\nAfter 13,107 growth events, capacity reaches 0xFFFB. The next growth adds 5, producing 0x10000, which truncates to 0x0000 in the 16-bit field. On the subsequent buffer reference addition, count (which is now 65,536 or greater) exceeds the zero capacity, triggering another growth. The allocation size computation 0x28 + 0 * 8 produces a 40-byte allocation, but the memmove copies count * 8 bytes (approximately 524,256 bytes) from the old buffer into the 40-byte allocation. This results in a kernel pool heap buffer overflow of over 500 kilobytes.\nEach buffer reference corresponds to one receive buffer delivered to the HTTP parser. For plaintext HTTP connections, the Windows TCP stack coalesces received segments into large indications, and UlpMergeBuffers() further combines buffers within HTTP.sys. Over TLS connections, each TLS record is decrypted independently by SChannel and delivered as a separate buffer through UlHttpBufferReceiveEvent() into UlpCopyIndicatedData(). If each TLS record contains exactly one complete header line (terminated by CRLF), the HTTP parser fully consumes the buffer without setting the partial-parse flag, causing UlpAdjustBuffers() to advance to the next buffer via its non-merge path. This creates a 1:1 correspondence between TLS records sent and buffer references accumulated.\nTo trigger the overflow, an attacker crafts an HTTP request in which each header line is encapsulated in a separate TLS application data record. Given a minimum header line size of approximately 4 bytes and a required count of 65,536 buffer references, the total request size comes to roughly 262,144 bytes. The MaxRequestBytes registry value (at HKLM\\SYSTEM\\CurrentControlSet\\Services\\HTTP\\Parameters) must be configured to a value of at least 262,144 bytes for the server to accept a request of this size. The default value of 16,384 bytes limits the request to approximately 4000 header lines, which is insufficient to trigger the overflow. As a mitigation, keeping MaxRequestBytes at or below 65,535 bytes represents the most conservative configuration to prevent this attack.\nA remote unauthenticated attacker could exploit this vulnerability by sending a specially crafted HTTP/1.x request over a TLS connection to an affected server. Successful exploitation results in unexpected system termination due to a memory access exception in the context of the kernel. Under specific memory layout conditions, exploitation could result in arbitrary code execution in the context of the kernel.\nNotes:\n\u2022 The vulnerability is only reachable through HTTP/1.x header parsing over TLS connections. HTTP/2 and HTTP/3 use different parser paths that do not interact with the buffer reference array.\n\u2022 Body data parsing (Content-Length or chunked transfer encoding) does not add entries to the buffer reference array. Only header parsing triggers buffer reference growth.\n\u2022 At a sending rate of 10 milliseconds per TLS record, the overflow requires approximately 11 minutes to trigger.\nSource Code Walkthrough\nThe following code snippet was taken from HTTP.sys version 10.0.26100.7705. Comments added by TrendAI Research have been highlighted.\nIn UlpParseNextRequest():\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n  \n  \n\n\n\n\n  \n\n\n  \n  \n    \n    \n      \n        \n        \n        \n        \n          \n        \n        \n        \n      \n    \n  \n  \n\n\n\n\n\n\n  \nDetection Guidance\nTo detect an attack exploiting this vulnerability, the detection device must monitor and parse traffic on the TCP port 443.\nThe traffic on the affected port(s) is TLS-encrypted. The detection device must be able to decrypt the TLS traffic before applying the following detection method. The detection device should monitor for HTTPS connections.\nAn HTTP/1.x request [1] consists of a request line followed by zero or more header field lines, each terminated by CRLF. The following grammar defines the relevant structure:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n  \n  \n\n\n\n\n  \n\n\n  \n  \n    \n    \n      \n        \n        \n        \n        \n          \n        \n        \n        \n      \n    \n  \n  \n\n\n\n\n\n\n  \nDecrypted traffic inspection:\nAfter decrypting the TLS session, the detection device must parse the HTTP/1.x request headers. The detection device must count the number of distinct header field lines present in a single HTTP request. If the number of header field lines in a single request exceeds 1,000, the traffic should be considered suspicious; an attack exploiting this vulnerability is likely underway.\nEncrypted traffic heuristics:\nWhere decryption is not available, the detection device should inspect the pattern of TLS application data records within the encrypted session. If each TLS application data record contains a single short payload and the total number of such records on a single connection exceeds 1,000, the traffic should be considered suspicious; an attack exploiting this vulnerability is likely underway.\nNotes:\n\u2022 The preferred detection method (header line count) requires the ability to decrypt TLS traffic, for example through TLS inspection, a decrypting proxy, or possession of the server's private key. This method directly observes the attack indicator and produces low false-positive and false-negative rates.\n\u2022 The TLS record heuristic operates on encrypted traffic and does not require decryption. This method is more prone to false positives (legitimate applications that send many small TLS records, such as interactive streaming sessions, may trigger the heuristic) and to false negatives (the threshold is based on observable record sizes rather than the actual header count that determines exploitability). Where possible, decrypted traffic inspection should be preferred.\n\u2022 The attack requires approximately 11 minutes of sustained connection to accumulate sufficient header lines. Connection duration monitoring may serve as a supplementary detection heuristic.\nConclusion\nThis vulnerability was patched by Microsoft in the June 2026 release cycle. They note several mitigations that include editing the registry to ensure unpatched systems are not vulnerable to exploitation. However, the best method to ensure this bug has been fully remediated is to test and deploy the vendor-supplied patch.\nSpecial thanks to Yazhi Wang and Jonathan Lein of the TrendAI Research team for providing such a thorough analysis of this vulnerability.

It provides HTTP request parsing, response caching, and SSL/TLS termination for Internet Information Services (IIS) and other applications that register URL prefixes. The driver listens on configured TCP ports (commonly 80 for HTTP and 443 for HTTPS) and processes inbound HTTP/1.x and HTTP/2 requests at the kernel level.\nWhen operating over HTTPS, HTTP.sys delegates TLS processing to the Windows Secure Channel (SChannel) provider. Inbound TCP data is decrypted on a per-record basis: each TLS record constitutes an independent unit of encryption and is decrypted separately by SChannel before being delivered to HTTP.sys as a distinct plaintext buffer. A single TLS 1.3 application data record has the following structure:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n  \n  \n\n\n\n\n  \n\n\n  \n  \n    \n    \n      \n        \n        \n        \n        \n          \n        \n        \n        \n      \n    \n  \n  \n\n\n\n\n\n\n  \nThe decrypted payload of each TLS record is delivered independently to the HTTP parser via\nUlHttpBufferReceiveEvent(), regardless of how many TLS records the underlying TCP connection coalesces into a single TCP segment. This behavior is distinct from plaintext HTTP connections, where the Windows TCP stack coalesces multiple segments into a single receive indication before the data reaches HTTP.sys.\nThe HTTP parser maintains a per-request state object that includes a dynamically grown buffer reference array. The capacity field stores the current number of allocated slots in the buffer reference array. The count field stores the number of slots currently in use. The ref_array_ptr field points to the dynamically allocated array of 8-byte buffer reference entries.\nAn integer overflow vulnerability exists in HTTP.sys. The vulnerability is due to insufficient bounds checking when growing a buffer reference array during HTTP/1.x header parsing. When HTTP.sys receives data for an HTTP/1.x request, it allocates a UL_REQUEST_BUFFER structure for each receive indication and tracks these buffers in the per-request reference array described above. The count field records the number of active buffer references, and the capacity field records the total number of allocated slots. \nAs the HTTP parser (UlpParseNextRequest()) processes header lines, it calls an inline buffer reference routine each time a new receive buffer is consumed. When count reaches capacity, the routine grows the array by reallocating it with five additional slots. The new allocation size is computed as 0x28 + capacity * 8, the contents of the existing array are copied via memmove using count * 8 as the copy length, and capacity is incremented by 5 as a 16-bit unsigned integer addition. No overflow check is performed on this addition.\nAfter 13,107 growth events, capacity reaches 0xFFFB. The next growth adds 5, producing 0x10000, which truncates to 0x0000 in the 16-bit field. On the subsequent buffer reference addition, count (which is now 65,536 or greater) exceeds the zero capacity, triggering another growth. The allocation size computation 0x28 + 0 * 8 produces a 40-byte allocation, but the memmove copies count * 8 bytes (approximately 524,256 bytes) from the old buffer into the 40-byte allocation. This results in a kernel pool heap buffer overflow of over 500 kilobytes.\nEach buffer reference corresponds to one receive buffer delivered to the HTTP parser. For plaintext HTTP connections, the Windows TCP stack coalesces received segments into large indications, and UlpMergeBuffers() further combines buffers within HTTP.sys. Over TLS connections, each TLS record is decrypted independently by SChannel and delivered as a separate buffer through UlHttpBufferReceiveEvent() into UlpCopyIndicatedData(). If each TLS record contains exactly one complete header line (terminated by CRLF), the HTTP parser fully consumes the buffer without setting the partial-parse flag, causing UlpAdjustBuffers() to advance to the next buffer via its non-merge path. This creates a 1:1 correspondence between TLS records sent and buffer references accumulated.\nTo trigger the overflow, an attacker crafts an HTTP request in which each header line is encapsulated in a separate TLS application data record. Given a minimum header line size of approximately 4 bytes and a required count of 65,536 buffer references, the total request size comes to roughly 262,144 bytes. The MaxRequestBytes registry value (at HKLM\\SYSTEM\\CurrentControlSet\\Services\\HTTP\\Parameters) must be configured to a value of at least 262,144 bytes for the server to accept a request of this size. The default value of 16,384 bytes limits the request to approximately 4000 header lines, which is insufficient to trigger the overflow. As a mitigation, keeping MaxRequestBytes at or below 65,535 bytes represents the most conservative configuration to prevent this attack.\nA remote unauthenticated attacker could exploit this vulnerability by sending a specially crafted HTTP/1.x request over a TLS connection to an affected server. Successful exploitation results in unexpected system termination due to a memory access exception in the context of the kernel. Under specific memory layout conditions, exploitation could result in arbitrary code execution in the context of the kernel.\nNotes:\n\u2022 The vulnerability is only reachable through HTTP/1.x header parsing over TLS connections.

Comments added by TrendAI Research have been highlighted.\nIn UlpParseNextRequest():\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n  \n  \n\n\n\n\n  \n\n\n  \n  \n    \n    \n      \n        \n        \n        \n        \n          \n        \n        \n        \n      \n    \n  \n  \n\n\n\n\n\n\n  \nDetection Guidance\nTo detect an attack exploiting this vulnerability, the detection device must monitor and parse traffic on the TCP port 443.\nThe traffic on the affected port(s) is TLS-encrypted. The detection device must be able to decrypt the TLS traffic before applying the following detection method. The detection device should monitor for HTTPS connections.\nAn HTTP/1.x request [1] consists of a request line followed by zero or more header field lines, each terminated by CRLF. The following grammar defines the relevant structure:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n  \n  \n\n\n\n\n  \n\n\n  \n  \n    \n    \n      \n        \n        \n        \n        \n          \n        \n        \n        \n      \n    \n  \n  \n\n\n\n\n\n\n  \nDecrypted traffic inspection:\nAfter decrypting the TLS session, the detection device must parse the HTTP/1.x request headers. The detection device must count the number of distinct header field lines present in a single HTTP request. If the number of header field lines in a single request exceeds 1,000, the traffic should be considered suspicious; an attack exploiting this vulnerability is likely underway.\nEncrypted traffic heuristics:\nWhere decryption is not available, the detection device should inspect the pattern of TLS application data records within the encrypted session. If each TLS application data record contains a single short payload and the total number of such records on a single connection exceeds 1,000, the traffic should be considered suspicious; an attack exploiting this vulnerability is likely underway.\nNotes:\n\u2022 The preferred detection method (header line count) requires the ability to decrypt TLS traffic, for example through TLS inspection, a decrypting proxy, or possession of the server's private key. This method directly observes the attack indicator and produces low false-positive and false-negative rates.\n\u2022 The TLS record heuristic operates on encrypted traffic and does not require decryption. This method is more prone to false positives (legitimate applications that send many small TLS records, such as interactive streaming sessions, may trigger the heuristic) and to false negatives (the threshold is based on observable record sizes rather than the actual header count that determines exploitability). Where possible, decrypted traffic inspection should be preferred.\n\u2022 The attack requires approximately 11 minutes of sustained connection to accumulate sufficient header lines. Connection duration monitoring may serve as a supplementary detection heuristic.\nConclusion\nThis vulnerability was patched by Microsoft in the June 2026 release cycle. They note several mitigations that include editing the registry to ensure unpatched systems are not vulnerable to exploitation. However, the best method to ensure this bug has been fully remediated is to test and deploy the vendor-supplied patch.\nSpecial thanks to Yazhi Wang and Jonathan Lein of the TrendAI Research team for providing such a thorough analysis of this vulnerability.
