},
{
"category": "description",
"text": "De kwetsbaarheden betreffen verschillende modules en functionaliteiten binnen Apache HTTP Server. De meest ernstige kwetsbaarheid betreft een double free in de HTTP/2-implementatie, die het voor een aanvaller mogelijk maakt om willekeurige code uit te voeren voorafgaand aan authenticatie. \n\nLokale .htaccess auteurs kunnen via een privilege-escalatie toegang krijgen tot bestanden met httpd-gebruikersrechten. Het mod_proxy_ajp module bevat een heap-based buffer overflow en een out-of-bounds read, waardoor geheugenbeschadiging kan optreden. In de mod_md module is een resource allocatieprobleem aanwezig dat de serverprestaties kan be\u00efnvloeden. De mod_dav_lock module bevat een NULL pointer dereference die kan leiden tot servercrashes en daarmee denial of service. De mod_auth_digest module kent een timing attack die Digest authenticatie kan omzeilen. De mod_authn_socache module heeft een NULL pointer dereference die crashes veroorzaakt bij caching forward proxy configuraties. Verder is er een HTTP response splitting kwetsbaarheid die manipulatie van HTTP headers mogelijk maakt. Daarnaast is er een improper null termination en out-of-bounds read in de core server functionaliteit, en een buffer over-read die kan leiden tot informatielekken of instabiliteit.",

A flaw was found in Apache HTTP Server. This escalation of privilege vulnerability allows local attackers, specifically those with the ability to author .htaccess files, to read sensitive files. This flaw enables unauthorized access to files with the privileges of the httpd user, potentially leading to information disclosure.

A flaw was found in the mod_proxy_ajp module of httpd. When processing AJP (Apache JServ Protocol) messages, the server fails to properly check if a string is null-terminated before attempting to read it, allowing an attacker or a malformed request to cause a heap-based buffer over-read. This issue potentially leads to memory disclosure and a denial of service.

A flaw was found in the mod_proxy_ajp module of httpd. When processing AJP (Apache JServ Protocol) messages, the ajp_parse_data function attempts to read data beyond the allocated buffer size, allowing an attacker or a malformed request to cause a heap-based buffer over-read. This issue potentially leads to memory disclosure and a denial of service.

A double free condition can corrupt the heap allocator\u2019s internal metadata, enabling attackers to manipulate memory layout and potentially achieve arbitrary code execution (RCE) under favorable conditions. In this case, the flaw is triggered during an early stream reset in HTTP/2, meaning it can be exercised pre-authentication by a remote client without requiring complex application-level interaction. Given that Apache HTTP Server is widely deployed in internet-facing environments, even a low-probability RCE path significantly elevates risk.\n\n\n\nAdditionally, the vulnerability exists in a core protocol module rather than an optional edge feature, increasing the likelihood of exposure. It is also important to note that this vulnerability specifically affects Apache HTTP Server version 2.4.66 only, and our mod_http2 packages are not affected as they are built against non-vulnerable httpd versions.",
