However, this level is similar to what we saw in the first quarter of last year,\u201d Dustin Childs, researcher at Trend Micro\u2019s Zero Day Initiative, said in a blog\u00a0breaking down the fixes.\nSee Also: Complete Offensive Security and Ethical Hacking Course\nhttps://www.blackhatethicalhacking.com/wp-content/uploads/2022/03/Solutions-1.png Zero-Day PatchesThe vulnerability that\u2019s been exploited in the wild ahead of patching allows privilege escalation, and is tracked as CVE-2022-24521. It rates 7.8 out of 10 on the CVSS vulnerability-severity scale. It\u2019s listed as a \u201cWindows Common Log File System Driver Execution Vulnerability,\u201d and was reported to Microsoft by the National Security Agency.\n\n\u201cIt\u2019s not stated how widely the exploit is being used in the wild, but it\u2019s likely still targeted at this point and not broadly available,\u201d Childs noted. \u201cGo patch your systems before that situation changes.\u201d\n\nResearchers noted that attackers are likely pairing it with a separate code-execution bug in their campaigns. For that reason, Immersive Labs\u2019 Kevin Breen, director of cyber-threat research, places the actively exploited bug at the top of the priority list for patching.\n\n\u201cBeing the type of vulnerability for escalating privileges, this would indicate a threat actor is currently using it to aid lateral movement to capitalize on a pre-existing foothold,\u201d he explained.\n\nThe second zero-day is found in the Windows User Profile Service, and is tracked as CVE-2022-26904.\n\nIt also allows privilege escalation, and rates a CVSS score of 7. Even though it\u2019s listed as exploitation more likely, it has a high attack complexity, Microsoft noted in its advisory, because \u201csuccessful exploitation of this vulnerability requires an attacker to win a race condition.\u201d\n\nEven so, researchers at Tripwire noted that exploit code is available for the bug, including in the Metasploit framework.\nSee Also: Kali Linux 2022.1 Release with Visual Updates, New Tools, Legacy SSH See Also: Offensive Security Tool: Scapy Critical Concerns for AprilOut of the critical flaws, all of which allow remote code-execution (RCE), researchers flagged a bug that could allow for self-propagating exploits (CVE-2022-26809) as being of the most concern.\n\nIt exists in the Remote Procedure Call (RPC) Runtime Library, and rates 9.8 out of 10 on the CVSS scale, with exploitation noted as more likely. If exploited, a remote attacker could execute code with high privileges.\n\nDanny Kim, principal architect at Virsec, noted that the vulnerability is specifically found in Microsoft\u2019s Server Message Block (SMB) fu[...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-02T01:01:57.738665Z"}
