CVE-2022-37969 Microsoft Windows Common Log File System (CLFS) Driver Privilege Escalation Vulnerability secondary_impact T1059 Command and Scripting Interpreter
Comments
This vulnerability is exploited by an attacker who has obtained access to the target system. The vulnerability lies in the Windows Common Log File System (CLFS) Driver, specifically due to improper bounds checking on the `cbSymbolZone` field in the Base Record Header for the base log file (BLF). This vulnerability has been exploited by threat actors to gain elevated privileges on Windows systems. Attackers leveraged this flaw to execute arbitrary system commands, allowing them to manipulate system processes and potentially deploy additional malware or perform further malicious activities. The exploit in question is actively being used in the wild, primarily in targeted attacks. It involves setting the `cbSymbolZone` field to an invalid offset, triggering an out-of-bound write that corrupts a pointer to the CClfsContainer object. Once the vulnerability is exploited, attackers can manipulate memory to perform arbitrary actions with SYSTEM-level privileges. This allows them to achieve their objectives, such as disabling security applications and gaining full control over the compromised system.
