| CVE-2022-24521 | Microsoft Windows CLFS Driver Privilege Escalation Vulnerability | secondary_impact | T1059 | Command and Scripting Interpreter |
Comments
This vulnerability is exploited by an attacker who has already obtained access to a target system to execute code. The vulnerability lies in the Common Log File System (CLFS) driver, specifically in the `CClfsBaseFilePersisted::LoadContainerQ()` function, due to a logic bug in handling container context objects. This vulnerability has been exploited by threat actors to gain elevated privileges on Windows systems. Attackers leveraged this flaw to execute arbitrary code with system-level privileges, allowing them to manipulate system processes and deploy additional malware to perform further malicious activities.
The exploit in question is actively being used in the wild, primarily in ransomware campaigns. It involves corrupting the `pContainer` field of a container context object with a user-mode address by using malformed BLF files. Once the vulnerability is exploited, attackers can manipulate memory to execute code with elevated privileges. This allows them to achieve their objectives, such as stealing the System token and gaining full control over the compromised system.
