https://notcve.org/view.php?id=CVE-2021-31954
Windows Common Log File System Driver Elevation of Privilege Vulnerability Una vulnerabilidad de Escalada de Privilegios en Windows Common Log File System Driver This vulnerability allows local attackers to escalate privileges on affected installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the clfs.sys driver. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31954 https://www.zerodayinitiative.com/advisories/ZDI-21-668 • CWE-122: Heap-based Buffer Overflow CWE-269: Improper Privilege Management •
