CISA KEV Advisory
Microsoft Windows Authenticode Signature Verification Remote Code Execution Vulnerability
The Authenticode Signature Verification function in Microsoft Windows (WinVerifyTrust) does not properly validate the digest of a signed portable executable (PE) file, which allows user-assisted remote attackers to execute code.
Apply updates per vendor instructions.
Risk Analysis
A flaw in the Authenticode Signature Verification function (WinVerifyTrust) in Microsoft Windows allows user-assisted remote attackers to execute code. This is a critical vulnerability due to its high EPSS score of 0.89010, indicating a very high likelihood of exploitation, and its inclusion in CISA's KEV confirms active exploitation.
This vulnerability is actively being exploited in the wild. User interaction is required for remote attackers to execute code.
Apply all available security updates for Microsoft Windows to address this Authenticode verification flaw. Educate users on the risks of opening untrusted signed portable executable files.
Technical Analysis
CVE-2012-0151 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2012-0151 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
