Summary

FirmaCheck for Windows before 1.3.16 contains a DLL hijacking vulnerability that allows local attackers to execute arbitrary code by placing a crafted openssl.cnf file in the unvalidated C:\Program Files (x86)\Common Files\SSL\ directory path. Attackers can write a malicious OpenSSL configuration file referencing an attacker-controlled DLL to achieve code execution at startup process privilege level when FirmaCheck.exe runs automatically at system startup.

Risk Assessment

This vulnerability allows a local attacker to execute arbitrary code with startup process privileges, potentially leading to system compromise and security breach.

Recommendation

It is recommended to update FirmaCheck to version 1.3.16 or later and verify the integrity of configuration paths.
