Description

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.
