CVE-2026-41447

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.

Summary		(es) FirmaCheck para Windows anterior a 1.3.16 contiene una vulnerabilidad de secuestro de DLL que permite a atacantes locales ejecutar código arbitrario al colocar un archivo openssl.cnf manipulado en la ruta de directorio no validada C:\Program Files (x86)\Common Files\SSL\. Los atacantes pueden escribir un archivo de configuración de OpenSSL malicioso que hace referencia a una DLL controlada por el atacante para lograr la ejecución de código a nivel de privilegio del proceso de inicio cuando FirmaCheck.exe se ejecuta automáticamente al inicio del sistema.
