Affected applications contain private SSL/TLS keys on the server that are not properly protected allowing any user with server access to read these keys. This could allow an authenticated attacker to impersonate the server potentially enabling man-in-the-middle, traffic decryption or unauthorized access to services that trust these certificates."

Las aplicaciones afectadas contienen claves privadas SSL/TLS en el servidor que no están protegidas adecuadamente, permitiendo a cualquier usuario con acceso al servidor leer estas claves. Esto podría permitir a un atacante autenticado suplantar al servidor, lo que podría habilitar man-in-the-middle, el descifrado de tráfico o el acceso no autorizado a servicios que confían en estos certificados."
