Descriptions

An issue was discovered in Veritas Desktop and Laptop Option (DLO) before 9.4. On start-up, it loads the OpenSSL library from /ReleaseX64/ssl. This library attempts to load the /ReleaseX64/ssl/openssl.cnf configuration file, which does not exist. By default, on Windows systems, users can create directories under C:\. A low privileged user can create a C:/ReleaseX64/ssl/openssl.cnf configuration file to load a malicious OpenSSL engine, resulting in arbitrary code execution as SYSTEM when the service starts. This gives the attacker administrator access on the system, allowing the attacker (by default) to access all data, access all installed applications, etc. This impacts DLO server and client installations.

Se detectó un problema en Veritas Desktop and Laptop Option (DLO) versiones anteriores a 9.4. Al iniciarse, carga la biblioteca OpenSSL desde /ReleaseX64/ssl. Esta biblioteca intenta cargar el archivo de configuración /ReleaseX64/ssl/openssl.cnf, que no existe. Por defecto, en los sistemas Windows, los usuarios pueden crear directorios en C:\. Un usuario poco privilegiado puede crear un archivo de configuración C:/ReleaseX64/ssl/openssl.cnf para cargar un motor OpenSSL malicioso, resultando en una ejecución de código arbitraria como SYSTEM cuando se inicia el servicio. Esto le otorga al atacante acceso de administrador al sistema, permitiendo al atacante (por defecto) acceder a todos los datos, acceder a todas las aplicaciones instaladas, etc. Esto afecta las instalaciones de cliente y de servidor de DLO
