Descriptions

Acronis Cyber Backup 12.5 and Cyber Protect 15 include an OpenSSL component that specifies an OPENSSLDIR variable as a subdirectory within C:\jenkins_agent\. Acronis Cyber Backup and Cyber Protect contain a privileged service that uses this OpenSSL component. Because unprivileged Windows users can create subdirectories off of the system root, a user can create the appropriate path to a specially-crafted openssl.cnf file to achieve arbitrary code execution with SYSTEM privileges.

Acronis Cyber ??Backup versión 12.5 y Cyber ??Protect versión 15 incluyen un componente OpenSSL que especifica una variable OPENSSLDIR como un subdirectorio dentro de C:\jenkins_agent\. Acronis Cyber ??Backup y Cyber ??Protect contienen un servicio privilegiado que usa este componente de OpenSSL. Debido a que los usuarios de Windows no privilegiados pueden crear subdirectorios fuera del root del sistema, un usuario puede crear la ruta apropiada a un archivo openssl.cnf especialmente diseñado para lograr una ejecución de código arbitraria con privilegios del SYSTEM
