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.
