The issue concerns an OpenSSL component in Acronis True Image 2021, where the OPENSSLDIR variable is specified as a subdirectory within C:jenkins agent. This component is used by a privileged service within Acronis True Image. An unprivileged Windows user can create subdirectories off the system root, potentially allowing the creation of a specially-crafted openssl.cnf file. This could lead to arbitrary code execution with SYSTEM privileges.
