Arbitrary Code Execution in Acronis True Image Due to OpenSSL Misconfiguration

CVE-2020-10139

What is CVE-2020-10139?

Acronis True Image 2021 incorporates an OpenSSL component with a misconfigured OPENSSLDIR variable that points to a subdirectory within C:\jenkins_agent. The software contains a privileged service that utilizes this OpenSSL component. Because standard Windows users can create subdirectories off the system root, an unprivileged user could potentially craft a specially-designed openssl.cnf file within the specified directory, enabling them to execute arbitrary code with SYSTEM-level privileges. This vulnerability poses a significant risk as it allows unauthorized users to manipulate system operations and gain control over critical system resources.
