CVE-2020-10138: Acronis Cyber Backup

High severity, CVSS 7.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Acronis Cyber Backup: before 12.5 (fixed in 12.5)
• Acronis Cyber Protect: before 15 (fixed in 15)
