CVE-2020-10138

• Severity: high (CVSS 7.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-284

Description

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 15: before 15 — fixed in 15

How to fix

Upgrade to a fixed version: Acronis Cyber Backup 12.5; Acronis Cyber Protect 15 15. Check the vendor advisory for mitigations.
