Overview

CVE-2020-36160 is a critical-severity vulnerability. It was published on January 6, 2021 and has a CVSS 3.1 base score of 9.3 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.3, rated CRITICAL. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

An issue was discovered in Veritas System Recovery before 21.2. On start-up, it loads the OpenSSL library from \usr\local\ssl. This library attempts to load the from \usr\local\ssl\openssl.cnf configuration file, which does not exist. By default, on Windows systems, users can create directories under C:\. A low privileged user can create a C:\usr\local\ssl\openssl.cnf configuration file to load a malicious OpenSSL engine, resulting in arbitrary code execution as SYSTEM when the service starts. This gives the attacker administrator access on the system, allowing the attacker (by default) to access all data and installed applications, etc. If the system is also an Active Directory domain controller, then this can affect the entire domain.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
