What is CVE-2020-36168?
CVE-2020-36168 is a critical path traversal vulnerability in n/a, published on 6 Jan 2021. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
An issue was discovered in Veritas Resiliency Platform 3.4 and 3.5. It leverages OpenSSL on Windows systems when using the Managed Host addon. On start-up, it loads the OpenSSL library. This library may attempt to load the 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, access all installed applications, etc.
