Technical description

The GC-AGENTS-SERVICE running as part of Akamai´s Guardicore Platform Agent for Windows versions prior to v49.20.1, v50.15.0, v51.12.0, v52.2.0 is affected by a local privilege escalation vulnerability. The service will attempt to read an OpenSSL configuration file from a non-existent location that standard Windows users have default write access to. This allows an unprivileged local user to create a crafted "openssl.cnf" file in that location and, by specifying the path to a custom DLL file in a custom OpenSSL engine definition, execute arbitrary commands with the privileges of the Guardicore Agent process. Since Guardicore Agent runs with SYSTEM privileges, this permits an unprivileged user to fully elevate privileges to SYSTEM level in this manner.

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.
