Check Point Endpoint Security Initial Client for Windows before version E81.30 tries to load a DLL placed in any PATH location on a clean image without Endpoint Client installed. An attacker can leverage this to gain LPE using a specially crafted DLL placed in any PATH location accessible with write permissions to the user.
Executing commands or loading libraries from an untrusted source or in an untrusted environment can cause an application to execute malicious commands (and payloads) on behalf of an attacker.
The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product's direct control.
