HIGH Summary
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.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Leveraging/Manipulating Configuration File Search Paths This attack loads a malicious resource into a program's standard path used to bootstrap and/or provide contextual information for a program like a path variable or classpath. J2EE applications and other component based applications that are built from multiple binaries can have very long list of dependencies to execute. If one of these libraries and/or references is controllable by the attacker then application controls can be circumvented by the attacker. A standard UNIX path looks similar to this If the attacker modifies the path variable to point to a locale that includes malicious resources then the user unwittingly can execute commands on the attackers' behalf: This is a form of usurping control of the program and the attack can be done on the classpath, database resources, or any other resources built from compound parts. At runtime detection and blocking of this attack is nearly impossible, because the configuration allows execution.

| description | The remote host is running a version of Checkpoint Endpoint Security Initial Client. that is vulnerable to a local privilege escalation vulnerability. The vulnerability exists because vulnerable versions attempt to load a DLL that is placed in any PATH location on a clean install. An attacker could leverage this by creating a specially crafted DLL and placing it in any PATH location, when the victim installs Check Point Endpoint Security Initial Client, the DLL will be executed as that user.
