Security Advisory - Checkpoint Endpoint Connect VPN - DLL Hijack
Summary : Checkpoint Endpoint Connect VPN is prone to DLL hijacking
Date : 12 June 2012
Affected versions : Endpoint Security VPN R75
Remote Access Clients E75.x
Endpoint Security R73.x/E80.x (VPN blade)
ID : sk76480
CVE reference : CVE-2012-2753

A vulnerability in Checkpoint Endpoint Connect VPN causes the client to be
susceptible to an attack that result in arbitrary dynamic-library loading.

A user with local disk access can carefuly construct a DLL that suits a pattern
that is being traversed by the client and implement it somewhere along the
search path and the client will load it seamlessly.

After the DLL has been implemented, an unsuspected user that will run the
program will cause it to load, resulting in arbitrary code execution with
user's privilege level.
