Improper access control vulnerability in the repair process for McAfee Agent for Windows prior to 5.7.4 could allow a local attacker to perform a DLL preloading attack using unsigned DLLs. This would result in elevation of privileges and the ability to execute arbitrary code as the system user, through not correctly protecting a temporary directory used in the repair process and not checking the DLL signature.

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
