Title
Improper privilege management in repair process of MA for Windows
Summary
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.
