A DLL sideloading vulnerability in McAfee Agent for Windows prior to 5.7.4 could allow a local user to perform a DLL sideloading attack with an unsigned DLL with a specific name and in a specific location. This would result in the user gaining elevated permissions and the ability to execute arbitrary code as the system user, through not checking the DLL signature.

Weakness

The product does not verify, or incorrectly verifies, the cryptographic signature for data.
