A TOCTOU vulnerability exists in madCodeHook before 2020-07-16 that allows local attackers to elevate their privileges to SYSTEM. This occurs because path redirection can occur via vectors involving directory junctions.

Weakness

The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
