VMware Fusion(13.x prior to 13.5) contains a TOCTOU (Time-of-check Time-of-use) vulnerability that occurs during installation for the first time (the user needs to drag or copy the application to a folder from the .dmg volume) or when installing an upgrade. A malicious actor with local non-administrative user privileges may exploit this vulnerability to escalate privileges to root on the system where Fusion is installed or being installed for the first time.
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.
