CVE-2020-7319

Improper Access Control vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 September 2020 Update allows local users to access files which the user otherwise would not have access to via manipulating symbolic links to redirect McAfee file operations to an unintended file.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Potential Mitigations

• Follow the principle of least privilege when assigning access rights to entities in a software system.
• Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
