CVE-2022-1256

A local privilege escalation vulnerability in MA for Windows prior to 5.7.6 allows a local low privileged user to gain system privileges through running the repair functionality. Temporary file actions were performed on the local users %TEMP% directory with System privileges through manipulation of symbolic links.

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.
