CVE-2022-0029

An improper link resolution vulnerability in the Palo Alto Networks Cortex XDR agent on Windows devices allows a local attacker to read files on the system with elevated privileges when generating a tech support 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.
