CVE-2022-22262

ROG Live Service’s function for deleting temp files created by installation has an improper link resolution before file access vulnerability. Since this function does not validate the path before deletion, an unauthenticated local attacker can create an unexpected symbolic link to system file path, to delete arbitrary system files and disrupt system service.

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.
