CVE-2022-0799

Insufficient policy enforcement in Installer in Google Chrome on Windows prior to 99.0.4844.51 allowed a remote attacker to perform local privilege escalation via a crafted offline installer 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.
