CVE-2021-41562

A vulnerability in Snow Snow Agent for Windows allows a non-admin user to cause arbitrary deletion of files. This issue affects: Snow Snow Agent for Windows version 5.0.0 to 6.7.1 on Windows.

Weakness

The product, when opening a file or directory, does not sufficiently handle when the file is a Windows shortcut (.LNK) whose target is outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.

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.
