FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, FreeScout's module installation feature extracts ZIP archives without validating file paths, allowing an authenticated admin to write files arbitrarily on the server filesystem via a specially crafted ZIP. Version 1.8.215 fixes the vulnerability.
