Loading vulnerability…
CVE-2024-6594 is an improper handling of exceptional conditions vulnerability in the WatchGuard Single Sign-On Client for Windows. The flaw is triggered when the client processes malformed commands and fails to safely handle the exceptional input condition, causing the client to crash. An attacker with network access to the client can repeatedly send malformed commands to disrupt operation of the Single Sign-On service.

This repository contains a Python proof-of-concept exploit (wgclient.py) targeting multiple vulnerabilities (CVE-2024-6592, CVE-2024-6593, CVE-2024-6594) in the Watchguard SSO Agent. The script provides three main capabilities: (1) issuing arbitrary commands to the SSO client via its Telnet interface, (2) retrieving log files (which may include sensitive crash dumps), and (3) calculating authentication bypass secrets based on the agent's banner, allowing unauthorized access to the management interface. The exploit interacts with the SSO Agent over TCP (default port 4116), and requires the target's hostname or IP address. The repository consists of a single Python exploit script, a README with usage instructions and CVE references, and a license file. The exploit is a proof-of-concept and demonstrates the vulnerabilities without weaponization or automation for mass exploitation.
