CVE-2022-26318 is a critical unauthenticated remote code execution vulnerability in WatchGuard Firebox and XTM appliances, tracked by WatchGuard as FBX-22786. The flaw affects the Fireware OS management plane and is associated with the wgagent component’s XML-RPC login handling. Available technical reporting indicates the vulnerable attack surface includes the agent login functionality exposed through management interfaces, including the XML-RPC endpoint on port 4117, and related login paths reachable through the administrative web interface. A crafted login request, including malformed XML data and in observed cases gzip-compressed payloads, can trigger a buffer overflow in the vulnerable request-processing path and allow arbitrary code execution without authentication. Public analysis and exploitation reporting indicate successful exploitation can yield code execution in the appliance context, with post-exploitation access demonstrated as an interactive Python shell on affected systems. Affected versions include Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2.

This repository contains a single Metasploit module targeting CVE-2022-26318, a pre-authentication remote command execution vulnerability in WatchGuard Firebox and XTM appliances running vulnerable versions of Fireware OS. The exploit abuses a buffer overflow in the /agent/login endpoint of the administration interface (typically on ports 8080 or 4117), which is handled by a Python backend and a C binary (wgagent). The module checks for the presence of a WatchGuard Firebox by querying /auth/login, then delivers a specially crafted, gzipped XML-RPC payload to /agent/login to trigger the overflow and execute a reverse Python shell as the 'nobody' user. The payload is written to a temporary file in /tmp on the target and connects back to the attacker's machine, providing an interactive shell. The exploit is weaponized, allowing for customizable payloads and is suitable for operational use. The code is written in Ruby and is structured as a standard Metasploit module.
This repository contains a Python proof-of-concept exploit (POCwg.py) for CVE-2022-26318, a remote code execution vulnerability affecting WatchGuard XTM and FireWare OS devices. The exploit works by sending a specially crafted, gzipped HTTP POST request to the /agent/login endpoint on the target device (default port 4117, R_HOST). The payload is designed to trigger a buffer overflow and execute a Python-based reverse shell, connecting back to the attacker's machine (L_HOST) on port 8888. The attacker must have a netcat listener running to receive the shell. The repository consists of the exploit script and a brief README. The exploit is operational, providing a working reverse shell if the target is vulnerable and reachable.
This repository contains a single file, README.md, which includes a full Python proof-of-concept exploit for CVE-2022-26318, a remote code execution vulnerability in WatchGuard XTM and FireWare OS devices. The exploit crafts a malicious XML-RPC payload, compresses it with gzip, and sends it over an SSL-wrapped TCP connection to the target device's agent login service on port 4117. If successful, the payload causes the target device to open a reverse shell connection back to the attacker's machine (L_HOST) on port 8888, granting the attacker remote command execution. The exploit is operational, with a hardcoded Python reverse shell payload, and requires the attacker to set up a netcat listener to receive the shell. The code is self-contained and does not rely on any external frameworks. The repository is focused and provides a clear demonstration of the vulnerability's impact.
