Loading vulnerability…
A buffer overflow vulnerability exists in the administrator authentication process of Kerio Personal Firewall (KPF) version 2.1.4 and earlier. The flaw is triggered when a specially crafted handshake packet is sent to the firewall, causing a buffer overflow condition that can be exploited to execute arbitrary code with the privileges of the firewall process.

This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability in the authentication process of Kerio Personal Firewall 2.1.4 (CVE-2003-0220). The exploit is implemented in Ruby and is designed to be used within the Metasploit Framework. It targets the administration service of the firewall, which listens by default on TCP port 44334. The exploit constructs a specially crafted authentication packet to trigger the overflow, allowing for arbitrary code execution with elevated privileges. The module supports multiple Windows targets (Windows 2000 Pro SP4, Windows XP Pro SP0/SP1) and allows for customizable payloads up to 800 bytes. The repository is operational and provides a working exploit, not just a proof of concept or detection script.
