Loading vulnerability…
Green Dam Youth Escort 3.17 contains a stack-based buffer overflow in its URL filtering component. The component does not properly validate the length of user-supplied URLs before copying them into a fixed-size buffer. A specially crafted webpage containing an overly long URL can trigger the overflow when visited by a user, allowing remote arbitrary code execution.

This repository contains a single Metasploit module (greendam_url.rb) that exploits a stack-based buffer overflow vulnerability (CVE-2009-20008) in Green Dam Youth Escort 3.17. The exploit targets users running Internet Explorer 6 or 7 on Windows XP SP2/SP3 or Vista SP1. The module sets up a malicious HTTP server that serves a specially crafted HTML page with an overly long URL, triggering the buffer overflow in the Green Dam software when visited. The exploit uses a .NET DLL memory corruption technique to bypass modern mitigations like DEP and ASLR, delivering arbitrary shellcode to the victim. The payload is customizable via Metasploit. The main endpoints are the malicious HTML page and the dynamically generated .NET DLL. The repository is operational and weaponized for use within the Metasploit framework.
