Loading vulnerability…
A vulnerability in the URL handler of IBM Lotus Notes 8.x before 8.5.3 FP2 allows remote attackers to execute arbitrary code by enticing a user to open a specially crafted notes:// URL. The handler fails to properly validate or sanitize input, leading to code execution in the context of the user.

This repository contains a single Metasploit module (notes_handler_cmdinject.rb) that exploits a command injection vulnerability (CVE-2012-2174) in the IBM Lotus Notes Client URL handler on Windows (<= 8.5.3). The exploit works by serving a malicious HTML page that, when visited by a victim with a vulnerable Lotus Notes installation, triggers a specially crafted notes:// URL. This URL abuses the handler to execute arbitrary commands, ultimately downloading and running a Metasploit payload (such as Meterpreter) on the victim's machine. The module uses a combination of JavaScript and Windows command-line tricks to stage and execute the payload. The exploit targets users browsing with vulnerable browsers (e.g., IE8, Chrome 23) on Windows XP SP3. The main attack vector is browser-based, leveraging the network to deliver the payload. The module also includes cleanup routines to remove dropped files after exploitation. The structure is typical for a Metasploit exploit: it defines options, handles HTTP requests, generates payloads, and manages sessions. No hardcoded IPs or domains are present; all endpoints are dynamically generated at runtime.
