Loading vulnerability…
A stack-based buffer overflow exists in the SonicWall SSL-VPN NetExtender NELaunchCtrl ActiveX control in versions prior to 2.1.0.51 and 2.5.x prior to 2.5.0.56. The vulnerability is triggered by passing an overly long string as the second argument to the AddRouteEntry method, allowing remote attackers to execute arbitrary code in the context of the user running the control.

This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability in the SonicWall SSL-VPN NetExtender ActiveX control (NELaunchX.dll version 1.0.0.26). The exploit is delivered via a malicious HTML page served by the Metasploit framework, which instantiates the vulnerable ActiveX control in Internet Explorer 6 on Windows XP SP2 Pro English. The exploit triggers the overflow by passing an overly long string to the AddRouteEntry() method, allowing arbitrary code execution with the privileges of the user running the browser. The module supports customizable payloads via the Metasploit framework and is operational, requiring the victim to visit the attacker's page with a vulnerable configuration. The main fingerprintable endpoint is the ActiveX control's CLSID (6EEFD7B1-B26C-440D-B55A-1EC677189F30) and the NELaunchX.dll file. The repository is structured as a single Ruby file following Metasploit's exploit module conventions.
