Loading vulnerability…
A stack-based buffer overflow exists in the Persits.XUpload.2 ActiveX control (XUpload.ocx) version 3.0.0.4 and earlier, part of Persits XUpload 3.0. The vulnerability is triggered by passing an excessively long argument to the AddFile method, which can overwrite stack memory and allow for arbitrary code execution.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in the Persits XUpload ActiveX control (version 3.0.0.3), which is included with HP LoadRunner 9.5. The exploit is delivered via a malicious HTML page served by the Metasploit framework's HTTP server. When a victim visits the page using Internet Explorer (typically on Windows XP SP3), the exploit triggers the AddFile method of the vulnerable ActiveX control with an overly long string, resulting in arbitrary code execution. The module allows for customizable payloads and is operational, requiring the victim to browse to the attacker's server. The main fingerprintable endpoint is the HTTP server root ("/"), and the exploit specifically targets the ActiveX control identified by CLSID E87F6C8E-16C0-11D3-BEF7-009027438003. The repository is structured as a single Ruby file compatible with the Metasploit framework.
