A buffer overflow vulnerability exists in nnmRptConfig.exe in HP OpenView Network Node Manager (OV NNM) versions 7.51 and 7.53. The vulnerability is triggered by sending a specially crafted request with an overly long nameParams parameter, resulting in a buffer overflow condition. This flaw is distinct from CVE-2011-0267.

This repository contains a single Metasploit module targeting a buffer overflow vulnerability (CVE-2011-0266) in HP OpenView Network Node Manager's nnmRptConfig.exe CGI component. The exploit works by sending a specially crafted POST request to the /OvCgi/nnmRptConfig.exe endpoint, overflowing the nameParams parameter and allowing for arbitrary code execution. The module supports two specific targets: NNM 7.53 on Windows Server 2003 Enterprise and NNM 7.50. The payload is fully customizable using Metasploit's payload system, making this a weaponized exploit. The code is written in Ruby and leverages Metasploit's HTTP client and SEH exploitation mixins. The only fingerprintable endpoint is the vulnerable CGI path. The repository is structured as a single exploit module file, designed for use within the Metasploit Framework.
