Loading vulnerability…
A buffer overflow vulnerability exists in ovwebsnmpsrv.exe, a component of HP OpenView Network Node Manager (OV NNM) versions 7.51 and 7.53. The vulnerability can be triggered by sending specially crafted parameters to jovgraph.exe, leading to a buffer overflow condition. This flaw allows remote attackers to execute arbitrary code on the affected system.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in HP OpenView Network Node Manager (NNM) 7.53 (prior to NNM_01203) on Windows. The exploit abuses the 'jovgraph.exe' CGI program accessible at the /OvCgi/jovgraph.exe endpoint. By sending a specially crafted 'arg' parameter in either a GET or POST request, the module overflows a 1024-byte stack buffer, overwrites the SEH (Structured Exception Handler), and executes arbitrary shellcode. The exploit is operational and allows for customizable payloads, such as reverse shells, using Metasploit's payload system. The module includes multiple targets for different Windows versions and DLLs. The only file in the repository is a Ruby script structured as a standard Metasploit exploit module, and it leverages Metasploit's HttpClient and SEH exploitation mixins. The main fingerprintable endpoint is the /OvCgi/jovgraph.exe path, which is used to trigger the vulnerability.
