Loading vulnerability…
HP OpenView Network Node Manager (OV NNM) 7.51 and 7.53 contains a buffer overflow in ovutil.dll used by ovwebsnmpsrv.exe. Unspecified variables supplied to jovgraph.exe are improperly handled when passed to sprintf, enabling a remote attacker to execute arbitrary code.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability (CVE-2010-1961) in HP OpenView Network Node Manager 7.53 (prior to NNM_01203) on Windows. The exploit abuses the 'arg' parameter of the /OvCgi/jovgraph.exe CGI endpoint, sending a specially crafted HTTP GET or POST request to trigger the overflow and execute arbitrary code. The module allows the attacker to supply a custom payload, typically resulting in remote code execution with the privileges of the ovwebsnmpsrv.exe process. The exploit is operational, but the module notes some reliability issues possibly related to session management. The only file present is a Ruby script structured as a standard Metasploit exploit module, and it includes all necessary logic to deliver the payload and handle responses. The main fingerprintable endpoint is the /OvCgi/jovgraph.exe path, which is used to identify and target vulnerable systems.
