CVE-2009-3849 describes multiple stack-based buffer overflow vulnerabilities in HP OpenView Network Node Manager (OV NNM) versions 7.01, 7.51, and 7.53. The vulnerabilities exist in the nnmRptConfig.exe and snmp.exe components, where improper handling of user-supplied input to the Template and Oid parameters, respectively, allows attackers to overflow stack buffers via long parameter values. The nnmRptConfig.exe issue is related to unsafe usage of the strcat function.

This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability (CVE-2009-3849) in HP OpenView Network Node Manager 7.50's Snmp.exe CGI component. The exploit works by sending a specially crafted HTTP GET request to the '/OvCgi/Main/Snmp.exe' endpoint, overflowing the 'Oid' parameter to gain control of execution flow and execute arbitrary code. The module is written in Ruby and leverages the Metasploit framework's payload system, allowing the attacker to specify a custom payload (such as a reverse shell). The exploit is operational and requires the target to be running the vulnerable version of HP OpenView NNM on Windows 2000, with the Snmp.exe CGI accessible over the network. The repository structure is typical for Metasploit modules, with the exploit logic contained in a single Ruby file.
