Loading vulnerability…
A stack-based buffer overflow exists in the ovalarm.exe component of HP OpenView Network Node Manager (OV NNM) versions 7.01, 7.51, and 7.53. The vulnerability is triggered by sending a specially crafted HTTP request with an excessively long Accept-Language header to the OVABverbose action, resulting in a buffer overflow on the stack.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in HP OpenView Network Node Manager 7.53, specifically in the ovalarm.exe CGI component. The exploit works by sending a specially crafted HTTP GET request to the '/OvCgi/ovalarm.exe' endpoint, with an 'Accept-Language' header exceeding 100 bytes and the 'OVABverbose' URI variable set to '1'. This triggers a buffer overflow in the isWide function, allowing arbitrary code execution. The module supports custom Metasploit payloads (such as reverse shells), which are injected via the overflowed header. The exploit is operational and has been tested with a reverse_ord_tcp payload. The code is written in Ruby and is structured as a standard Metasploit exploit module, making use of the Metasploit framework's HTTP client and payload handling capabilities. The only fingerprintable endpoint is the '/OvCgi/ovalarm.exe' CGI path, which must be accessible on the target system for exploitation.
