CVE-2009-0920 is a stack-based buffer overflow vulnerability in the OvCgi/Toolbar.exe component of HP OpenView Network Node Manager (OV NNM) versions 7.01, 7.51, and 7.53. The vulnerability is triggered by a long OvOSLocale cookie in an HTTP request, which is improperly handled by the application, leading to a buffer overflow in the stack. The vulnerable code path involves the _vsnprintf function in msvcrt.dll, called from ovutil.dll and ov.dll. This flaw allows remote attackers to execute arbitrary code with the privileges of the NNM process.

This repository contains a single Metasploit module (modules/exploits/windows/http/hp_nnm_toolbar_02.rb) that exploits a stack buffer overflow vulnerability in HP OpenView Network Node Manager (NNM) versions 7.0 and 7.53 (specifically build 7.53_01195) on Windows platforms. The exploit targets the Toolbar.exe CGI component, accessible via HTTP at /OvCgi/Toolbar.exe. By sending a specially crafted OvOSLocale cookie in an HTTP GET request, the module triggers a buffer overflow, allowing arbitrary code execution. The module supports two main targets: Windows XP SP3 (NNM 7.0) and Windows Server 2003 (NNM 7.53_01195), with specific return addresses and buffer offsets for each. The payload is customizable via the Metasploit framework and is delivered as x86 shellcode. The exploit is operational and can be used to gain remote code execution on vulnerable systems. The repository is structured as a typical Metasploit exploit module, with all logic contained in a single Ruby file.
