HP OpenView Network Node Manager snmpviewer.exe Buffer Overflow



This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53 prior to NNM_01203. By making a specially crafted HTTP request to the "snmpviewer.exe" CGI program, an attacker can cause a stack-based buffer overflow and execute arbitrary code. The vulnerable code lies within a function within "snmpviewer.exe" with a timestamp prior to April 7th, 2010. This vulnerability is triggerable via either a GET or POST request. The request must contain 'act' and 'app' parameters which, when combined, total more than the 1024 byte stack buffer can hold. It is important to note that this vulnerability must be exploited by overwriting SEH. While the saved return address can be smashed, a function call that occurs before the function returns calls "exit".

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/windows/http/hp_nnm_snmpviewer_actapp
msf exploit(hp_nnm_snmpviewer_actapp) > show targets
msf exploit(hp_nnm_snmpviewer_actapp) > set TARGET < target-id >
msf exploit(hp_nnm_snmpviewer_actapp) > show options
    ...show and set options...
msf exploit(hp_nnm_snmpviewer_actapp) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
