HP OpenView Network Node Manager ovwebsnmpsrv.exe main Buffer Overflow



This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53 prior to NNM_01203. By specifying a long 'arg' parameter when executing the 'jovgraph.exe' CGI program, an attacker can cause a stack-based buffer overflow and execute arbitrary code. This vulnerability is triggerable via either a GET or POST request. The buffer being written to is 1024 bytes in size. It is important to note that this vulnerability must be exploited by overwriting SEH. Otherwise, CVE-2010-1961 is triggered! The vulnerable code is within the "main" function within "ovwebsnmpsrv.exe" with a timestamp prior to April 7th, 2010. There are no stack cookies, so exploitation is easily achieved by overwriting SEH structures. There exists some unreliability when running this exploit. It is not completely clear why at this time, but may be related to OVWDB or session management. Also, on some attempts OV NNM may report invalid characters in the URL. It is not clear what is causing this either.

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_ovwebsnmpsrv_main
msf exploit(hp_nnm_ovwebsnmpsrv_main) > show targets
msf exploit(hp_nnm_ovwebsnmpsrv_main) > set TARGET < target-id >
msf exploit(hp_nnm_ovwebsnmpsrv_main) > show options
    ...show and set options...
msf exploit(hp_nnm_ovwebsnmpsrv_main) > 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.
