HP OpenView NNM 7.53, 7.51 OVAS.EXE Pre-Authentication Stack Buffer Overflow



This module exploits a stack buffer overflow in HP OpenView Network Node Manager versions 7.53 and earlier. Specifically this vulnerability is caused by a failure to properly handle user supplied input within the HTTP request including headers and the actual URL GET request. Exploitation is tricky due to character restrictions. It was necessary to utilize a egghunter shellcode which was alphanumeric encoded by muts in the original exploit. If you plan on using exploit this for a remote shell, you will likely want to migrate to a different process as soon as possible. Any connections get reset after a short period of time. This is probably some timeout handling code that causes this.

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