HP OpenView Network Node Manager ovalarm.exe CGI Buffer Overflow



This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53. By sending a specially crafted CGI request to ovalarm.exe, an attacker can execute arbitrary code. This specific vulnerability is due to a call to "sprintf_new" in the "isWide" function within "ovalarm.exe". A stack buffer overflow occurs when processing an HTTP request that contains the following. 1. An "Accept-Language" header longer than 100 bytes 2. An "OVABverbose" URI variable set to "on", "true" or "1" The vulnerability is related to "_WebSession::GetWebLocale()". NOTE: This exploit has been tested successfully with a reverse_ord_tcp payload.

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