'Name' => 'MaxDB WebDBM Database Parameter Overflow',

'Description'=> %q{

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.
