Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of Novell ZENworks Asset Management. Authentication 
is not required to exploit this vulnerability.

The specific flaw exists within a servlet provided within the Novell Zenworks 
distribution for uploading files. When processing the path name for the file, 
the servlet will allow a user to inject path traversal entities into the 
filename. Then, when the servlet downloads the provided file, the destination 
will store it to the user-provided location. This can lead to code execution 
under the context of the service.
