-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell ZENworks. Authentication is not
required to exploit this vulnerability.

The specific flaw exists within the ZENworks Server (zenserver.exe).
This Tomcat server listens by default on TCP ports 80 and 443. The
vulnerability exists in the UploadServlet. Using the UploadServlet an
attacker can upload a malicious file outside of the TEMP directory on
the server. By accessing this uploaded file remotely it is executed in
the context of the zenserver.exe process. This can be exploited to gain
arbitrary code execution in the context of the user running the ZENworks
server.
