|

|
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.
