Overview
==========
This version of PHP Support Ticket is bundled together in today's one-click
script installer of all/most web hosting providers. Customers have no clue
of the vulnerabilities. Hosting providers always say marketing voice -
easy deployment, one-click installation - but no security.

#1. Lack Of "install" directory removal check

This will allow attackers to overwrite existing config files with junk data,
making the PHP Ticket application stop working. In extreme case, advanced
attackers will inject valid php codes to do more harm.

#2. Hidden Debug paramter (tri_debug)

File: /include/config.php
Code:
	// Conditional Error Reporting
	if (isset($_GET['tri_debug'])) {
		$set_ini = ini_set('display_errors', 1);
		error_reporting(E_ALL);

This will provide attackers every feedback for his attacking.
For small case, this provides internal path disclosure. 	

#3. Addon: PHPMailer Remote Code Execution

PHP Support Ticket employed vulnerable version of PHPMailer class.

File: /classes/class.phpmailer.php
Code:
	if ($this->Sender != "")
		$sendmail = sprintf("%s -oi -f %s -t", $this->Sendmail, $this->Sender);
	else
		$sendmail = sprintf("%s -oi -t", $this->Sendmail);

4. Possible Script Injection

A number of scripts use dangerous eval function without enough filtering.
File: /classes/GUI/abstract.GUI.php
Code:
	return eval('return PHPST_PAGENAME_' . strtoupper($this->page) . ';');
