vtiger CRM <= 5.4.0 (customerportal.php) Two Local File Inclusion Vulnerabilities
---------------------------------------------------------------------------------

[-] Affected Versions:

[1] All versions from 5.1.0 to 5.4.0.
[2] All versions from 5.2.0 to 5.4.0.


[-] Vulnerability Description:

1) The vulnerable code is located in the get_list_values SOAP method defined in /soap/customerportal.php:

1528.	function get_list_values($id,$module,$sessionid,$only_mine='true')
1529.	{
1530.		require_once('modules/'.$module.'/'.$module.'.php');
1531.		require_once('include/utils/UserInfoUtil.php');
1532.		global $adb,$log,$current_user;
1533.		$log->debug("Entering customer portal function get_list_values");

2) The vulnerable code is located in the get_project_components SOAP method defined in /soap/customerportal.php:

2778.	function get_project_components($id,$module,$customerid,$sessionid) {
2779.		require_once("modules/$module/$module.php");
2780.		require_once('include/utils/UserInfoUtil.php');
2781.	
2782.		global $adb,$log;
2783.		$log->debug("Entering customer portal function get_project_components ..");

The vulnerabilities exist because these methods fail to properly validate input passed through the "module"
parameter, that is being used in a call to the require_once() function (lines 1530 and 2779). This might be
exploited to include arbitrary local files containing malicious PHP code. Successful exploitation of these
vulnerabilities requires the application running on PHP < 5.3.4, because a null byte injection is required.
