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

Abstract:

The Vulnerability Laboratory Team discovered multiple Vulnerabilities in the DHTMLX v.3.0 Professional|Standard Edition.

Report-Timeline:

2012-04-10: Public or Non-Public Disclosure

Status:

Published

Exploitation-Technique:

Remote

Severity:

High

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.

[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 …

Risk:

1.1
The security risk of the sql injection vulnerability via POST is estimated as high(-).

1.2
The security risk of the persistent input validation vulnerabilities are estimated as medium(+).
