Technical Details & Description:
|
|
================================
|
|
A remote sql-injection vulnerability has been discovered in the official creative zone web-application.
|
|
The vulnerability allows remote attackers to inject or execute own sql commands to compromise the dbms
|
|
or file system of the application.
|
|
|
|
The sql-injection web vulnerability is located in the `newUser` and `editUser` function of the `users` module in
|
|
the `admin.php` file. Remote attackers with privileged access to the panel are able to add users. If a user account
|
|
already exists like for example the admin account, each add of the same name or email values results in a unfiltered
|
|
mysql exception. The exception is not filtered and sanitized. Thus allows privileged attackers to inject and execute
|
|
own sql commands on the affected database management system to compromise. The request method to inject is post and
|
|
the attack vector is non-persistent.
|
|
|
|
Exploitation of the sql injection vulnerability requires user interaction and a privileged web-application user account.
|
|
Successful exploitation of the remote sql injection results in database management system, web-server and web-application compromise.
|
|
|
|
Request Method(s):
|
|
[+] POST
|
|
|
|
Vulnerable Module(s):
|
|
[+] newUser
|
|
[+] editUser
|
|
|
|

|
|
[+] admin.php?act=users
|
|
|
|
Vulnerable Input(s):
|
|
[+] Name
|
|
[+] Username
|
|
[+] Password
|
|
|
|
Vulnerable Parameter(s):
|
|
[+] name
|
|
[+] username
|

|
Proof of Concept (PoC):
|
|
=======================
|
|
The remote sql-injection web vulnerability can be exploited by remote attackers with privileged account and without user interaction.

Error: SELECT * FROM cms2_users WHERE username='a%20-1'
|
|
Error: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '%20-1'' at line 1
|
|
|
|
|
|
Solution - Fix & Patch:
|
|
=======================
|
|
1. Disallow sql-errors to be displayed in the frontend and backend. Disable to redisplay the broken or malicious query on client-side.
|
|
2. Use prepared statement to protect the sql query of the post method request
|
|
3. Restrict the post parameters by disallow the usage of special chars with single or double quotes
|
|
4. Setup a filter or validation class to deny broken or manipulated sql queries
