Remote


Severity Level:
===============
High


Technical Details & Description:
================================
A remote sql-injection web vulnerability has been discovered in the official CentOS Web Panel v0.9.8.12 web-application.
The vulnerability allows remote attackers to inject own malicious sql commands to compromise the connected web-server or dbms.

The sql-injection vulnerability is located in the `row_id` and `domain` value of the `Add a domain` module POST method request.
Remote attackers are able to manipulate the POST method request to execute own malicious sql commands on the application-side 
of the web-application. The request method to inject is POST and the attack vector is application-side. The vulnerability can 
be exploited by restricted user accounts against the web-application administrator. 

The security risk of the sql-injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.5.
Exploitation of the remote sql injection vulnerability requires no user interaction and only a low 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):
[+] Add a domain

Vulnerable Parameter(s):
[+] row_id
[+] domain

Affected Module(s):
[+] Delete domain


Proof of Concept (PoC):
=======================
The remote sql-injecton vulnerability can be exploited by remote attackers with low privilege user account and without user interaction.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.


Manual steps to reproduce the vulnerability ...
1. Add a domain
2. Delete the same domain
3. Intercept the http request with a session tamper
4. Manipulate in the POST method request the values `row_id` or `domain` with '
5. Continue the request and an exploitable sql-exception becomes visible
6. Now the attacker can inject to the row_id and domain to execute malicious sql commands via restricted user account
7. Successful reproduce of the sql-injection vulnerability!
