Product: Xavier - PHP Login Script & User Management Admin Panel 2.4
Exploitation Technique:
=======================
Remote
Severity Level:
===============
Medium
Technical Details & Description:
==============================
Multiple sql-injection vulnerabilities has been discovered in the Xavier PHP Login Script & User Management Admin Panel web-application.
The issue allows remote attackers to inject own malicious sql commands to compromise the web-application & database management system.
The sql-injection vulnerabilities are located in the `usertoedit` and `log_id` parameters of the `adminuserdit.php` and `editgroup.php` files.
Remote attackers with privileged user accounts are able to compromise the web-application and database management system by injection of sql
commands via GET method request. The attacker vector is client-side and the request method to inject the sql commands is GET. The vulnerability
is a classic order by sql-injection.
The security risk of the sql-injection web vulnerability is estimated as medium with a common vulnerability scoring system count of 5.3.
Exploitation of the remote sql-injection web vulnerability requires an authenticated web-application user account and no user interaction.
Successful exploitation of the sql-injection web vulnerability results in web-application or database management system compromise.
Request Method(s):
[+] GET
Vulnerable File(s):
[+] adminuseredit.php
[+] editgroup.php
Vulnerable Parameter(s):
[+] usertoedit
[+] log_id
Proof of Concept (PoC):
=======================
The remote sql-injection vulnerability can be exploited by authenticated user accounts without user interaction.

Solution - Fix & Patch:
=======================
The vulnerability can be patched by a parse via escape of the vulnerable parameters in the affected php files.
Restrict the prameter input and use a prepared statement to secure the functions of the admin panel.
Disallow to preview errors in the php code of the panel to prevent attacks.
Security Risk:
==============
The security risk of the sql-injection vulnerability in the web panel of the xavier application is estimated as medium (CVSS 5.3).
