High


Technical Details & Description:
================================
A remote sql injection web vulnerability has been discovered in the official Mutualaid CMS \
v4.3.1 content management system. The vulnerability allows remote attackers to execute own sql \
commands to compromise the web-applicaation or connected dbms.

The vulnerability is located in the `id - nid` parameter of the `article.php` file GET method \
request. Remote attackers are able  to execute sql commands by injection of malicious \
statements via GET method request. The vulnerability is located on the  application-side and \
the request method to inject/execute is GET. The security vulnerability is a classic order by \
sql injection  in the `id` or `nid` value. 

The security risk of the sql injection vulnerability is estimated as high with a cvss (common \
vulnerability scoring system) count of 7.6. Exploitation of the remote sql injection web \
vulnerability requires no user interaction or 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):
				[+] GET

Vulnerable File(s):
				[+] article.php

Vulnerable Parameter(s):
				[+] id - nid


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

Solution - Fix & Patch:
=======================
The vulnerability can be patched by usage of a secure prepared statement in the vulnerable file \
GET method request. Restrict the parameter and disallow special chars or escapte the entries \
permanently.


Security Risk:
