Mangallam CMS - SQL Injection Web Vulnerability

Technical Details & Description:
================================
A remote sql injection web vulnerability has been discovered in the official Mangallam Content Management System 2015-Q1.
The sql vulnerability allows an attacker to inject sql commands to compromise the application & database management system.
 
The sql injection vulnerability is located in the `newsid` value of the vulnerable `news_view.php` application file. Remote attackers
are able to inject own sql commands by  manipulation of the vulnerable newsid value in the `news_view.php` file. A successful attack
requires to manipulate a GET method request with vulnerable `newsid` value to inject own sql commands. The injection is a classic
order by sql injection that allows to compromise the web-application and connected database management system. The request method to
inject own sql commands is GET and the vulnerability is located on the application-side of the service.
 
The security risk of the sql injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 8.9.
Exploitation of the application-side web vulnerability requires no privileged web-application user account and no user interaction.
Successful exploitation of the security vulnerability result in web-application and database management system compromise.
 
Request Method(s):
                [+] GET
 
Vulnerable Module(s):
                [+] News
 
Vulnerable File(s):
                [+] news_view.php
 
Vulnerable Parameter(s):
                [+] newsid
 
 
Proof of Concept (PoC):
=======================
The remote sql injection web vulnerability can be exploited by remote attackers without privileged application user account or user interaction.
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.
 
Dork(s):
allinurl:news_view.php?newsid=

PoC:
http://localhost:8080/news_view.php?newsid=-1'[REMOTE SQL-INJECTION VULNERABILITY!]--
 
 
Reference(s):
http://localhost:8080/news_view.php
 
 
Solution - Fix & Patch:
=======================
The remote vulnerability can be patched by usage of a prepared statement next to the newsid GET method request.
Restrict and filter the newsid value and disallow input of special chars. Prevent disaplaying of php errors by usage of the (0)error (php) function.
 
 
 
Security Risk:
==============
The security risk of the remote sql injection web vulnerability in the content management system is estimated as critical.
