Exploitation Technique:
=======================
Remote


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


Technical Details & Description:
================================
A remote sql-injection web vulnerability has been discovered in the official Techsoft Content Management System (2016 Q2).
The vulnerability allows remote attackers to execute own sql commands to compromise the web-applicaation or connected dbms.

The vulnerabilities are located in the `id` and `newsid` values of the `Content_sub.php`, `news_detail.php`, `ward.php`, 
`package_list.php`, `association.php` and `packages.php`files. 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 of the online service.
The injection points are the id and newsid values in the vulnerable marked php files. The security vulnerability is a classic 
order by sql injection bug.

The security risk of the sql-injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.2.
Exploitation of the remote sql injection web vulnerability requires no user interaction or privileged web-application user accounts.
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):
				[+] Content_sub.php
				[+] news_detail.php
				[+] ward.php
				[+] package_list.php
				[+] association.php
				[+] packages.php

Vulnerable Parameter(s):
				[+] id
				[+] newsid


Proof of Concept (PoC):
=======================
The remote sql-injection web vulnerability can be exploited by remote attackers without user interaction or privileged web-application user accounts.
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 php files. 
Encode and parse also the input of the vulnerable id and newsid values to prevent sql injection or script code injection attacks.
Restrict the input with a filter mechanism and disallow the usage of special chars. Escape and use entities to define clean and secure values.


Security Risk:
==============
The security risk of the remote sql injection web vulnerabilities in the cms web-application are estimated as high. (CVSS 7.2)
