Technical Details & Description:
================================
A remote sql-injection web vulnerability has been discovered in the AccelSite Content Manager v1.0 Content Management System.
The web vulnerability allows remote attackers to execute own sql commands to compromise the web-applicaation or connected dbms.

The sql-injection vulnerability is located in the `contentID value of the `index.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 of the online service. The injection points is the contentID value in the vulnerable index.php file. The security 
vulnerability is a classic order by sql injection bug in the contentID parameter.

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):
				[+] index.php

Vulnerable Parameter(s):
				[+] contentID


Proof of Concept (PoC):
=======================

PoC: Exploitation
http://localhost:8080/index.php?contentID=899%27-1[SQL-INJECTION VULNERABILITY!]--
http://localhost:8080/index.php?contentID=169%27-1[SQL-INJECTION VULNERABILITY!]--


Solution - Fix & Patch:
=======================
The sql-injection vulnerability can be patched by a secure parse and encode of the vulnerable contentID value in the index.php file GET method request.
Restrict the input and disallow usage of special chars. Prevent an execution by usage of a prepared statement in connection with stable set entities.
Escape the context as well at the end.


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