Technical Details & Description:
================================
A remote sql-injection web vulnerability has been discovered  in the Quicksilver VoHo Concept4E 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 and `page` values of the `members.php`, `news.php`, `index.php`, 
`index2.php`, `updates.php` or `contacts.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 page and contentid values in the vulnerable marked *.php files. The security vulnerability is a classic order by sql injection 
bug in the page and id parameter.

The security risk of the sql-injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.4.
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
