Technical Details & Description:  
================================  
A remote sql-injection web vulnerability has been discovered in the  
official Eight Webcom web-application (2016 Q2).  
The 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 `id` and `newsid`  
values of the `content.php`file. 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 point is the  
id value in the vulnerable content.php file.  
The security vulnerability is a classic order by sql injection bug in  
the id parameter.  
  
The security risk of the sql-injection vulnerability is estimated as  
high with a cvss (common vulnerability scoring system) count of 7.1.  
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.php  
  
Vulnerable Parameter(s):  
[+] id  
  
  
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.

PoC: Exploitation  
http://localhost:8080/content.php?id=25'[SQL-INJECTION VULNERABILITY!]--  
  
  
Solution - Fix & Patch:  
=======================  
The vulnerability can be patched by usage of a secure prepared statement  
and entities in the content.php file GET method request.  
Filter and restrict the input by disallowing the usage of special chars  
or escape the entries.  
Encode and parse the vulnerable id parameter context to finally prevent  
exploitation of the vulnerability.  
  
  
Security Risk:  
==============  
The security risk of the remote sql-injection web vulnerability in the  
content management system is estimated as high. (CVSS 7.1)
