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.

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)
