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


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


Technical Details & Description:
================================
A remote sql injection web vulnerability has been discovered in the official Y-R-S Content Management System 2015-Q4.
The vulnerability allows remote attackers to execute own sql commands to compromise the web-applicaation or connected dbms.

The vulnerability is located in the `id` value of the `page.php` file. Remote attackers are able to execute own sql commands by 
manipulation of the GET method request with the vulnerable id parameter. The request method to inject the sql command is GET and 
the issue is located on the application-side of the `./yrs/` online-service path. The sql vulnerability allows remote attackers to 
compromise the database management system that is connected to the web-application.

The security risk of the sql injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 8.2.
Exploitation of the remote sql injection web vulnerability requires no user interaction or privileged web-application user account.
Successful exploitation of the remote sql injection results in database management system, web-server and web-application compromise.

Request Method(s):
						[+] GET

Vulnerable Module(s):
						[+] ./yrs/

Vulnerable File(s):
						[+] page.php

Vulnerable Parameter(s):
						[+] id


Proof of Concept (PoC):
=======================
The sql injection web vulnerability can be exploited by remote attackers without privileged web-application user account and without user interaction.
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 prepared statement in the entry request of the id value. Restrict all the url parameter requests and 
disallow usage of special chars to prevent sql or script code injection attacks. Escape or filter the entry to valid the context finally.



Security Risk:
==============
The security risk of the remote sql injection web vulnerability in the web application is estimated as high. (CVSS 8.2)
