Discovery Status:
=================
Published


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


Severity Level:
===============
Critical


Technical Details & Description:
================================
A remote sql injection web vulnerability has been discovered in the official Data Source Scopus Content Management System.
The vulnerability allows remote attacker to inject own sql commands to compromise the affected database management system.

The vulnerability is located in the `w` value of the `countrysearch.php` file. Remote attackers are able to compromise the 
application & dbms by manipulation of the `w` value in the `countrysearch.php` file. The issue is a classic order by injection.
The request method to inject own commands is GET and the issue is located on the applicaiton-side of the service.

The security risk of the sql injection vulnerability is estimated as critical with a cvss (common vulnerability scoring system) count of 8.9.
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 dbms, web-server and web-application compromise.

Request Method(s):
				[+] GET

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

Vulnerable Parameter(s):
				[+] w


Proof of Concept (PoC):
=======================
The remote sql injection web vulnerability can be exploited by remote attackers without privileged application user account or user interaction.
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.

PoC: Example
http://[localhost]/[PATH]/[FILE].php?w=-[SQL INJECCTION VULNERABILITY]'--

PoC: Demonstration
http://www.server.com/countrysearch.php?w=world%27-[SQL INJECCTION VULNERABILITY]'--

Dork(s):
inurl:".php?w="


Solution - Fix & Patch:
=======================
The vulnerability can be patched by usage of the preapred statement in connection with a secure encode/parse of the w value in the countrysearch.php file.
Restrict the w value input and filter by disallowing input of special chars or negative values. Disable php script error(0);!


Security Risk:
==============
The security risk of the remote sql injection web vulnerability in the countrysearch.php file is estimated as critical.
