Vulnerability Disclosure Timeline:

2015-05-18: Public Disclosure (Vulnerability Laboratory)

Discovery Status:

Published

Affected Product(s):

Crucial Networking LLC
Product: CRUCMS - Content Management System 2015 Q2

Exploitation Technique:

Remote

Severity Level:

High

Technical Details & Description:

Multiple remote sql injection vulnerabilities has been discovered in the official Crucial Networking - CRUCMS web-application (2015 Q2).
The vulnerability allows remote attackers to execute own sql commands to compromise the web-applicaation or database management system.

The vulnerabilities are located in the id value of the `projects-cat.php`,`kitchen-chefs-detail.php` and `gallery-view.php` files.
Remote attackers are able to execute own sql commands by manipulation of the GET method request with the vulnerable id value.
The request method to inject the command is GET and the issue is located on the application-side.

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 privilege 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):
[+] projects-cat.php
[+] kitchen-chefs-detail.php
[+] gallery-view.php

Vulnerable Parameter(s):
[+] id

Proof of Concept (PoC):

The sql Injection web vulnerability can be exploited by remote attackers without privilege web-application user account or user interaction.
