Product: Zenbership - Content Management System (Web-Application) 1.0.8
Exploitation Technique:
=======================
Remote
Severity Level:
===============
Medium
Technical Details & Description:
================================
The sql-injection vulnerability allows remote attackers or privileged user accounts to execute malicious sql commands to
compromise the web-application and database management system.
The vulnerabilities are located in the `error_codes`, `subscriptions`, `widget` and `logins` parameters of the `./admin/index.php`
file. Attackers with privileged web-application user accounts are able to execute malicious sql commands via GET method request.
The requested content of the files is not sanitized via parse or escape.
The security risk of the vulnerabilities are estimated as medium with a common vulnerability scoring system count of 5.3.
Exploitation of the sql-injection vulnerability requires a privileged web-application user account without user interaction.
Successful exploitation of the web vulnerability results in web-application or database management system compromise.
Request Method(s):
[+] GET
Vulnerable File(s):
[+] index.php
Vulnerable Parameter(s):
[+] error_codes
[+] subscriptions
[+] widget
[+] logins
Proof of Concept (PoC):
