DESCRIPTION
|
||
====================
|
||
|
||
In a recent security research, a privilege scalation web vulnerability has been detected in the WordPress Ultimate Product Catalogue Plugin <=v3.8.1.
|
||
The vulnerability allows remote attackers to take over control of the Ultimate Product Catalogue Plugin administration page if the plugin ispremium version and the remote attacker have an especific account (contributor|editor|author).
|
||
The privilege scalation web vulnerability is located in the <upc-plugin-path>/Functions/Update_Admin-Databases.php` file.
|
||
Remote attackers are able to request crafted data of the POST method request with the vulnerable ´acces_role´ parameter.
|
||
|
||
The security risk of the privilege scalation web vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 8.6.
|
||
Exploitation of the privilege scalation vulnerability requires low user interaction and low privilege web-application user account.
|
||
Successful exploitation of the privilege scalation web vulnerability results in web aplication compromise.
|
||
|
||
For security demostration I made a prof of concept to show the vulnerability logged in as a contributor user.
