WordPress Plugin Vulnerabilities
Import WP < 2.4.6 - Admin+ Arbitrary File Upload to RCE
Description
The plugin does not validate the imported file in some cases, allowing high privilege users such as admin to upload arbitrary files (such as PHP), leading to RCE
Proof of Concept
Import a PHP file via an URL [Tools > Import WP > Add Importer (put any name, and post template) > Create Importer > Remote File (select any file type)], eg: https://example.com/info.php (content of info.php:<?php phpinfo();?>) Intercept the response to get the path of the file (via the file[src], eg: 06-2-info.php) and append that https://WP/wp-content/uploads/<year>/<month>, eg: https://WP/wp-content/uploads/2022/04/06-2-info.php
