WordPress Plugin Vulnerabilities
Simple School Staff Directory <= 1.1 - Admin+ Arbitrary File Upload
Description
The plugin does not validate uploaded logo pictures to ensure that are indeed images, allowing high privilege users such as admin to upload arbitrary file like PHP, leading to RCE
Proof of Concept
As admin, upload a PHP file via the Add Logo page of the plugin (https://example.com/wp-admin/options-general.php?page=simple-schools-staff-directory%2Fsi_main.php) The file will be located at https://example.com/wp-content/uploads/logos/<filename.php>
