Detection Guidance

The vulnerability in the iZooto WordPress plugin (versions up to 3.7.20) is due to missing authorization and authentication checks, allowing unauthenticated users to perform privileged actions.

To detect this vulnerability on your system, you should first identify if the affected plugin version is installed.

• Check the installed version of the iZooto plugin in your WordPress installation by running: wp plugin list | grep izooto-web-push
• If the version is less than or equal to 3.7.20, the plugin is vulnerable.

Since the vulnerability involves missing access control, you can attempt to access plugin functions or endpoints that require authorization without authentication to test if unauthorized actions are possible.

• Use curl or similar tools to send requests to plugin endpoints without authentication and observe if privileged actions are allowed.
• Example command: curl -X POST https://yourwebsite.com/wp-admin/admin-ajax.php?action=izooto_some_privileged_action

Note that no official patch is currently available, so detection mainly relies on version checking and testing unauthorized access attempts.
