How can this vulnerability be detected on my network or system? Can you suggest some commands?

This vulnerability involves the Slider Revolution WordPress plugin versions 7.0.0 to 7.0.14 and can be exploited via the 'slider.get.full' AJAX action by authenticated users with Contributor-level access or higher.

To detect if your system is vulnerable, you should first verify the version of the Slider Revolution plugin installed on your WordPress site. If it falls within the affected range, the site is potentially vulnerable.

You can check the plugin version by running the following command on your server (assuming you have shell access and the WordPress installation path):

• grep 'Version:' wp-content/plugins/revslider/revslider.php

Alternatively, you can query the plugin version via WP-CLI:

• wp plugin get revslider --field=version

To detect exploitation attempts on your network, monitor HTTP requests for the AJAX action 'slider.get.full' originating from authenticated users. For example, using command-line tools like grep on your web server logs:

• grep 'action=slider.get.full' /var/log/apache2/access.log
• grep 'action=slider.get.full' /var/log/nginx/access.log

Look for requests that include this AJAX action and check if they come from users with Contributor-level or higher privileges.
