User Access Manager <= 2.3.12 — Authenticated (Subscriber+) SQL Injection

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under User Access Manager.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 2.3.13, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch User Access Manager to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Nox Axter.

The User Access Manager plugin for WordPress is vulnerable to Second-Order SQL Injection via the 'id' parameter of the wp_ajax_save-attachment-compat AJAX action in versions up to, and including, 2.3.12. This is due to insufficient validation on the objectId value stored in the saveAjaxAttachmentData() function and subsequent unparameterized concatenation in the addQueryExcludedPostFilter() function — the stored value is later retrieved from the database and used as an array key, then directly imploded into a SQL NOT IN() clause without integer casting or prepared statements. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
