NinjaScanner – Virus & Malware scan <= 3.2.5 — Authenticated (Administrator+) Arbitrary File Deletion

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under NinjaScanner – Virus & Malware scan.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 3.2.6, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch NinjaScanner – Virus & Malware scan to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Jonas Benjamin Friedli.

The NinjaScanner – Virus & Malware scan plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'nscan_ajax_quarantine' and 'nscan_quarantine_select' functions in all versions up to, and including, 3.2.5. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, including files outside the WordPress root directory.
