Am I affected?

W3 Total Cache w3-total-cache

  1. Affected≤ 0.9.4
  2. Patched in0.9.4.1

Update to 0.9.4.1 or newer.

You are affected if you run ≤ 0.9.4. Version 0.9.4.1 and later are not affected by this issue.

  • Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under W3 Total Cache.
  • No admin access? Run a passive check of your site. It reads public files only.
  • No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

  1. Update to version 0.9.4.1, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch W3 Total Cache to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Mazin Ahmed.

The W3 Total Cache plugin before 0.9.4.1 for WordPress does not properly handle empty nonces, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and hijack the authentication of administrators for requests that change the mobile site redirect URI via the mobile_groups[*][redirect] parameter and an empty _wpnonce parameter in the w3tc_mobile page to wp-admin/admin.php.
