asVereinbase <= 1.1.7 — Two-Factor Authentication Bypass

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under asVereinbase – Club & Member Management for WP.
• 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 1.1.8, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch asVereinbase – Club & Member Management for WP to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence.

The asVereinbase plugin for WordPress is vulnerable to Two-Factor Authentication Bypass in all versions up to, and including, 1.1.7. This is due to the authentication logic treating an empty stored credential value as a successful match against any supplied input, allowing the check to pass without a valid password or second factor. This makes it possible for unauthenticated attackers to log in as any registered user, including administrators, by exploiting the flawed credential check.
