Grand Job <= 1.2.1 — Unauthenticated Privilege Escalation via Account Takeover

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Grand Job.
• 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. No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Grand Job to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence.

The Grand Job plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.2.1. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.
