Support Genix <= 1.4.52 — Authenticated (Subscriber+) Authentication Bypass to Administrator Account Takeover via 'p' Parameter Forged Guest Token

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Support Genix – Helpdesk, AI Chatbot, Knowledge Base & Customer Support Ticketing System.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 1.4.53, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Support Genix – Helpdesk, AI Chatbot, Knowledge Base & Customer Support Ticketing System to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Supakiad S. (m3ez).

The Support Genix – Helpdesk, AI Chatbot, Knowledge Base & Customer Support Ticketing System plugin for WordPress is vulnerable to Authentication Bypass leading to Administrator Account Takeover in all versions up to, and including, 1.4.52 via the `guest_ticket_login()` function and its `p` parameter. This is due to the site-wide AES-256-CBC encryption key being derived from only three two-digit `wp_rand(10, 99)` values and a Unix timestamp via `md5()` — yielding approximately 19.5 bits of entropy — combined with a deterministic IV derived from the password, no authentication tag on the ciphertext, and no capability check, nonce, or session validation on the publicly reachable `/sgnix/?p=<token>` endpoint. This makes it possible for authenticated attackers, with subscriber-level access and above, who can obtain a single legitimate guest ticket token as a known-plaintext oracle and bound the plugin activation timestamp, to exhaust the ~729,000-candidate keyspace entirely offline, recover the site-wide encryption key, and forge a self-consistent `{ticket_id, ticket_user}` token targeting any administrator-owned ticket. Submitting the forged token to the unprotected endpoint causes `wp_set_auth_cookie()` to be called for that administrator, granting the attacker full administrative access to the WordPress site.
