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."}],"title":"Support Genix <= 1.4.52 - Authenticated (Subscriber+) Authentication Bypass to Administrator Account Takeover via 'p' Parameter Forged Guest Token","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/188f7c1d-e8ad-4114-9aa4-c3e8b51c5f2c?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/modules/Apbd_wps_settings.php#L748"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/modules/Apbd_wps_settings.php#L152"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/libs/Apbd_Wps_EncryptionLib.php#L27"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/core/secondary_helper.php#L754"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/models/database/Mapbd_wps_ticket.php#L457"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/modules/Apbd_wps_settings.php#L748"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/modules/Apbd_wps_settings.php#L152"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/libs/Apbd_Wps_EncryptionLib.php#L27"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/core/secondary_helper.php#L754"},{"url":"https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/models/database/Mapbd_wps_ticket.php#L457"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3668350%40support-genix-lite&new=3668350%40support-genix-lite"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-287 Improper Authentication","cweId":"CWE-287","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Supakiad S.
