CVE-2026-33485

Estado: AnalizadaAlta (7.5)—

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the RTMP `on_publish` callback at `plugin/Live/on_publish.php` is accessible without authentication. The `$_POST['name']` parameter (stream key) is interpolated directly into SQL queries in two locations — `LiveTransmitionHistory::getLatest()` and `LiveTransmition::keyExists()` — without parameterized binding or escaping. An unauthenticated attacker can exploit time-based blind SQL injection to extract all database contents including user password hashes, email addresses, and other sensitive data. Commit af59eade82de645b20183cc3d74467a7eac76549 contains a patch.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

RTMP callback sin autenticación (AV:N, PR:N, UI:N) en aplicación expuesta; inyección SQL ciega extrae datos sensibles (contraseñas, emails). La manipulación de datos es secundaria porque el vector no indica C:H/I:H conjunto.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
