CVE-2026-33293

Estado: AnalizadaAlta (8.1)—

WWBN AVideo is an open source video platform. Prior to version 26.0, the `deleteDump` parameter in `plugin/CloneSite/cloneServer.json.php` is passed directly to `unlink()` without any path sanitization. An attacker with valid clone credentials can use path traversal sequences (e.g., `../../`) to delete arbitrary files on the server, including critical application files such as `configuration.php`, causing complete denial of service or enabling further attacks by removing security-critical files. Version 26.0 fixes the issue.

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.

Vulnerabilidad de path traversal (CWE-22) en servicio remoto que requiere autenticación (PR:L), permitiendo borrar archivos críticos; impacto primario es negación de servicio (A:H) y secundario manipulación de datos al alterar configuración.

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.
