CVE-2025-34434

Estado: ModificadaCrítica (9.3)—

AVideo versions prior to 20.1 with the ImageGallery plugin enabled is vulnerable to unauthenticated file upload and deletion. Plugin endpoints responsible for managing gallery images fail to enforce authentication checks and do not validate ownership, allowing unauthenticated attackers to upload or delete images associated with any image-based video.

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.

AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). La falta de validación de autenticación permite acceso no autorizado (T1078), y la capacidad de subir/eliminar archivos sin verificación constituye manipulación de datos (T1565.002).

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.
