CVE-2026-107698

Estado: AnalizadaMedia (5.3)—

FFmpeg anterior a la 7.1.4 y 8.0.x anterior a la 8.0.2 contiene una vulnerabilidad de falsificación de solicitudes del lado del servidor (SSRF) en ff_rtsp_connect() en libavformat/rtsp.c, que sigue redirecciones RTSP 3xx sin validar la URL de Location. Los servidores RTSP maliciosos pueden redirigir FFmpeg a hosts y puertos internos con otros esquemas, eludiendo -protocol_whitelist, para sondear servicios de la red interna.

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.

UI:R indica interacción del usuario (reproducir contenido RTSP malicioso). SSRF en ff_rtsp_connect() permite proxificar tráfico a hosts internos (T1090). Reconocimiento de servicios internos (T1526) a través del seguimiento no validado de redirecciones 3xx.

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.
