CVE-2019-20461

Estado: AplazadaCrítica (9.8)—

An issue was discovered on Alecto IVM-100 2019-11-12 devices. The device uses a custom UDP protocol to start and control video and audio services. The protocol has been partially reverse engineered. Based upon the reverse engineering, no password or username is ever transferred over this protocol. Thus, one can set up the camera connection feed with only the encoded UID. It is possible to set up sessions with the camera over the Internet by using the encoded UID and the custom UDP protocol, because authentication happens at the client side.

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 permite T1190. Protocolo UDP sin autenticación real permite interceptación (T1557) y acceso a streams de video/audio (T1005) con solo UID codificado, sin credenciales.

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.
