CVE-2025-65856
Authentication bypass vulnerability in Xiongmai XM530 IP cameras on Firmware V5.00.R02.000807D8.10010.346624.S.ONVIF 21.06 allows unauthenticated remote attackers to access sensitive device information and live video streams. The ONVIF implementation fails to enforce authentication on 31 critical endpoints, enabling direct unauthorized video stream access.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 9.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.74%
- Percentil entre todas las CVEs puntuadas: 53
- Fecha de la puntuación: 5/10/2026
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.
