CVE-2025-3461
Estado: AnalizadaCrítica (9.8)—
The Quantenna Wi-Fi chips ship with an unauthenticated telnet interface by default. This is an instance of CWE-306, "Missing Authentication for Critical Function," and is estimated as a CVSS 9.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). This issue affects Quantenna Wi-Fi chipset through version 8.0.0.28 of the latest SDK, and appears to be unpatched at the time of this CVE record's first publishing, though the vendor has released a best practices guide for implementors of this chipset.
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: 0.55%
- Percentil entre todas las CVEs puntuadas: 44
- 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
