CVE-2026-86474

Estado: AplazadaAlta (7.7)—

The lack of TLS certificate validation when downloading firmware updates in VEO and VEO-XS Wi-Fi monitors, in versions prior to 01.48.001, allows an attacker to perform man-in-the-middle attacks on the update channel.

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:A (red adyacente) permite T1210. Falta validación TLS en descarga de firmware: ataque MITM (T1557) permite inyectar código malicioso (T1565.001 manipulación de firmware).

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.
