CVE-2026-77532

Estado: AplazadaCrítica (9.6)—

A malicious actor with access to an adjacent network could exploit a Buffer Overflow vulnerability found in a DHCPv6-enabled EdgeMAX EdgeSwitch to initiate a Remote Code Execution on such device.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Puntuación base: 9.6

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.41%
Percentil entre todas las CVEs puntuadas: 33
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).

Vector AV:A (red adyacente) sin privilegios previos y CWE-122 (buffer overflow) en servicio DHCPv6 remotamente accesible justifican T1210. RCE en dispositivo de red permite ejecución de comandos (T1059) y potencial escalada de privilegios en el switch (T1068).

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.
