CVE-2026-3823

Estado: ModificadaCrítica (9.3)—

EHG2408 series switch developed by Atop Technologies has a Stack-based Buffer Overflow vulnerability, allowing unauthenticated remote attackers to control the program's execution flow and execute arbitrary code.

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.

Buffer overflow en switch de red accesible remotamente sin autenticación (AV:N, PR:N, UI:N) permite ejecución arbitraria de código; CWE-121/787 confirman desbordamiento de pila.

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.
