CVE-2026-41286

Estado: ModificadaAlta (7.1)—

Stack-based Buffer Overflow vulnerability in the WatchGuard Agent discovery service on Windows allows Overflow Buffers. An unauthenticated attacker on the same local network could exploit this vulnerability to crash the agent service.

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 servicio de red accesible desde red adyacente (AV:A) sin autenticación. CWE-121 permite inyección de código pero el texto enfatiza crash (DoS). T1210 por acceso a red adyacente; impacto T1499.004 (service exhaustion) por negación de servicio.

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.
