Estado: AplazadaAlta (8.7)—

Multiple versions of Central Monitor CNS-6201 contain a NULL pointer dereference vulnerability. When processing a crafted certain UDP packet, the affected device may abnormally terminate.

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.
