CVE-2026-8806

Estado: AplazadaAlta (8.7)—

Expected Behavior Violation vulnerability in Mitsubishi Electric MELSEC iQ-F Series FX5-ENET/IP Ethernet Module FX5-ENET/IP all versions allows a remote attacker to cause a denial-of-service (DoS) condition in the affected product by continuously sending a large number of communication packets to the Ethernet port of the product in a short period of time, increasing the processing load of the product, preventing the internal anomaly-detection processing from being performed, and causing the communication function to stop.

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
