CVE-2021-22359

Estado: ModificadaAlta (7.5)—

There is a denial of service vulnerability in the verisions V200R005C00SPC500 of S5700 and V200R005C00SPC500 of S6700. An attacker could exploit this vulnerability by sending specific message to a targeted device. Due to insufficient input validation, successful exploit can cause the service abnormal.

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).
