Leer descripción completaMostrar menos

Attackers can bypass authentication by including specially crafted text in the request URL or message header, and then inject arbitrary malicious commands into some fields related to ACL access control list and user group functions and execute to obtain the highest ROOT privileges of remote devices, thereby completely taking over the remote target devices.

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).
