CVE-2021-1421

Estado: ModificadaAlta (7.8)—

A vulnerability in Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to perform a command injection attack on an affected device. The vulnerability is due to insufficient validation of user-supplied input to a configuration command. An attacker could exploit this vulnerability by including malicious input during the execution of this command. A successful exploit could allow a non-privileged attacker authenticated in the restricted CLI to execute arbitrary commands on the underlying operating system (OS) with root privileges.

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).
