CVE-2021-1421 (GCVE-0-2021-1421)

Vulnerability from cvelistv5 – Published: 2021-05-06 12:42 – Updated: 2024-11-08 23:18

Title

Cisco Enterprise NFV Infrastructure Software Command Injection Vulnerability

Summary

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.

Severity

7.8 (High)
