The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a Cisco NX-OS Command Injection Vulnerability, tracked as CVE-2024-20399, to its Known Exploited Vulnerabilities (KEV) catalog.
This week, Cisco addressed an NX-OS zero-day, tracked as CVE-2024-20399 (CVSS score of 6.0), that the China-linked group Velvet Ant exploited to deploy previously unknown malware as root on vulnerable switches.
The flaw resides in the CLI of Cisco NX-OS Software, an authenticated, local attacker can exploit the flaw to execute arbitrary commands as root on the underlying operating system of an affected device.
“This vulnerability is due to insufficient validation of arguments that are passed to specific configuration CLI commands. An attacker could exploit this vulnerability by including crafted input as the argument of an affected configuration CLI command.” reads the advisory published by Cisco. “A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with the privileges of root.”
