CVE-2024-20399: Cisco NX-OS Vulnerability Under active Attack

There is a security flaw (CVE-2024-20399) in Cisco NX-OS Software that lets an attacker with local access execute commands as root on the affected device.

The vulnerability is caused by not properly checking the arguments used in certain configuration CLI commands. An attacker can take advantage of this vulnerability by inserting a specially-made input as an argument in one of the affected configuration CLI commands. If successful, the attacker could run any commands they want on the operating system with root privileges.

To successfully exploit this vulnerability on a Cisco NX-OS device, an attacker must have Administrator credentials. Cisco released updates to fix this issue. There are no other solutions available for this problem.
