CVE-2019-1726
"Cisco NX-OS Insufficient Argument Validation Authentication Bypass"
Description
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to access internal services that should be restricted on an affected device, such as the NX-API. The vulnerability is due to insufficient validation of arguments passed to a certain CLI command.
