CVE-2019-16011

Authenticated root command execution via crafted CLI input

Published Apr 29, 2020 · Updated Nov 15, 2024

Command injection in the CLI of Cisco IOS XE SD-WAN Software before 17.2.1r allows local users to execute commands as root. The CLI utility fails to validate crafted input before passing it for command execution; Cisco has not identified the affected command or parser. An authenticated CLI account is required, and successful exploitation grants full root-level control of the affected router.
