CVE-2023-20056

Authenticated device reload via unvalidated CLI input

Published Mar 23, 2023 · Updated Oct 25, 2024

Command injection in the management CLI of Cisco Aironet Access Point Software allows local users to trigger a device reload. The affected CLI command does not sufficiently validate user-supplied command input before processing it, permitting OS command injection. The attacker must authenticate locally to the device; successful exploitation spontaneously reloads the access point and interrupts service.
