CVE-2023-20168

Device reload via unchecked directed-request login string

Published Aug 23, 2023 · Updated Aug 2, 2024

Buffer overflow in Cisco NX-OS Software allows local users to reload affected devices through a crafted TACACS+ or RADIUS login string. The remote-authentication path fails to validate the crafted string before copying it into a bounded buffer during a directed-request login attempt. Exposure requires the TACACS+ or RADIUS directed-request option and either Telnet or console access; a reload can erase AAA configuration and block valid logins.
