CVE-2022-20924Network attack vector

Authenticated device reload via crafted SNMP request

Published Nov 10, 2022 · Updated Aug 3, 2024

Improper exceptional-condition handling in Cisco ASA and FTD Software allows remote authenticated users to reload devices through SNMP. The SNMP request handler inadequately validates a crafted request and enters an exceptional condition that reloads the affected device. Remote SNMP management must be enabled, and successful exploitation interrupts firewall service by forcing a device reload.
