CVE-2022-20830Network attack vector

Unauthenticated access via exposed SD-AVC GUI

Published Oct 10, 2022 · Updated Nov 1, 2024

Authentication bypass in Cisco Catalyst SD-WAN Manager allows remote attackers to access the SD-AVC GUI and view managed device names. The SD-AVC authentication mechanism exposes the GUI on self-managed cloud or local vManage installations without verifying credentials, returning SD-AVC logs and DNS server IP addresses. Reachability requires the GUI to be exposed, and the reported impact is read-only information disclosure without configuration changes or service interruption.
