CVE-2020-22657Network attack vector

Unauthenticated management access via web GUI login bypass

Published Jan 20, 2023 · Updated Apr 3, 2025

Improper authentication in affected RUCKUS controllers and access points allows remote attackers to gain unauthorized management access. Public records identify the web GUI login path as the affected locus but do not disclose the request, credential check, or validation error that accepts an unauthenticated session. The interface must be network-reachable; exploitation bypasses credentials and grants management access, while no availability impact is reported.
