CVE-2023-38096Network attack vector

Authentication bypass via flawed interceptor access check

Published May 3, 2024 · Updated Sep 18, 2024

Authentication bypass in NETGEAR ProSAFE Network Management System before 1.7.0.20 allows remote attackers to access protected functions. The MyHandlerInterceptor class performs an improper authentication check, allowing unauthenticated requests through the web access-control path. No account or user interaction is required, and successful exploitation reaches functions intended for authenticated users.
