CVE-2017-18862

Unauthenticated configuration and password disclosure

Published Apr 28, 2020 · Updated Aug 5, 2024

Authentication bypass in NETGEAR Web Managed Switches before 2017-05-11 allows remote attackers to read configuration files and passwords. NETGEAR has not published which management-interface operation fails to enforce authentication before returning these secrets. The attacker must share the switch's subnet; published evidence limits the consequence to disclosure of configuration data and passwords.
