CVE-2019-19106Network attack vector

Unauthorized data access via missing endpoint ACLs

Published Apr 22, 2020 · Updated Aug 5, 2024

Access-control bypass in ABB TG/S 3.2 and Busch-Jaeger 6186/11 gateways allows remote attackers to view or edit restricted data. The integrated web server omits ACL enforcement at multiple endpoints, including pages that display or change user profiles and application settings. Network access to the device is sufficient; exploitation requires no authentication and permits unauthorized disclosure and configuration changes.
