Unauthenticated denial of service via NetworkServlet actions
Published Jul 22, 2022 · Updated Apr 16, 2025
Missing authentication in Advantech iView before 5.7.04.6469 allows remote attackers to cause denial of service through NetworkServlet. The endpoint on TCP port 8080 exposes clearDatabase, removeDevices, and removeSegment functionality without checking authentication. A network-reachable attacker needs no account to invoke these state-changing operations and interrupt the iView service.
