CVE-2023-51571Network attack vector

Unauthenticated service interruption via SocketService requests

Published Apr 1, 2024 · Updated Aug 27, 2024

Missing authentication in SocketService in Voltronic Power ViewPower Pro 2.0-22165 allows remote attackers to interrupt the service. SocketService listens on UDP port 41222 by default and exposes functionality without authenticating received requests. Any network-reachable unauthenticated attacker can trigger the availability-only condition; the public advisory does not identify the exact message or whether the service hangs or crashes.
