CVE-2023-29413Network attack vector

Service interruption via unauthenticated SocketService access

Published Apr 18, 2023 · Updated Feb 5, 2025

Missing authentication in APC Easy UPS Online Monitoring Software 2.5-GA-01-22320 and earlier allows remote attackers to interrupt service. The SocketService module listens on UDP port 41222 by default and permits access to service functionality without authenticating the requester. No credentials or user interaction are required; the disclosed impact is limited to service availability, and public sources do not identify whether exploitation hangs or crashes the service.
