CVE-2025-8284Network attack vector

Unauthorized monitoring and control via missing authentication

Published Aug 8, 2025 · Updated Aug 8, 2025

Missing authentication in Packet Power EMX and Ethernet Gateway before 4.1.0 allows remote attackers to access control functions. The Monitoring and Control Web Interface defaults to no authentication and accepts unauthenticated requests for monitoring and control operations. Network access to the interface is sufficient to read monitoring data and manipulate device functions, without credentials or user interaction.
