Summary
generated automatically from NVD dataSnap One WattBox 800 and 820 series firmware prior to 2.10.0.0 exposes undisclosed diagnostic HTTP endpoints that authenticate using only the device MAC address and service tag. Both values are printed in plaintext on the physical device label, so anyone who sees the label or documentation containing them can authenticate and run arbitrary commands as root on the device (CWE-798). The flaw is rated CRITICAL with a CVSS v3.1 score of 9.8.
