Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
Use of a deterministic credential generation algorithm in /ftl/bin/calc_f2 in Small Cell Sercomm SCE4255W (FreedomFi Englewood) firmware before DG3934v3@2308041842 allows remote attackers to derive valid administrative/root credentials from the device's MAC address, enabling authentication bypass and full device access.
