2. Security Patch Notes

The B628265 build addresses three critical Common Vulnerabilities and Exposures (CVEs) relevant to the embedded web server:

  1. CVE-2023-XXXX (Authentication Bypass): Resolved a logic error in the API token validation sequence that could allow unauthorized read access to device logs.
  2. TLS 1.3 Enforcement: Deprecated support for legacy TLS 1.0/1.1 protocols. B628265 enforces strict TLS 1.3 for all cloud-management dashboard communications.
  3. Secure Boot v2: The bootloader partition has been updated to prevent rollback attacks. Once B628265 is flashed, the hardware fuse will prevent the installation of firmware versions older than b628260.

Contact & escalation

For Linux (using terminal):

lsusb -v | grep -i "b628265"
sudo dmidecode | grep -A5 "Firmware"

For many serial devices, the firmware revision is also printed in the kernel ring buffer:
