Vulnerability from github – Published: 2026-10-09 15:31 – Updated: 2026-10-09 15:31

Details

No authentication is required when updating firmware or bootloader, making it easy for malicious files to be pushed to the device. Additionally, anyone with the same software can scan a network for N-Tron devices and push/pull firmware without authenticating by using SNMP/TFTP.

Severity

7.1 (High)
