Exploitation Probability (EPSS)

Low risk
0.16%

4th percentile - higher than 4% of all known CVEs

Summary

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.

Risk Assessment

An attacker can install malicious firmware on N-Tron devices, taking control of them. This can lead to permanent damage or takeover of network infrastructure.

Recommendation

Update N-Tron device firmware to a version that fixes the vulnerability. Disable unused SNMP/TFTP services and segment the industrial network.
