Technical Description
A hidden backdoor on PATLITE NH-FB Series devices with firmware version 1.45 or earlier, NH-FV Series devices with firmware version 1.10 or earlier, and NBM Series devices with firmware version 1.09 or earlier allow attackers to enable an SSH daemon via the "kankichi" or "kamiyo4" password to the _secret1.htm URI. Subsequently, the default password of root for the root account allows an attacker to conduct remote code execution and as a result take over the system.
Remediation
Check the references section for vendor advisories and patches from patlite. Update nbm-d88n_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
