Technical details
This vulnerability is a hard-coded password weakness (CWE-259) where a static credential is embedded in the firmware of the CPTrans-ME-X device. An attacker with network access to the administrative port can authenticate using this embedded password without authorization. The vulnerability has a CVSS 3.0 score of 9.8 (network-accessible, no authentication required, and leads to high impact on confidentiality, integrity, and availability). Firmware versions prior to 1.8.1.17 are affected. The vendor released a firmware update via FOTA (Firmware Over-The-Air) in April 2026 that disables the administrative port in initial configuration and restricts available commands.
