27th percentile - higher than 27% of all known CVEs

Summary

The door access control on a Norwegian Cruise Line asset grants entry based only on the credential's static 7-byte UID stored on an NTAG212 NFC chip. A UID is a manufacturer serial number sent in the clear on every read and is not intended to be secret or to authenticate the holder.

Risk Assessment

Since the UID is not secret and there is no challenge-response capability, the credential can be easily copied, allowing unauthorized individuals to gain access to protected areas.

Recommendation

Implement cryptographic authentication (e.g., challenge-response) instead of relying solely on the UID.

Original NVD description (English source)

The door access control on a Norwegian Cruise Line asset grants entry based only on the credential's static 7-byte UID stored on an NTAG212 NFC chip. A UID is a manufacturer serial number sent in the clear on every read and is not intended to be secret or to authenticate the holder. Validating on the UID of the NTAG212 NFC chip alone is identification, not authentication, and the credential has no challenge-response capability that would resist copying.
