Detailsinfo

A vulnerability has been found in Norwegian Cruise Line door access control (unknown version) and classified as problematic. Affected by this vulnerability is an unknown code block. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. The impact remains unknown. The summary by CVE is:

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.

The advisory is shared at kb.cert.org. This vulnerability is known as CVE-2026-75907 since 08/18/2026. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.
