Prior-user identity disclosure via NFC card sequencing
Published Oct 30, 2025 · Updated Oct 30, 2025
Information disclosure in HP Card Readers B Models before 2.9 allows physically proximate attackers to inherit a prior user's identity. During sequential 13.56 MHz reads, the reader associates a subsequent dynamic-CSN card or nearby NFC device with identity data retained from the initial static-CSN card. Exploitation requires physical access during the card sequence, and the scenario does not apply when Secure Credentials such as a PIN are configured.
