CVE-2024-29941

Credential cloning via firmware-embedded default keys

Published May 6, 2024 · Updated Aug 2, 2024

Insecure key storage in Integrated Control Technology tSec firmware allows attackers to clone MIFARE and DESFire credentials. The firmware binary embeds the factory-default ICT encryption keys, allowing recovery of the secrets needed to generate arbitrary site-code and card-number combinations. Exposure is limited to deployments using the default ICT encryption, where cloned credentials can impersonate legitimate cards at affected readers.
