NewCVE-2025-25201 (opens in a new tab)How to fix?
Upgrade Nitrokey/nitrokey-3-firmware to version 1.8.1 or higher.
Overview
Affected versions of this package are vulnerable to Improper Authentication due to improper validation of authentication keys with PIV enabled prior to 1.8.0. The PIV functionality could accept invalid keys to authenticate the admin key. This compromises the integrity of PIV data objects, allowing an attacker without the proper administration key to generate new keys and overwrite certificates. However, the attacker would not be able to extract existing private data or access cryptographic operations requiring PIN-based authentication.
