CVE-2023-50126
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMissing encryption in the RFID tags of the Hozard alarm system (Alarmsysteem) v1.0 allow attackers to create a cloned tag via brief physical proximity to one of the original tags, which results in an attacker being able to bring the alarm system to a disarmed state.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Hozard alarm system v1.0 uses RFID tags without encryption, allowing attackers to clone tags via brief physical proximity. The cloned tags can then disarm the alarm system, bypassing authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Hozard Alarm System is deployedInventory your physical security devices and verify if the Hozard Alarm System is installed in your environmentAffected if The Hozard Alarm System is present in the environment
-
Verify the installed version is 1.0Check the device firmware version, system information, or product labeling to confirm the exact version. Compare against the affected version range: 1.0Affected if The version is exactly 1.0
-
Confirm RFID feature is enabledAccess the alarm system configuration panel or settings and check whether the RFID tag functionality is activated or in useAffected if RFID functionality is enabled and operational
-
Inspect RFID tag configuration for encryptionExamine the RFID tag settings or documentation to determine whether the tags are configured to use encrypted communication. Look for encryption-related options or check if the tags support encryptionAffected if RFID tags are configured without encryption or use unencrypted communication protocols
You are affected if you have a Hozard Alarm System version 1.0 with RFID functionality enabled and the tags are operating without encryption.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement encrypted RFID communication or migrate to a more secure RFID protocol that supports authentication and prevents cloning. Consider replacing existing tags with encrypted versions if current hardware lacks cryptographic capabilities.
