CVE-2024-0568
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 · uneditedCWE-287: Improper Authentication vulnerability exists that could cause unauthorized tampering of device configuration over NFC communication.
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 confidenceThis is an improper authentication vulnerability (CWE-287) in NFC communication that allows unauthorized tampering of device configuration. The vulnerability likely involves weaknesses in the authentication mechanism used during NFC transactions, potentially allowing attackers to bypass or circumvent authentication checks when communicating with devices over NFC.

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.
-
Identify device modelCheck the device firmware or hardware model identification (e.g., via deviceinfo API, system settings, or physical label). Look for model numbers Rmnf22tb30 or Renf22r2mmw.Affected if Device model matches Se Rmnf22tb30 or Se Renf22r2mmw
-
Locate NFC configuration interfaceAccess device configuration panels, typically found in system settings under Wireless/NFC or Security settings. Check for NFC-specific configuration files if CLI access is available.Affected if NFC configuration interface or NFC service is present on the device
-
Verify NFC is enabledInspect NFC status in device settings or query NFC service state via system commands (e.g., 'getprop' on Android, NFC status menus, or device management console).Affected if NFC is currently enabled and operational on the device
-
Examine NFC authentication settingsReview NFC-related security settings in the device configuration, specifically looking for authentication enforcement, credential requirements, or session security configurations.Affected if NFC authentication can be bypassed, disabled, or is not enforced for configuration changes
You are affected if your device is a Se Rmnf22tb30 or Se Renf22r2mmw model with NFC enabled, regardless of version, since all firmware versions of these products are vulnerable.

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 proper authentication mechanisms for NFC communications, including strong credential validation, session token management, and cryptographic verification of commands before allowing configuration changes.
