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 · unedited
Buffer Overflow vulnerability in Neat Board NFC v.1.20240620.0015 allows a physically proximate attackers to escalate privileges via a crafted payload to the password field

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 confidence

A buffer overflow vulnerability exists in the password field of Neat Board NFC version 1.20240620.0015. A physically proximate attacker can exploit this by sending a crafted payload to the password field, causing a buffer overflow that leads to privilege escalation.

MitigationApply vendor-supplied patch/firmware update when available. Until then, enforce strict physical access controls to the device and consider network isolation. Validate that password input fields properly bounds-check before processing.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Neat Board NFC device
    Locate and confirm the Neat Board NFC hardware unit in your environment. Check physical labels, management console, or inventory records for the device identifier.
    Affected if The device is a Neat Board NFC unit
  2. Check the installed firmware version
    Access the device admin interface or system settings and locate the firmware version information. Compare it against the affected version 1.20240620.0015.
    Affected if The firmware version is exactly 1.20240620.0015
  3. Verify physical access controls
    Assess whether untrusted or unauthorized individuals can physically access the Neat Board NFC device. Check if the device is in a secured, restricted area.
    Affected if The device is physically accessible to unauthorized or untrusted persons
  4. Confirm password feature is enabled
    Check if the password authentication feature on the Neat Board NFC is configured or active. Review device settings or user authentication configurations.
    Affected if Password authentication is enabled on the device

You are affected if you have a Neat Board NFC running firmware version 1.20240620.0015 with password authentication enabled and the device is physically accessible to untrusted users.
