CVE-2025-13455
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 · uneditedA vulnerability was reported in ThinkPlus configuration software that could allow a local authenticated user to bypass ThinkPlus device authentication and enroll an untrusted fingerprint.
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 · high confidenceThinkPlus configuration software contains a local authentication bypass vulnerability allowing an authenticated low-privilege user to bypass device authentication controls and enroll an untrusted fingerprint. This is a local attack requiring authenticated access, where the enrollment validation logic fails to properly verify the user's identity before accepting fingerprint data.

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 ThinkPlus software installationSearch for ThinkPlus configuration software on the system - look for application files, services, or drivers named ThinkPlus, Fu100, Fu200, Tu800, or Tsd303Affected if ThinkPlus configuration software is installed on the system
-
Identify ThinkPlus device modelCheck for connected USB or attached ThinkPlus fingerprint devices - Fu100, Fu200, Tu800, or Tsd303 modelsAffected if Any of the affected device models (Fu100, Fu200, Tu800, Tsd303) are connected or installed
-
Check for existing fingerprint enrollmentsReview the ThinkPlus configuration software or system for any enrolled fingerprints - look for enrollment records, user-fingerprint mappings, or fingerprint templates stored on the systemAffected if Fingerprints have been enrolled through the ThinkPlus software
-
Review enrollment audit logsExamine system event logs, application logs, or security logs for fingerprint enrollment events performed by users - look for enrollment timestamps, user accounts, and enrollment success/failure recordsAffected if Fingerprint enrollment events exist in logs, especially from low-privilege user accounts
-
Verify user access patternsCheck which user accounts have access to the ThinkPlus configuration software and fingerprint enrollment features - review permissions, user groups, and authentication contextsAffected if Low-privilege or standard user accounts have access to fingerprint enrollment functionality
If ThinkPlus configuration software with any of the affected device models (Fu100, Fu200, Tu800, Tsd303) is present and fingerprint enrollment is accessible to authenticated users, the environment is affected by this vulnerability.

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 dataApply vendor-supplied patch for ThinkPlus configuration software when available; until then, restrict physical and console access to systems running this software and monitor for unauthorized fingerprint enrollment events.
