CVE-2025-12995
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 · uneditedMedtronic CareLink Network allows an unauthenticated remote attacker to perform a brute force attack on an API endpoint that could be used to determine a valid password under certain circumstances. This issue affects CareLink Network: before December 4, 2025.
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 confidenceMedtronic CareLink Network contains an unauthenticated API endpoint that allows remote attackers to perform brute force attacks to determine valid user passwords. The vulnerability lacks adequate rate limiting or account lockout protections, enabling automated password guessing.

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 the CareLink Network versionLocate the installed version of Medtronic CareLink Network in the system documentation, administration console, or version information panelAffected if The installed version is earlier than 2025-12-04
-
Verify API endpoint accessibilityConfirm whether unauthenticated API endpoints for the CareLink Network are exposed to the network or internetAffected if API endpoints are accessible without authentication from external or untrusted networks
-
Check for rate limiting on API endpointsReview API gateway or web server configuration to determine if rate limiting is configured on CareLink Network endpointsAffected if Rate limiting is not implemented or is disabled on the API endpoints
-
Confirm account lockout policy statusInspect the authentication or security settings for the CareLink Network to verify if account lockout after failed login attempts is enabledAffected if Account lockout protection is disabled or not configured for user accounts
You are affected if the CareLink Network version is earlier than 2025-12-04 and unauthenticated API endpoints are accessible without rate limiting or account lockout protections in place.
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.
dbcve · scoped2025-12-04
Apply the vendor patch released December 4, 2025. Implement rate limiting, account lockout policies, and consider multi-factor authentication on affected API endpoints.
CareLink Network version 2025-12-04 or later
- Identify the current CareLink Network version currently deployed
- Contact Medtronic technical support to obtain and apply the updated version (2025-12-04 or later)
- After upgrading to version 2025-12-04 or newer, verify that the API endpoint no longer allows unlimited authentication attempts
- Confirm the fix by testing that account lockout or rate limiting is now enforced after multiple failed login attempts
