CVE-2025-12995
📋 TL;DR
Medtronic CareLink Network has an API endpoint vulnerable to unauthenticated brute force attacks, allowing attackers to potentially discover valid passwords. This affects all CareLink Network systems before December 4, 2025. The vulnerability enables unauthorized access to medical device management systems.
💻 Affected Systems
- Medtronic CareLink Network
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of medical device management systems, allowing unauthorized control of patient-connected devices, data exfiltration, or disruption of critical healthcare services.
Likely Case
Unauthorized access to patient data, configuration changes to medical devices, or disruption of device management operations.
If Mitigated
Failed login attempts detected and blocked before successful compromise, with no actual system access achieved.
🎯 Exploit Status
Attack requires no authentication and can be performed remotely using standard brute force tools.
