CVE-2024-44754
📋 TL;DR
This vulnerability allows physically proximate attackers to extract cryptographic keys from the internal flash memory of Minut M2 devices running firmware version #15142. Attackers can then use these keys to inject modified firmware into other Minut M2 products via USB. Only Minut M2 devices with the specific vulnerable firmware version are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers gain complete control over Minut M2 devices, enabling firmware manipulation, data theft, device repurposing for malicious activities, or creation of a botnet of compromised devices.
Likely Case
Local attackers with physical access compromise individual devices to bypass security controls, extract sensitive data, or install unauthorized firmware modifications.
If Mitigated
With proper physical security controls preventing unauthorized access to USB ports, the vulnerability cannot be exploited despite its presence in firmware.
🎯 Exploit Status
Exploitation requires physical access to USB port and specialized hardware/knowledge for flash memory extraction and firmware modification, but no authentication is needed once physical access is obtained.
🛠️ Fix & Mitigation

🔧 Temporary Workarounds
Physical Access Control
allPrevent unauthorized physical access to device USB ports
Disable Unused USB Ports
allPhysically disable or block USB ports if device functionality doesn't require them
🧯 If You Can't Patch
- Implement strict physical security controls to prevent unauthorized access to devices
- Isolate affected devices in secure locations with limited physical access
🔍 How to Verify
Check if Vulnerable:
Check firmware version in device settings or via Minut app - if version is exactly #15142, device is vulnerableCheck Version:
Check via Minut mobile app device settings or device web interface if availableVerify Fix Applied:
Confirm firmware version has changed from #15142 to a newer version after update📡 Detection & Monitoring
