CVE-2025-65824
📋 TL;DR
An unauthenticated attacker within Bluetooth range can perform unauthorized firmware upgrades on Meatmeet devices via BLE, leading to complete device takeover. This affects all Meatmeet devices that don't validate firmware updates, allowing attackers to execute arbitrary code and lock out legitimate users.
💻 Affected Systems
- Meatmeet devices
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise with persistent attacker-controlled firmware, enabling surveillance, data theft, or device bricking across all vulnerable devices in physical proximity.
Likely Case
Attacker overwrites firmware to disable device functionality or install malicious code for botnet participation, causing service disruption for victims.
If Mitigated
With proper firmware validation and authentication, impact is limited to denial of service attempts that fail due to security checks.
🎯 Exploit Status
Public proof-of-concept available on GitHub. Exploitation requires BLE communication tools but no authentication or special privileges.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
1. Check vendor website for firmware updates 2. Download official firmware 3. Apply update via authorized method 4. Verify firmware integrity
🔧 Temporary Workarounds
Disable BLE when not in use
allTurn off Bluetooth Low Energy functionality to prevent unauthorized access
Device-specific command to disable BLE
Physical access control
allRestrict physical access to devices to prevent proximity-based attacks
🧯 If You Can't Patch
- Isolate devices in secure physical locations with limited access
- Implement network segmentation to limit potential lateral movement if compromised
🔍 How to Verify
Check if Vulnerable:
Attempt BLE connection to device and check if firmware upgrade can be initiated without authenticationCheck Version:
Device-specific command to display firmware versionVerify Fix Applied:
Verify firmware signature validation is enforced and BLE requires authentication for firmware updates📡 Detection & Monitoring
Log Indicators:
- Unexpected firmware update attempts
- BLE connection attempts from unauthorized devices
- Firmware version changes without authorized updates
Network Indicators:
- Unusual BLE traffic patterns
- Firmware download attempts via BLE
