CVE-2025-65822
📋 TL;DR
This vulnerability allows attackers with physical access to an ESP32-powered Meatmeet Pro device to connect via JTAG and flash malicious firmware. The attack can disable device functionality and potentially grant unauthorized access to the victim's Wi-Fi network. Only users of affected Meatmeet Pro devices are impacted.
💻 Affected Systems
- Meatmeet Pro with ESP32 SoC
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attacker gains persistent access to victim's Wi-Fi network, installs backdoors, and completely compromises the device for further attacks.
Likely Case
Device functionality is disrupted, requiring hardware replacement, and attacker may access the local network temporarily.
If Mitigated
With physical security controls, impact is limited to device tampering without network access.
🎯 Exploit Status
Exploitation requires physical access and basic JTAG hardware/tools.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: N/A
Vendor Advisory: N/A
Restart Required: No
Instructions:
No official patch available. Requires firmware update with JTAG disabled in production builds.
🔧 Temporary Workarounds
Disable JTAG in firmware
allModify ESP32 firmware to disable JTAG interface before production deployment
In menuconfig: Component config > ESP System Settings > JTAG Adapter > Disable
Physical tamper protection
allApply epoxy or physical seals to prevent access to JTAG pins
🧯 If You Can't Patch
- Restrict physical access to devices through secure mounting/enclosures
- Segment network to isolate Meatmeet Pro devices from critical systems
🔍 How to Verify
Check if Vulnerable:
Check if JTAG pins are accessible on device PCB and attempt connection with JTAG debuggerCheck Version:
