CVE-2025-65825

4.6 MEDIUM

📋 TL;DR

The Meatmeet device's firmware lacks encryption, allowing attackers with physical access to extract Wi-Fi credentials via UART interface. This exposes current and previous Wi-Fi network credentials, potentially enabling unauthorized network access. All Meatmeet device owners are affected.

💻 Affected Systems

Products:
  • Meatmeet device
Versions: All versions with unencrypted firmware
Operating Systems: Embedded firmware
Default Config Vulnerable: ⚠️ Yes
Notes: Requires physical access to device and UART connection capability

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attacker gains persistent access to victim's Wi-Fi network, enabling further attacks on connected devices, data interception, or network compromise.

🟠

Likely Case

Local attacker extracts Wi-Fi credentials and gains unauthorized network access, potentially monitoring traffic or accessing shared resources.

🟢

If Mitigated

With proper physical security controls, risk is limited to authorized personnel with device access.

🌐 Internet-Facing: LOW
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires physical disassembly and UART connection, but process is documented in public references

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None known

Restart Required: No

Instructions:

No official patch available. Contact vendor for firmware update with encryption enabled.

🔧 Temporary Workarounds

Enable firmware encryption

all

Recompile firmware with flash encryption enabled to protect NVS partition

Requires firmware recompilation with CONFIG_SECURE_FLASH_ENC_ENABLED=y

🧯 If You Can't Patch

  • Implement strict physical security controls for device location
  • Regularly rotate Wi-Fi credentials and monitor network for unauthorized access

🔍 How to Verify

Check if Vulnerable:

Check if esptool.py can read NVS partition without encryption key: esptool.py --port /dev/ttyUSB0 read_flash 0x9000 0x6000 nvs.bin

Check Version:

No standard version check command available for embedded firmware

Verify Fix Applied:

Attempt to read NVS partition with esptool.py - should fail with encryption error if fixed

📡 Detection & Monitoring

Log Indicators:

  • Unexpected device disassembly or physical tampering

Network Indicators:

  • Unauthorized MAC addresses on Wi-Fi network
  • Unexpected network traffic patterns

SIEM Query:

Search for failed authentication attempts from new devices on Wi-Fi network
