CVE-2024-52329
📋 TL;DR
The ECOVACS HOME mobile app plugins for specific robot vacuum models fail to properly validate TLS certificates, allowing man-in-the-middle attackers to intercept and modify encrypted traffic. This vulnerability enables unauthenticated attackers to steal authentication tokens and potentially gain unauthorized access to robot controls. Users of affected ECOVACS robot models with the mobile app are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal authentication tokens, gain full control of robots, access home network devices, and potentially use robots as entry points for broader network compromise.
Likely Case
Attackers intercepting local network traffic could steal authentication tokens and control robots remotely, potentially accessing camera feeds or movement controls.
If Mitigated
With proper network segmentation and monitoring, impact is limited to robot functionality compromise without broader network access.
🎯 Exploit Status
Exploitation requires man-in-the-middle position on the same network; no public exploit code available but technical details are documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in advisory
Vendor Advisory: https://www.ecovacs.com/global/userhelp/dsa20241217001
Restart Required: No
Instructions:
1. Update ECOVACS HOME mobile app to latest version from official app store. 2. Ensure robot firmware is updated through the app. 3. Verify TLS certificate validation is functioning properly after update.
🔧 Temporary Workarounds
Network Segmentation
allIsolate robot devices on separate VLAN or network segment to limit attack surface
Disable Unnecessary Features
allTurn off remote access features if not required
🧯 If You Can't Patch
- Segment robot network from critical systems
- Monitor network traffic for unusual TLS certificate patterns
🔍 How to Verify
Check if Vulnerable:
Test TLS certificate validation by attempting man-in-the-middle interception on local network; check if app accepts invalid certificates.Check Version:
Check app version in ECOVACS HOME app settings; verify against latest version in app store.Verify Fix Applied:
After updating, test TLS certificate validation again; app should reject connections with invalid certificates.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts
- Multiple failed TLS handshakes
- Unexpected robot control commands
Network Indicators:
- Man-in-the-middle attack patterns
- Unusual TLS certificate validation failures
- Suspicious traffic interception on robot network
SIEM Query:
Search for network traffic patterns indicating TLS interception or certificate validation bypass on IoT device segments
