CVE-2024-52327
📋 TL;DR
This vulnerability allows authenticated attackers to bypass the PIN protection on ECOVACS robot lawnmowers and vacuums, enabling unauthorized access to live video feeds. It affects users of ECOVACS cloud-connected robotic devices who rely on PIN protection for video privacy. The bypass occurs through the cloud service interface rather than local device access.
💻 Affected Systems
- ECOVACS robot lawnmowers
- ECOVACS robot vacuums with camera functionality

⚠️ Risk & Real-World Impact
Worst Case
Attackers could monitor private spaces via live video feeds, potentially capturing sensitive activities, personal information, or home layouts for physical security threats.
Likely Case
Unauthorized viewing of indoor/outdoor spaces where ECOVACS devices operate, violating privacy expectations of users who enabled PIN protection.
If Mitigated
Limited to authenticated users only, preventing completely anonymous attacks but still allowing account-compromised attackers to bypass additional security layers.
🎯 Exploit Status
Exploitation requires authenticated access to the cloud service. Public research presentations demonstrate the bypass technique.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Cloud service updates implemented December 2024
Vendor Advisory: https://www.ecovacs.com/global/userhelp/dsa20241217002
Restart Required: No
Instructions:
1. Ensure ECOVACS app is updated to latest version. 2. Cloud-side fixes are automatically applied when devices connect. 3. No device firmware update required for this specific cloud service vulnerability.
🔧 Temporary Workarounds
Disable cloud connectivity
allPrevent device from connecting to ECOVACS cloud services to eliminate remote exploitation vector
Disable in ECOVACS app settings or block device internet access at router
Disable camera/PIN features
allTurn off camera functionality or remove PIN protection if not essential
Configure in ECOVACS app under device settings
🧯 If You Can't Patch
- Segment IoT devices on separate network VLAN without internet access
- Implement strong authentication for ECOVACS accounts with MFA if supported
🔍 How to Verify
Check if Vulnerable:
Test if PIN bypass is possible by attempting to access live video feed without entering PIN while authenticatedCheck Version:
Check ECOVACS app version in app store/device settingsVerify Fix Applied:
Verify PIN prompt appears and blocks video access when PIN is not entered correctly📡 Detection & Monitoring
Log Indicators:
- Multiple failed PIN attempts followed by successful video access
- Video access logs without corresponding PIN validation
Network Indicators:
- Unusual video streaming patterns to unexpected IP addresses
- Cloud API calls bypassing PIN validation endpoints
