CVE-2019-20461
📋 TL;DR
This vulnerability allows unauthenticated attackers to access Alecto IVM-100 camera feeds over the internet by exploiting a custom UDP protocol that lacks server-side authentication. Only the encoded UID is required to establish sessions, enabling unauthorized video/audio streaming. All users of affected Alecto IVM-100 devices are impacted.

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of camera feeds allowing unauthorized surveillance, potential privacy violations, and integration into botnets for DDoS attacks.
Likely Case
Unauthorized access to live camera feeds enabling surveillance of private spaces and potential blackmail/extortion opportunities.
If Mitigated
Limited to internal network access only, preventing internet-based attacks but still vulnerable to local network threats.
🎯 Exploit Status
Protocol has been reverse engineered and documented. Exploitation requires only the encoded UID which may be obtained through network scanning or other means.

Restart Required: No
Instructions:
No official patch exists. Contact vendor for potential firmware updates or replacement options.
🔧 Temporary Workarounds
Network Segmentation
linuxIsolate IVM-100 devices from internet access using firewall rules
iptables -A FORWARD -p udp --dport [IVM_PORT] -j DROP
iptables -A INPUT -p udp --dport [IVM_PORT] -j DROP
VLAN Isolation
allPlace cameras on separate VLAN without internet routing
🧯 If You Can't Patch
- Disable internet-facing access completely using firewall rules
- Replace affected devices with models using secure authentication protocols
🔍 How to Verify
Check if Vulnerable:
Check if device responds to UDP packets on the custom protocol port without authentication. Use network scanner to identify IVM-100 devices on network.Check Version:
Check device firmware version via web interface or serial console if availableVerify Fix Applied:
Verify devices are not accessible from internet. Test UDP protocol access from external networks.📡 Detection & Monitoring
Log Indicators:
- Unexpected UDP connections to camera ports
- Multiple failed authentication attempts (if logging exists)
Network Indicators:
- UDP traffic to IVM-100 devices from external IPs
- Pattern of UDP packets matching reverse-engineered protocol
