CVE-2024-52544
📋 TL;DR
An unauthenticated attacker can remotely execute arbitrary code on Lorex 2K Indoor Wi-Fi Security Cameras by exploiting a stack-based buffer overflow in the DP Service on TCP port 3500. This affects all systems running vulnerable firmware versions, allowing complete device compromise without authentication.

⚠️ Risk & Real-World Impact
Worst Case
Full remote code execution leading to complete device takeover, camera feed interception, lateral movement to other network devices, or use as a botnet node.
Likely Case
Remote code execution resulting in camera compromise, video feed access, and persistence on the device for further attacks.
If Mitigated
Attack blocked at network perimeter with no successful exploitation due to proper segmentation and access controls.
🎯 Exploit Status
Public exploit code exists in the LorexExploit repository, making exploitation straightforward for attackers.

🔧 Temporary Workarounds
Network Segmentation
linuxBlock access to TCP port 3500 from untrusted networks
iptables -A INPUT -p tcp --dport 3500 -j DROP
Access Control
windowsRestrict access to port 3500 using firewall rules
netsh advfirewall firewall add rule name="Block Lorex DP Service" dir=in action=block protocol=TCP localport=3500
🧯 If You Can't Patch
- Isolate cameras on a dedicated VLAN with no internet access
- Implement network-based intrusion prevention to detect and block exploit attempts
🔍 How to Verify
Check if Vulnerable:
Check if port 3500 is open and accessible: nmap -p 3500 <camera_ip>Check Version:
Check camera web interface under Settings > System > Firmware VersionVerify Fix Applied:
Verify firmware version matches 2.800.0000000.8.R.20241111 in web interface📡 Detection & Monitoring
Log Indicators:
