CVE-2024-52548

6.7 MEDIUM

📋 TL;DR

This vulnerability allows attackers with command execution capabilities to bypass kernel code signing protections and execute arbitrary native code on affected Lorex security cameras. It affects Lorex 2K Indoor Wi-Fi Security Cameras running vulnerable firmware. Attackers could gain full control of the device.

💻 Affected Systems

Products:
  • Lorex 2K Indoor Wi-Fi Security Camera
Versions: All versions before firmware 2.800.0000000.8.R.20241111
Operating Systems: Embedded Linux-based firmware
Default Config Vulnerable: ⚠️ Yes
Notes: Requires initial command execution capability through other vulnerabilities or physical access. The Rapid7 blog mentions multiple vulnerabilities in these cameras that could provide initial access.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete device compromise allowing persistent backdoor installation, credential theft, lateral movement to other network devices, and use in botnets or surveillance operations.

🟠

Likely Case

Local privilege escalation from limited command execution to full root access, enabling installation of malware, data exfiltration, or disabling security features.

🟢

If Mitigated

Limited impact if devices are isolated in separate VLANs with strict network segmentation and no command execution vulnerabilities exist.

🌐 Internet-Facing: HIGH if cameras are directly exposed to the internet, as attackers could chain this with other vulnerabilities for remote exploitation.
🏢 Internal Only: MEDIUM if cameras are on internal networks only, requiring initial access through other means like phishing or compromised credentials.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploit requires initial command execution capability. The GitHub repository contains proof-of-concept code demonstrating the bypass. This would typically be chained with other vulnerabilities for complete exploitation.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.800.0000000.8.R.20241111

Vendor Advisory: Not explicitly provided in references, but firmware update is mentioned in Rapid7 blog

Restart Required: Yes

Instructions:

1. Log into camera management interface. 2. Navigate to firmware update section. 3. Download firmware version 2.800.0000000.8.R.20241111 from official Lorex sources. 4. Apply the update. 5. Reboot the camera. 6. Verify successful update.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate cameras in separate VLAN with strict firewall rules preventing outbound internet access and limiting inbound connections.

Disable Unnecessary Services

all

Turn off any unnecessary network services or features on the cameras to reduce attack surface.

🧯 If You Can't Patch

  • Segment cameras on isolated network with no internet access and strict firewall rules
  • Implement network monitoring for unusual outbound connections or command execution attempts

🔍 How to Verify

Check if Vulnerable:

Check firmware version via camera web interface or SSH if enabled. Compare against vulnerable versions.

Check Version:

Check via web interface at http://[camera-ip]/ or SSH command if available: cat /etc/version

Verify Fix Applied:

Confirm firmware version is 2.800.0000000.8.R.20241111 or later via camera management interface.

📡 Detection & Monitoring

Log Indicators:

  • Unusual process execution, kernel module loading attempts, privilege escalation attempts in system logs

Network Indicators:

  • Unexpected outbound connections from cameras, unusual command and control traffic patterns

SIEM Query:

source="camera_logs" AND (event="kernel_module_load" OR event="privilege_escalation" OR process="unusual_binary")
