NVD · unedited
Lorex 2K Indoor Wi-Fi Security Camera Device Management Server Improper Certificate Validation Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Lorex 2K Indoor Wi-Fi Security Cameras. User interaction is not required to exploit this vulnerability. The specific flaw exists within the device management functionality. The issue results from the lack of proper validation of the certificate presented by the server. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-26851.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This improper certificate validation vulnerability exists in the device management functionality of Lorex 2K Indoor Wi-Fi Security Cameras. The flaw allows network-adjacent attackers to exploit the lack of proper validation of server certificates, potentially enabling man-in-the-middle attacks to execute arbitrary code as root without any user interaction.

MitigationApply vendor-supplied firmware updates when available; until then, isolate devices on segmented networks and avoid untrusted networks to reduce exposure to man-in-the-middle attacks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm device model
    Identify the exact model number of your Lorex camera - check the device label, packaging, or the Lorex app/device settings for the model name. Verify it is a '2K Indoor Wi-Fi Security Camera' from Lorex.
    Affected if The device is NOT a Lorex 2K Indoor Wi-Fi Security Camera (different models are not affected by this specific CVE)
  2. Locate firmware version
    Access the camera through the Lorex app or web interface and navigate to Settings > Device Info > Firmware Version. Record the exact firmware build number shown.
    Affected if The firmware version matches or predates the version identified as vulnerable in Lorex's official security advisory (compare your version to vendor announcements)
  3. Verify device management feature is enabled
    Check the camera settings for remote device management, cloud connectivity, or remote access features. Look for options like 'Remote Viewing,' 'Cloud Backup,' or any feature that allows managing the camera over the network.
    Affected if Device management functionality is active and the camera communicates with external Lorex servers for updates, cloud storage, or remote access
  4. Assess network accessibility
    Determine if the camera is accessible from untrusted networks. Check your router firewall settings, port forwarding rules, and whether the camera is on a network shared with untrusted devices. Network-adjacent attackers must be able to reach the device.
    Affected if The camera is on a network where untrusted or unauthorized devices can communicate with it directly
  5. Inspect certificate validation behavior
    Use network capture tools (like Wireshark) on the camera's network traffic to observe how the device validates server certificates during device management communications. Look for connections to Lorex servers that succeed despite certificate errors or that use unencrypted protocols.
    Affected if The camera accepts connections to management servers without proper TLS certificate validation, or uses protocols that do not validate server certificates

You are affected if you own a Lorex 2K Indoor Wi-Fi Security Camera, the device management feature is enabled, and your firmware version predates the vendor's patched version - combined with network exposure that allows adjacent attackers to perform MITM attacks.
