NVD · unedited
An undocumented (hidden) capability for switching the web interface in Hanwha Techwin Smartcams

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

Hanwha Techwin Smartcams contain an undocumented (hidden) capability that allows switching the web interface. This hidden functionality could be exploited by an attacker to manipulate or replace the camera's web interface, potentially enabling credential theft, authentication bypass, or injection of malicious content. The medium severity suggests network-based exploitation without authentication is possible.

MitigationApply vendor firmware updates when available, or isolate affected cameras on restricted network segments with firewall rules limiting access to trusted IP addresses only. Monitor for unauthorized interface changes.

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. Identify the device model
    Access the camera's web interface or use network enumeration to confirm the exact model number. Look for 'Snh V6410pn' or 'Snh V6410pnw' in the device information or DHCP fingerprints.
    Affected if The model is Hanwha Security Snh V6410pn or Snh V6410pnw (all firmware versions)
  2. Confirm firmware version
    Log into the camera's web interface and navigate to the system information or firmware version page. Alternatively, use the ONVIF or RTSP protocol to query device metadata.
    Affected if Any firmware version is installed on an affected model (all versions are vulnerable)
  3. Check for hidden interface switch capability
    Send an HTTP GET request to common hidden endpoints such as /cgi-bin/zm or /webui with modified parameters. Look for unexpected responses indicating an alternative web interface exists. Compare responses to the standard interface.
    Affected if The device responds to hidden or undocumented interface switch requests, indicating the undocumented capability is present
  4. Review web interface for unauthorized modifications
    Compare the current web interface appearance, available pages, and configuration options against a known-clean baseline or documentation. Check for unfamiliar pages, changed logos, or additional input fields.
    Affected if The web interface contains unfamiliar pages, modified elements, or configurations not present in the standard firmware
  5. Inspect network traffic for suspicious requests
    Use packet capture (tcpdump or Wireshark) on the camera's network segment. Look for HTTP requests to the camera with unusual parameters, especially those targeting /cgi-bin/ or similar paths that may trigger the hidden interface switch.
    Affected if Network traffic shows requests to undocumented endpoints or patterns indicative of interface manipulation attempts

You are affected if you have a Hanwha Security Snh V6410pn or Snh V6410pnw camera running any firmware version, as the undocumented hidden web interface switch capability is present in all versions.
