Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in Vivotek CC8160 VVTK-0100d and classified as critical. Affected by this issue is the function read of the component httpd. The manipulation of the argument Content-Length leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-273524. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed that the affected release tree is end-of-life.

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

A stack-based buffer overflow vulnerability exists in the Vivotek CC8160 VVTK-0100d camera's httpd service. The vulnerability is in the 'read' function where manipulation of the HTTP Content-Length header allows overflowing a stack-based buffer, potentially enabling remote code execution.

MitigationThis product is end-of-life and unsupported with no vendor patch available; affected devices should be replaced with supported hardware. If immediate replacement is not feasible, network segmentation and restricting HTTP service access can reduce exposure.

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 check the device label/metadata to confirm the model is Vivotek CC8160
    Affected if Device model is Vivotek CC8160
  2. Check the firmware version
    Navigate to the camera's web interface (usually under System > Information or similar) or use the camera's API to retrieve the firmware version
    Affected if Firmware version is any version of Vivotek CC8160 (all versions are affected)
  3. Verify the httpd service is enabled
    Confirm the camera's HTTP web service is running by accessing the camera's IP address on port 80 or 443
    Affected if The HTTP service is accessible and running on the camera
  4. Assess network exposure
    Check if the camera's HTTP port is exposed to untrusted networks by reviewing firewall rules, NAT configurations, or network segmentation settings
    Affected if The camera's HTTP service is directly accessible from the internet or untrusted networks

If you have a Vivotek CC8160 camera with its HTTP service enabled and accessible, your environment is affected by this vulnerability.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

This product is end-of-life and unsupported with no vendor patch available; affected devices should be replaced with supported hardware. If immediate replacement is not feasible, network segmentation and restricting HTTP service access can reduce exposure.

Recommended fix High confidence
  1. This vulnerability affects Vivotek CC8160 which is end-of-life and unsupported by the vendor.
  2. No firmware update, patch, or mitigation is available for this vulnerability.
  3. Consider migrating to a currently supported Vivotek camera model if available.
  4. If migration is not possible, implement network segmentation to limit exposure of the affected device.
  5. Monitor the device for suspicious HTTP requests, particularly those with abnormally large Content-Length headers.
Caveat Product is end-of-life with no available updates; replacement with a supported device is the only remediation option
