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
** DISPUTED ** A vulnerability, which was classified as problematic, was found in Intelbras MHDX 1004, MHDX 1008, MHDX 1016, MHDX 5016, HDCVI 1008 and HDCVI 1016 up to 20240401. This affects an unknown part of the file /cap.js of the component HTTP GET Request Handler. The manipulation leads to information disclosure. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The identifier VDB-258933 was assigned to this vulnerability. NOTE: The vendor explains that they do not classify the information shown as sensitive and therefore there is no vulnerability which is about to harm the user.

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

An information disclosure vulnerability exists in Intelbras MHDX and HDCVI surveillance DVR devices where the /cap.js endpoint in the HTTP GET request handler returns information that could be accessed remotely without authentication.

MitigationSince the vendor disputes this as a vulnerability and no patch is available, implement network segmentation and firewall rules to restrict external access to the device's web interface, or contact Intelbras for clarification and official guidance.

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 is Intelbras MHDX or HDCVI DVR
    Access the device web interface or check physical device labeling, or query the device's HTTP response headers for Intelbras product identification strings
    Affected if The device is an Intelbras MHDX or HDCVI surveillance DVR model
  2. Verify HTTP web interface is exposed
    Attempt to access the device IP address on common HTTP ports (80, 8080, 443) using a web browser or curl command
    Affected if The device web interface responds to HTTP requests and is reachable on the network
  3. Test /cap.js endpoint for unauthenticated access
    Send a GET request to http://[device-ip]/cap.js without providing any authentication credentials
    Affected if The /cap.js endpoint returns an HTTP 200 response without requiring login credentials
  4. Inspect response for sensitive information
    Examine the content returned by /cap.js for potentially sensitive data such as system configuration, file paths, version details, or internal network information
    Affected if The /cap.js response contains information that should not be publicly accessible (configuration details, paths, version numbers, or other internal data)

A user is affected if they have an Intelbras MHDX or HDCVI DVR device whose web interface is accessible and the /cap.js endpoint returns sensitive information without requiring authentication.

Mitigation

Since the vendor disputes this as a vulnerability and no patch is available, implement network segmentation and firewall rules to restrict external access to the device's web interface, or contact Intelbras for clarification and official guidance.
