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
There is a command injection vulnerability in some Hikvision NVRs. This could allow an authenticated user with administrative rights to execute arbitrary commands.

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 is a command injection vulnerability (CWE-78) in Hikvision Network Video Recorders (NVRs). An authenticated user with administrative privileges can inject and execute arbitrary operating system commands due to insufficient input validation, potentially leading to complete device compromise.

MitigationApply available vendor firmware patches, restrict administrative access to trusted IPs only, and implement network segmentation to isolate NVR devices from untrusted networks.

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 Hikvision NVR device
    Access the device web interface or check network scan results for Hikvision NVR login page (typically port 80/443). Look for 'Hikvision' or 'NVR' in the web interface title or favicon.
    Affected if The device is a Hikvision Network Video Recorder with web management interface exposed.
  2. Confirm web management is network-accessible
    Check if ports 80, 443, or 8080 are open and responding on the NVR device from your detection position. Use 'nmap -p 80,443 <device-ip>' or similar network scan.
    Affected if The NVR web management interface is accessible from network segments that contain untrusted users.
  3. Verify administrative user exists
    Log into the NVR web interface with administrative credentials, or check user configuration to confirm at least one admin-level account is configured.
    Affected if An authenticated user with administrative privileges can access the NVR.
  4. Check firmware version
    In the NVR web interface, navigate to System > Maintenance > System Info or similar path to view the firmware version. Compare against any Hikvision security advisories for CVE-2024-29949.
    Affected if The installed firmware version matches the affected version range for this vulnerability (if published by vendor).

A user is affected if they have a Hikvision NVR with web interface exposed to network and an admin-authenticated user can access the command injection point.
