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
Digiever DS-2105 Pro 3.1.0.71-11 devices allow time_tzsetup.cgi Command Injection. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

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 · high confidence

Command injection vulnerability in the time_tzsetup.cgi endpoint of Digiever DS-2105 Pro NVR devices (version 3.1.0.71-11) allows remote attackers to execute arbitrary operating system commands via unsanitized input. The CVSS 8.8 score reflects high exploitability and significant impact on confidentiality, integrity, and availability.

MitigationThis is an end-of-life product receiving no security updates; immediate network isolation or segmentation is required, followed by replacement with a supported device from a vendor providing regular security patches.

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 device model
    Access the NVR web interface or check device documentation to confirm the exact model is Digiever DS-2105 Pro or DS-2105 Pro+.
    Affected if Device is not a Digiever DS-2105 Pro or DS-2105 Pro+ model.
  2. Check firmware version
    Log into the NVR admin interface and navigate to System > System Information > Firmware Version, or access the device via SSH and run 'cat /etc/version' or 'version' command to determine the installed firmware version.
    Affected if Firmware version is exactly 3.1.0.71-11.
  3. Locate time_tzsetup.cgi script
    Access the web interface and navigate to the CGI endpoint path, typically at /cgi-bin/time_tzsetup.cgi, or check the device filesystem via SSH for the presence of this script in the /www/cgi-bin/ or /cgi-bin/ directory.
    Affected if The time_tzsetup.cgi script exists and is accessible on the device.
  4. Verify CGI interface accessibility
    Attempt to access http://[device-ip]/cgi-bin/time_tzsetup.cgi from a browser or use curl to send a request to the CGI endpoint to confirm it responds.
    Affected if The CGI script responds to HTTP requests, indicating it is enabled and accessible.
  5. Assess network exposure
    Check firewall rules, ACLs, or VLAN configuration to determine if the device web interface and CGI scripts are accessible from untrusted networks or the internet.
    Affected if The device web interface (port 80/443) is reachable from untrusted networks without proper access controls.

A user is affected if they have a Digiever DS-2105 Pro or DS-2105 Pro+ NVR running firmware version 3.1.0.71-11 with the time_tzsetup.cgi script accessible over the network.

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

This is an end-of-life product receiving no security updates; immediate network isolation or segmentation is required, followed by replacement with a supported device from a vendor providing regular security patches.

Recommended fix High confidence
  1. Replace the end-of-life Digiever DS-2105 Pro/Pro+ devices with currently supported surveillance hardware from Digiever or an alternative vendor
  2. If immediate replacement is not feasible, isolate affected devices on a restricted network segment with strict firewall rules limiting access to trusted management IPs only
  3. Disable any unnecessary network services and CGI interfaces on the affected devices if the web interface cannot be disabled
  4. Implement additional network monitoring and logging for the affected devices to detect potential exploitation attempts
  5. Consider deploying compensating controls such as intrusion detection/prevention systems (IDS/IPS) on network segments containing these devices
Caveat These devices are end-of-life and no longer receive security updates from the vendor; replacement is the only durable remediation
