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
OS command injection vulnerability in multiple digital video recorders provided by TAKENAKA ENGINEERING CO., LTD. allows a remote authenticated attacker to execute an arbitrary OS command on the device or alter the device settings.

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

OS command injection vulnerability in TAKENAKA ENGINEERING digital video recorders allows authenticated remote attackers to inject and execute arbitrary operating system commands through insecure input handling, potentially gaining full device control or modifying device configurations.

MitigationApply vendor firmware updates when available; if no patch exists, immediately restrict network access to DVRs, implement network segmentation, enforce strong authentication, and consider compensating controls such as WAF rules or IDS monitoring for suspicious command patterns.

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 TAKENAKA ENGINEERING DVR model
    Access the device web interface or check the device label/documentation for the exact model number and firmware version. Look for 'Takenaka Engineering' or 'TE-' branding on the device or in the admin interface.
    Affected if The device is a TAKENAKA ENGINEERING digital video recorder and the firmware version falls within any unpatched version range
  2. Check firmware version
    Log into the DVR admin panel (typically via HTTP/HTTPS on ports 80, 443, or 8080) and navigate to System > Information or Help > About to view the installed firmware version. If CLI access is available, run 'version' or 'show system info' commands.
    Affected if The installed firmware version is unknown, older than current available updates, or cannot be verified against patched versions
  3. Verify web interface exposure
    Scan network for open HTTP/HTTPS ports on the DVR (commonly ports 80, 443, 8080, 8443). Check router/firewall configurations to determine if the DVR web interface is accessible from external networks or the internet.
    Affected if The DVR web management interface is exposed directly to untrusted networks or the internet without VPN or firewall restrictions
  4. Inspect authentication configuration
    In the DVR admin panel, navigate to Security > Users or System > User Management. Verify that default credentials have been changed, strong passwords are enforced, and account lockout policies are enabled.
    Affected if Default administrative credentials are still in use, weak passwords are allowed, or authentication can be bypassed
  5. Check for suspicious processes or configurations
    If CLI or SSH access is available, run commands like 'ps', 'top', or 'netstat' to look for unexpected processes or network connections. Review system logs (/var/log/messages, /var/log/syslog) for command injection patterns, unusual API calls, or unauthorized command executions.
    Affected if Unexpected processes are running, unknown network connections exist, or logs contain evidence of injected/shell commands (e.g., semicolons, pipes, backticks in log entries)

A TAKENAKA ENGINEERING DVR with an unpatched or unknown firmware version, exposed web interface, and accessible authentication is likely vulnerable to command injection if the input handling feature is enabled.

Mitigation

Apply vendor firmware updates when available; if no patch exists, immediately restrict network access to DVRs, implement network segmentation, enforce strong authentication, and consider compensating controls such as WAF rules or IDS monitoring for suspicious command patterns.
