CVE-2025-6562
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 · uneditedCertain hybrid DVR models (HBF-09KD and HBF-16NK) from Hunt Electronic have an OS Command Injection vulnerability, allowing remote attackers with regular privileges to inject arbitrary OS commands and execute them on the device.
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 confidenceHunt Electronic hybrid DVR models HBF-09KD and HBF-16NK contain an OS Command Injection vulnerability in their web interface or API. Attackers with regular (non-administrator) user credentials can submit specially crafted input that gets executed by the underlying operating system, potentially allowing complete device compromise.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify device modelCheck the physical device label or log into the web interface and navigate to System Information or Device Info page to confirm the model is HBF-09KD or HBF-16NKAffected if The device model is either HBF-09KD or HBF-16NK from Hunt Electronic
-
Determine firmware versionIn the DVR web interface, go to System Settings or About page and record the firmware version. Alternatively, access the device via SSH or serial console and run 'version' or check '/proc/version' if availableAffected if The firmware version matches or falls within the affected version range for these models (compare your version to any official vendor advisory)
-
Verify web interface is enabledAttempt to access the DVR web interface via HTTP/HTTPS on the device IP address. Check in System Settings whether the web service or remote management feature is turned onAffected if The web interface or API is accessible and enabled on the device
-
Check for non-administrator accountsLog into the DVR as an administrator and navigate to User Management or Account Settings. Review the list of configured users and note their privilege levelsAffected if There is at least one user account with non-administrator or limited privileges configured on the device
-
Assess network exposureFrom a trusted internal host, verify the DVR web port is reachable. Check if the device is on an isolated VLAN or directly accessible from untrusted networksAffected if The DVR web interface is accessible from network segments that contain untrusted users or systems
A user is affected if they have a Hunt Electronic HBF-09KD or HBF-16NK DVR with the web interface enabled and at least one non-administrator user account configured, especially if the device is accessible from less-trusted network segments.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataIf vendor firmware updates are unavailable, implement network segmentation to isolate DVR devices and consider deploying a web application firewall to filter malicious input. Regularly audit user accounts and privilege levels.
