CVE-2025-47822
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 · uneditedFlock Safety LPR (License Plate Reader) devices with firmware through 2.2 have an on-chip debug interface with improper access control.
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 confidenceFlock Safety License Plate Reader devices running firmware version 2.2 and earlier contain an on-chip debug interface (such as JTAG or SWD) that lacks proper access control restrictions. This allows an attacker with physical or local network access to potentially attach debuggers to the device, read firmware contents, or manipulate device behavior.

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 the device modelLocate the physical Flock Safety License Plate Reader device or check network inventory for devices with manufacturer identifier 'Flock Safety' and product type indicating License Plate Reader functionalityAffected if The device is a Flock Safety LPR unit
-
Check the firmware versionAccess the device administrative interface or check device configuration/status to retrieve the current firmware version numberAffected if The firmware version is 2.2 or lower, or the version cannot be determined (treated as potentially affected)
-
Determine if debug interfaces are network-accessibleScan the device IP address for open ports associated with debug interfaces such as JTAG (ports 20, 21, 80, 443 for debug services), SWD, or proprietary debug protocols. Check network firewall rules allowing access to these ports from untrusted networksAffected if Debug ports are open and reachable from local network segments without authentication requirements
-
Verify physical debug port accessibilityInspect the device hardware for exposed debug headers (20-pin JTAG, 10-pin SWD, or similar debug connectors) with unconstrained physical accessAffected if Debug headers are present and physically accessible without tamper evident protections
The environment is affected if Flock Safety LPR devices are running firmware version 2.2 or earlier AND the on-chip debug interface is accessible either physically or over the network without authentication.

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 dataDisable or properly authenticate the on-chip debug interface in firmware, and deploy an updated firmware version that remediates the access control issue to all affected LPR devices.
