CVE-2022-4621
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 · uneditedPanasonic Sanyo CCTV Network Cameras versions 1.02-05 and 2.03-0x are vulnerable to CSRFs that can be exploited to allow an attacker to perform changes with administrator level privileges.
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 confidencePanasonic Sanyo CCTV Network Cameras versions 1.02-05 and 2.03-0x contain a CSRF vulnerability in their web interface. Attackers can craft malicious links or pages that, when visited by an authenticated administrator, cause the browser to send unintended requests to the camera, allowing the attacker to make configuration changes with administrator-level privileges.

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 camera model and firmware versionAccess the camera web interface and navigate to the system information or firmware version page, typically under Settings, System, or About sectionsAffected if The displayed firmware version matches any affected version: 2.03-06 (Vcc Hd5600p), 1.02-05 or 2.03-08 (Vcc Hd3300p), 2.03-02 (Vcc Hd3300, Vcc Hd2100p), or 2.03-00 (Vcc Hd3100p)
-
Confirm web interface is enabledVerify the camera HTTP/HTTPS web interface is accessible on the network by attempting to reach the camera IP address in a browserAffected if The web interface is reachable and accepts authentication, which is required for the CSRF attack to execute against an authenticated administrator
-
Check for anti-CSRF token presenceInspect the HTML source of configuration pages in the web interface. Look for hidden input fields with random-looking values in forms that perform state-changing actionsAffected if Forms lack hidden anti-CSRF token fields, meaning requests can be forged from external pages
-
Verify Origin/Referer header validationSubmit a configuration change request from an external domain (or with modified headers) using a tool like curl to see if the camera rejects itAffected if The camera accepts configuration requests without validating that the request originated from its own web interface
You are affected if your Panasonic camera model and firmware version match the affected versions listed AND the web interface is accessible and lacks anti-CSRF protections.
Generated from the published advisory. Verify against your own configuration.
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 dataImplement anti-CSRF tokens in the camera firmware's web interface and validate Origin/Referer headers on state-changing requests. If firmware updates are unavailable from the vendor, deploy compensating controls such as network isolation, strict browser policies, and educate administrators about not clicking untrusted links while authenticated.
