CVE-2020-26508
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 · uneditedThe WebTools component on Canon Oce ColorWave 3500 5.1.1.0 devices allows attackers to retrieve stored SMB credentials via the export feature, even though these are intentionally inaccessible in the UI.
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 confidenceThe WebTools component in Canon Oce ColorWave 3500 firmware 5.1.1.0 contains an information disclosure vulnerability where the export feature allows unauthenticated attackers to retrieve stored SMB credentials that are intentionally hidden from the device's normal UI.

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 modelAccess the device's web interface or check the device management console to confirm the model is Canon Oce ColorWave 3500Affected if Device model is Canon Oce ColorWave 3500
-
Check firmware versionNavigate to the device's system information or firmware settings page in the web interface, or query the WebTools component version endpoint, to verify the installed firmware versionAffected if Firmware version is exactly 5.1.1.0
-
Verify WebTools accessibilityAttempt to access the WebTools web interface by navigating to the device's IP address in a web browser, typically on port 80 or 443Affected if WebTools interface is accessible (no authentication required for the export feature)
-
Check for stored SMB credentialsUse the export functionality in WebTools (if accessible) to check whether stored SMB credentials can be retrieved, or review the device configuration for any SMB share configurations that are hidden from the normal UIAffected if SMB credentials are configured and stored on the device, and can be exported without authentication
A user is affected if they have a Canon Oce ColorWave 3500 running firmware version 5.1.1.0 with WebTools accessible and SMB credentials stored on the device.

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 dataApply vendor firmware patch if available; otherwise, implement network segmentation to isolate the device and restrict access to WebTools via firewall rules, or disable SMB sharing features if not required.
