CVE-2015-5631
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 · uneditedCross-site request forgery (CSRF) vulnerability in the Remote UI on Canon PIXMA MG7500 printers allows remote attackers to hijack the authentication of administrators.
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 confidenceCross-site request forgery (CSRF) vulnerability in the Remote UI of Canon PIXMA MG7500 printers allows remote attackers to trick authenticated administrators into unknowingly executing unintended actions (e.g., changing settings, configuring network parameters) by leveraging the trust the web application places in the administrator's authenticated session.

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 printer modelAccess the printer's web interface or check the device label/menu to confirm the exact model number (e.g., MG7550, MG7560, etc.)Affected if The printer model is any variant within the Canon PIXMA MG7500 series
-
Verify Remote UI is enabledCheck the printer's network settings or control panel menu for the Remote UI / Web UI feature. Attempt to access the web interface by entering the printer's IP address in a browserAffected if Remote UI is enabled and accessible via HTTP/HTTPS on the network
-
Inspect form submissions for CSRF protectionLog into the Remote UI as administrator, navigate to settings pages that perform actions (network settings, admin password, etc.), and examine HTML forms for the presence of anti-CSRF tokens or random session identifiersAffected if Forms lack anti-CSRF tokens (hidden fields with random values) and do not validate Origin or Referer headers
-
Test for CSRF vulnerabilityFrom an external host, craft a test HTML page with a form that targets the printer's Remote UI endpoint and submit it while authenticated (e.g., via a logged admin session)Affected if The action completes without requiring a unique token or proper header validation
If the device is a Canon PIXMA MG7500 series printer with Remote UI enabled and the web forms lack anti-CSRF tokens, the environment is affected by this vulnerability.

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 or proper Origin/Referer header validation in the Remote UI. In the interim, apply network segmentation to isolate printers from untrusted networks and advise administrators to avoid browsing untrusted sites while logged into the printer admin interface.
