CVE-2013-4613
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 default configuration of the administrative interface on the Canon MG3100, MG5300, MG6100, MP495, MX340, MX870, MX890, MX920, and MX922 printers does not require authentication, which allows remote attackers to modify the configuration by visiting the Advanced page. NOTE: the vendor has apparently responded by stating "for user convenience, the default setting does not require a password. However, if a user has a particular concern about third parties accessing the user's home printer, the default setting can be changed to add a password."
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 confidenceAffected Canon printer models (MG3100, MG5300, MG6100, MP495, MX340, MX870, MX890, MX920, MX922) ship with default configurations where the web-based administrative interface does not require authentication. Remote attackers can access the 'Advanced' settings page without credentials and modify printer configuration, potentially exposing sensitive network information or enabling further attacks.

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 printer modelAccess the printer's web interface by entering its IP address in a browser, or check the printer label/console for the model number (e.g., MG3100, MG5300, MG6100, MP340, MP495, MX870, MX890, MX920)Affected if The printer model matches one of the affected models: MG3100, MG5300, MG6100, MP340, MP495, MX870, MX890, or MX920 with all versions affected
-
Verify web interface is accessibleNavigate to the printer's IP address using HTTP (port 80) or HTTPS (port 443) in a web browser to confirm the Canon printer web console is reachableAffected if The web interface loads and responds, indicating the HTTP service is active on the printer
-
Test for unauthenticated access to Advanced settingsAttempt to access the 'Advanced' or 'Settings' page directly via the web interface without entering any username or passwordAffected if The Advanced settings page loads and allows configuration changes without prompting for credentials
-
Check network exposureReview the printer's network configuration to determine if it is directly accessible from untrusted networks (e.g., not behind a firewall, on a guest network, or directly exposed to the internet)Affected if The printer is reachable from untrusted networks without network-level filtering
The environment is affected if the printer model is one of the listed Canon models and the web administrative interface allows access to Advanced settings without requiring authentication, especially if the printer is accessible from untrusted networks.

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 dataEnable password protection on the printer's administrative interface via the web console, and ensure printers are not directly exposed to the internet or untrusted networks.
