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 · unedited
Canon IJ Network Tool/Ver.4.7.5 and earlier (supported OS: OS X 10.9.5-macOS 13),IJ Network Tool/Ver.4.7.3 and earlier (supported OS: OS X 10.7.5-OS X 10.8) allows an attacker to acquire sensitive information on the Wi-Fi connection setup of the printer from the software.

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 confidence

This is an information disclosure vulnerability in Canon IJ Network Tool versions 4.7.5 and earlier (for macOS 10.9.5-macOS 13) and version 4.7.3 and earlier (for OS X 10.7.5-10.8). The software improperly exposes sensitive Wi-Fi connection setup details of the printer, which could be intercepted by an unauthenticated attacker on the network.

MitigationUpdate Canon IJ Network Tool to a version beyond 4.7.5 (or 4.7.3 for older OS X versions). If patching is not immediately possible, restrict network access to systems running this software and ensure printers are on a segregated network segment.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if Canon IJ Network Tool is installed
    On macOS, open Finder > Applications folder and look for 'Canon IJ Network Tool', or run: ls /Applications | grep -i 'Canon IJ Network'
    Affected if The application exists in the Applications folder
  2. Determine the installed version
    Right-click the application > Get Info > Version, or run: defaults read /Applications/Canon\ IJ\ Network\ Tool.app/Contents/Info CFBundleShortVersionString
    Affected if Version displays as 4.7.5 or lower for macOS 10.9.5+, or 4.7.3 or lower for OS X 10.7.5-10.8
  3. Confirm the OS version to determine the applicable affected range
    Run: sw_vers -productVersion
    Affected if Running macOS 10.9.5 through 13 (Ventura) with Canon IJ Network Tool version 4.7.5 or lower, OR OS X 10.7.5-10.8 with version 4.7.3 or lower
  4. Verify the application is network-accessible
    Check if the Canon IJ Network Tool service is running or bound to a network interface. On macOS, run: ps aux | grep -i 'Canon IJ' to see if the process is active
    Affected if The Canon IJ Network Tool process is actively running and accessible on the network

A user is affected if Canon IJ Network Tool version 4.7.5 or earlier (for macOS 10.9.5+) or 4.7.3 or earlier (for OS X 10.7.5-10.8) is installed and the software is network-accessible, allowing unauthenticated attackers to intercept Wi-Fi setup details.

Upgrade available Upgrade to a release after 4.7.5
Interim mitigation

Update Canon IJ Network Tool to a version beyond 4.7.5 (or 4.7.3 for older OS X versions). If patching is not immediately possible, restrict network access to systems running this software and ensure printers are on a segregated network segment.

Recommended fix Moderate confidence

Canon IJ Network Tool version 4.7.6 or later for the applicable macOS range
