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 · uneditedUse of a non-secure protocol as the default FTP configuration in Canon EOS Network Setting Tool Version 1.5.0 or earlier
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 · moderate confidenceThe Canon EOS Network Setting Tool version 1.5.0 and earlier defaults to unencrypted FTP protocol for network file transfers, exposing authentication credentials and transmission data to interception over the network.

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.
-
Verify Canon EOS Network Setting Tool is installedCheck for the application in standard program installation directories or use system utilities to list installed software. Look for 'Canon EOS Network Setting Tool' or 'NETWORK' in the program name.Affected if The application is present on the system
-
Determine installed version numberRight-click the application executable or access the program's About/Help section to view the version. Compare the version against the affected range of 1.5.0 and earlier.Affected if The installed version is 1.5.0 or earlier (version number less than 1.5.1)
-
Inspect network transfer protocol configurationOpen the Canon EOS Network Setting Tool and navigate to network settings or transfer configuration options. Look for the protocol setting used for file transfers.Affected if The default or active protocol is set to plain/unencrypted FTP rather than SFTP or FTPS
Affected if Canon EOS Network Setting Tool version 1.5.0 or earlier is installed AND the application is configured to use unencrypted FTP as the default transfer protocol.
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.
