Detection Guidance

This vulnerability involves the use of hard-coded cryptographic keys in Canon EOS Network Setting Tool Version 1.5.0 or earlier. Detection would primarily involve identifying the presence of the affected software versions on your system.

To detect if the vulnerable software is installed, you can check the version of the EOS Network Setting Tool or EOS Utility installed on your system.

• On Windows, you can check installed programs via Control Panel or use PowerShell commands such as: Get-ItemProperty 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*' | Select-Object DisplayName, DisplayVersion | Where-Object { $_.DisplayName -like '*EOS Utility*' }
• On macOS, you can check the version of EOS Utility by opening the application and selecting 'About EOS Utility' or by running: mdls -name kMDItemVersion /Applications/EOS\ Utility.app

If the installed version of EOS Utility is between 3.12.0 and 3.20.20 (which includes EOS Network Setting Tool Ver.1.5.0 or earlier), your system is potentially vulnerable.

No specific network detection commands or signatures are provided in the available resources for detecting exploitation attempts of this vulnerability.
