    Hi,

    We have DNN version 08.05.00 installed for our website and with the Log4j vulnerability making everyone nervous, the security team in my company is looking for an official word on if DNN can be impacted by this. Looking at the details for the vulnerability I doubt that it can impact us but can someone from the team reply an confirm?

    Thanks,

    Sumit

      Inquiring minds want to know! IMO probably not, since there don't appear to be any java components in DNN. That said I wonder if IIS or other server components use this component for logging? Please correct me if I am wrong!

        My understanding is that an official statement is in the works, but that DNN Platform does not use Log4j in any way. It's a .NET application and Log4j requires Java, so even a 3rd party extensions cannot introduce Log4j into DNN (though 3rd party extensions could depend on an external service that is vulnerable).

          We are on version 6.02 of DNN and are in the process of upgrading. It seems that this version may use log4j. Can anyone verify that this is the case? If so, is there any mitigation around what should be done. Any help is appreciated. Have a great day!

            What Brian said above. This is valid for all DNN versions, it is based on ASP.Net, so it cannot use log4j. Anyway, if any custom or 3rd party module depends on an external service that uses log4j, this service could be vulnerable, but I have never seen such a thing (but there are things I have not seen yet...).

            If you are using a custom or 3rd party module you should ask the manufacturer/vendor. DNN itself is not affected by this exploit.

            Happy DNNing!
