    Hi, we recently had someone create a folder and an aspx file in the root of dnn site via URL injection. This site is an old version "DNN 7.0"  that was due to be upgraded. 

    Another Dnn site ver 9.1.1  site had a unknown text file in the root which is obviously an attempt to test an attack. Has anyone experienced similar or  any knowledge of how this may have been done??

    is there something that can be done to secure the root folders/prevent url injection or test a site to see if secure?, will an upgrade sort the problem out.

    Any advice is appreciated at this point

        They are on GitHub organized like this: https://github.com/dnnsof....Releases.Archive.6x

        Change the 6 to the series that you want.

            Stuart,

            please also consider that the hack could come from another source - e.g. weak FTP setup/password.

            Happy DNNing!
            Michael

              Cheers guys.
              Hi Michael, defo worth looking closer at Firewall logs, even though we have never allowed FTP and none other than ICT staff connect to the server using RDP
