Check out this report from the Australian Cyber Security Centre regarding an exploit concerning DNN and FCK editor.

Some interesting reading on how an exploit was performed, what they did and how to avoid it.

Rod,

there is no word about which version of DNN is (or hopefully was) in use. But FCK Editor has not been supported on DNN since - I don't know, but my guess is DNN 5. (Telerik) RadEditor was in use then, and since DNN 7 it is CK Editor. I therefore suspect that the issue is that the investigated site has not been updated for years.

This is a risk, we all should know. But: Just updating is not enough. Many extensions (modules, skins,...) may (or will) break, esp. when you upgrade - even in steps - from DNN 4 to 9, even from 7 to 9. Therefore it is better to invest in a hosting company that will check everything and make the necessary updates of the modules and other extensions as well. Even if this could be a bit more expensive.

And: There is more to security than the security advisor, upgrades and activating https. Have you ever checked your site with https://securityheaders.io, https://www.ssllabs.com/ssltest/ or similar tools? Have you implemented a content security policy (CSP)? Have you secured the database access, or is the user running the site in the databases's db_owner or SQL Server's Sysadmins role? etc. etc.

Happy DNNing!
Michael
