Security bulletins released

DNN Platform 7.4.1 has been released. The release notes can be found here

This release resolves the following four security issues -full details can be read at

  • 2015-02 (Low) ability to confirm file existence
  • 2015-03 (Low) Version information leakage
  • 2015-04 (Low) Server-Side Request Forgery in File Upload
  • 2015-05 (Critical) unauthorized users may create new host accounts

The first three are all "low" level issues, but the fourth one is categorized as "critical". Typically that would mean that you should upgrade to 7.4.1 as soon as possible, however there is an alternative solution for those who can't upgrade right away.

As an alternative to upgrading to 7.4.1 , delete the install/installwizard.aspx and install/installwizard.aspx.cs files and the issue is resolved.

Note: We recommend users install as it will automate the deletion of these files, as well as provide additional security functionality.
