DNN (DotNetNuke) < 7.4.1 Administration Authentication Bypass Vulnerability

critical Nessus Plugin ID 100934

Language:

Synopsis

An application running on the remote web server is affected by an authentication bypass vulnerability.

Description

The version of DNN (formerly DotNetNuke) running on the remote web server is prior to 7.4.1. It is, therefore, affected by an authentication bypass vulnerability due to a failure to delete installation wizard scripts post-installation. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to create new administrator accounts and bypass authentication.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to DNN version 7.4.1 or later. Alternatively, as a workaround, delete the InstallWizard.aspx and InstallWizard.aspx.cs files.
