DNN (DotNetNuke) __dnnVariable Parameter XSS

medium Nessus Plugin ID 69400

Synopsis

The remote web server contains an ASP.NET application that is affected by a cross-site scripting vulnerability.

Description

The version of DNN installed on the remote host is affected by a cross-site scripting vulnerability due to a failure to properly sanitize user-supplied input to the ' __dnnVariable' parameter. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to inject arbitrary HTML and script code into a user's browser to be executed within the security context of the affected site.

Note that the application is reportedly also affected by an additional cross-site scripting issue as well as a redirect error that can lead to phishing attacks; however, Nessus has not tested for these additional issues.

Solution

Upgrade to DNN version 6.2.9 / 7.1.1 or later.
