DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. A url could be crafted to the DNN ImageHandler to render text from a querystring parameter. This text would display in the resulting image and a user that trusts the domain might think that the information is legitimate. This vulnerability is fixed in 9.13.4.
