The first and original vulnerability was identified as. Learn how to find this issue in the wild by using Google dorks, determine the factors that indicate a DotNetNuke web app is vulnerable, go through hands-on examples, and much more! You can start by analyzing the vulnerable source code of how the application processes the DNNPersonalization cookie XML value. How can I exploit DNN cookie deserialization? If you don’t want to update and prefer to stick with the current version, you have to change the page the users will be redirected to once they trigger a 404 error (the homepage is a usual recommendation). through the VERIFICATION_PLAIN variable, which you can extract by inspecting the source code of the “Edit Profile” page within any user settings page. 6.1: 2019-09-26: CVE-2019-12562: Stored Cross-Site Scripting in DotNetNuke (DNN) Version before 9.4.0 allows remote attackers to store and embed the malicious script into the admin notification page. Regardless of the official CVE details, this issue affects only the 9.1.1 DNN version. The encryption key also presented a poor randomness level (low-entropy). This process will take a little longer, depending on the number of encrypted registration codes you have collected. The exploitation is straightforward by passing the malicious payload through the DNNPersonalization cookie within a 404 error page. We also display any CVSS information provided within the CVE List from the CNA. If the message “The target appears to be vulnerable” is returned after you run the check, you can proceed by entering the “exploit” command within Metasploit Console. The Exploit Database is a non-profit project that is provided as a public service by Offensive Security. The application will parse the XML input, deserialize, and execute it.

The patch for CVE-2018-15811 added the session cookie as a participant in the encryption scheme. But this should not be a big issue if the encryption algorithm would be changed to a stronger and current one. to CVE-2017-9822. This cryptography scheme was used to encrypt both the DNNPersonalization cookie and the registration code sent to the email when you sign up through a DotNetNuke application that uses Verified Registration. If you get the “The target appears to be vulnerable” message after running the check, you can proceed by entering the “exploit” command within Metasploit Console. 14 Feb 2020 — DNN asked for technical details again!! DotNetNuke is a free and open-source web CMS (content management system) written in C# and based on the .NET framework.

This process could overwrite files that the user was not granted permissions to, and would be … Also, DNN supports verified registration of new users through email, but you need to configure a valid SMTP server in order for this security feature to be working. You have to get the unencrypted format of this code by logging in as the new user, navigating to the “Edit Profile” page, inspecting the source code, and searching for the values of “userID” and “portalID” (possible to return a negative value. You can install DNN on a stack that includes a Windows Server, IIS, ASP.NET, and SQL Server for Windows. Before we start, keep in mind the vulnerability was released under CVE-2017-9822, but the development team consistently failed at patching it, so they issued another four bypasses: We’ll look at all of them in the steps below.
