“Site Settings” -> “Advanced Settings” and look for the “404 Error Page” dropdown menu. Finally, 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. According to them, over 750,000 organizations deployed web platforms powered by DotNetNuke worldwide. 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. This process will take a little longer, depending on the number of encrypted registration codes you have collected. As a content management system and web application framework, DNN can help you build nearly anything online, and can even integrate with mobile apps and any other system. DotNetNuke GetShell & execute exploit Exploit Title: DotNetNuke DNNspot Store <=3.0 GetShell exploit Date: 31/03/2015 Author: k8gege 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. After that, the other four CVEs were released based on the same issue, DotNetNuke Cookie Deserialization RCE, but they are only bypasses of the failed attempts at patching the first CVE. You can find those issues in the DotNetNuke from 9.2.2 to 9.3.0-RC. 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.  (DotNetNuke Cookie Deserialization in Pentagon’s HackerOne Bug Bounty program), (DotNetNuke Cookie Deserialization in Government website). 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. You don’t have to bypass any patching mechanism.

We looked at around 300 DotNetNuke deployments in the wild and discovered that one in five installations was vulnerable to CVE-2017-9822. You can use the following Google dorks to find available deployments across the Internet and test them against the DotNetNuke Cookie Deserialization CVE: Deserialization is the process of interpreting streams of bytes and transforming them into data that can be executed by an application. DotNetNuke uses the DNNPersonalization cookie to store anonymous users’ personalization options (the options for authenticated users are stored through their profile pages). (/DNN Platform/Library/Common/Utilities/XmlUtils.cs). An exploit could allow the attacker to cause unexpected behaviors such as high CPU usage, process crashes, or even full system reboots of an affected device. We looked at around 300 DotNetNuke deployments in the wild and discovered that one in five installations was vulnerable to CVE-2017-9822. Patches for these vulnerabilities are already available. The idea sounds good and effective, except if the DNNPersonalization key was derived from the registration code encryption key. Passionate about breaking stuff. Having both the encrypted and plaintext codes, you can launch a known-plaintext attack and encrypt your payload with the recovered key. Oh, wait… I forgot to mention the encryption remained the same (DES) and no changes were applied to it. Looking for a fix? Description: DotNetNuke – Cookie Deserialization Remote Code Execution (Metasploit) Published: Thu, 16 Apr 2020 00:00:00 +0000 Source: EXPLOIT-DB.COM The first patch consisted of a DES implementation, which is a vulnerable and weak encryption algorithm. 23 CVE-2008-6399: 264: 2009-03-05: 2009-03-06 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. The VERIFICATION_CODE value is the full path of the local file containing the codes you collected from the users you registered. method to open the calculator on the remote target. 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. CVE-2018-18326CVE-2018-18325CVE-2018-15812CVE-2018-15811CVE-2017-9822 . DotNetNuke Cookie Deserialization in Pentagon’s HackerOne Bug Bounty program, Scan your web application periodically with. This module exploits a deserialization vulnerability in DotNetNuke (DNN) versions 5.0.0 to 9.3.0-RC. 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). Privacy  /   Terms and Policy   /   Site map  /   Contact. But this should not be a big issue if the encryption algorithm would be changed to a stronger and current one. You can use the following Google dorks to find available deployments across the Internet and test them against the DotNetNuke Cookie Deserialization CVE: Deserialization is the process of interpreting streams of bytes and transforming them into data that can be executed by an application. To resolve the following Telerik Component vulnerabilities: CVE-2017-11317, CVE-2017-11357, CVE-2014-2217, you will need to apply a patch that has been developed by DNN from their Critical Security Update - September2017 blog post.Customers may also want to keep utilizing their Telerik module in DNN 9 without being forced to upgrade the whole instance.
