DNN (aka DotNetNuke) 9.2 through 9.2.2 incorrectly converts encryption key source values, resulting in lower than expected entropy. (DotNetNuke Cookie Deserialization in Pentagon’s HackerOne Bug Bounty program), (DotNetNuke Cookie Deserialization in Government website). webapps exploit for Multiple platform Current Description . DotNetNuke Cookie Deserialization Remote Code Execution. Later edit [June 11, 2020]: As part of this research, we discovered a Remote Code Execution vulnerability exploitable through DNN Cookie Deserialization in one of the U.S. Department Of Defense’s biggest websites. Pandora FMS - Ping Authenticated Remote Code Execution (Metasploit) 2020-04-18 . Based on the extracted type, it creates a serializer using XmlSerializer. The VERIFICATION_PLAIN value is in the same format. According to the advisory, the CVE-2018-2628 is a high-risk vulnerability that scores 9.8 in the CVSS v3 system. This process will take a little longer, depending on the number of encrypted registration codes you have collected. Artworks Gallery 1.0 - Arbitrary File Upload RCE (Authenticated) via Edit Profile. DotNetNuke Cookie Deserialization RCE. Because the XML cookie value can be user-supplied through the request headers, you can control the type of the XmlSerializer. The resulting request will ultimately look like this. Reading Time: 10 minutes We looked at around 300 DotNetNuke deployments in the wild and discovered that one in five installations was vulnerable to CVE-2017-9822.That includes governmental and banking websites. According to them, over 750,000 organizations deployed web platforms powered by DotNetNuke worldwide. The associated CVSS 3.1 score is a 9.8 critical. We looked at around 300 DotNetNuke deployments in the wild and discovered that one in five installations was vulnerable to CVE-2017-9822. 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. You can find this vulnerability in DotNetNuke versions from 9.2.0 to 9.2.1. msf5 exploit(windows/http/dnn_cookie_deserialization_rce) > set SESSION_TOKEN <.DOTNETNUKE>, msf5 exploit(windows/http/dnn_cookie_deserialization_rce) > set TARGET 3. Just as soon as I get through all the Java stuff I was uneasy with they through .NET at you. they're used to gather information about the pages you visit … 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. And the class Example2 has a magic function that runs eval() on user-provided input. We could observe differences between Java and Python in deserialization This occurs when DNN is configured to handle 404 errors with its built-in error page (default configuration). 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. by Cristian Cornea June 10, 2020. by Cristian Cornea June 10, 2020. … The expected structure includes a "type" attribute to instruct the server which type of object to create on deserialization. Data which is untrusted cannot be trusted to be well formed. CWE-502: CWE-502: High : Invision Power Board version 3.3.4 unserialize PHP code execution: CVE-2012-5692.

This module exploits a deserialization vulnerability in DotNetNuke (DNN) versions 5.0.0 to 9.3.0-RC. 07/19/2016. Python's Pickle Remote Code Execution payload template. The exploitation is straightforward by passing the malicious payload through the DNNPersonalization cookie within a 404 error page. The first patch consisted of a DES implementation, which is a vulnerable and weak encryption algorithm. Affects DotNetNuke versions 5.0.0 to 9.1.0. Vulnerable versions store profile information for users in the DNNPersonalization cookie as XML. DotNetNuke uses the DNNPersonalization cookie to store anonymous users’ personalization options (the options for authenticated users are stored through their profile pages). Vulnerable versions store profile information for users in the DNNPersonalization cookie as XML. You have to expect the process to take some minutes, even hours.                                             <ExpandedElement/> In a new report by cybersecurity firm Sansec, Claire’s website was compromised by attackers who attempted to steal customer’s payment information when purchasing from the site. DotNetNuke Cookie Deserialization Remote Code Excecution This module exploits a deserialization vulnerability in DotNetNuke (DNN) versions 5.0.0 to 9.3.0-RC. A big constraint of XmlSerializer is that it doesn’t work with types that have interface members (example: System.Diagnostic.Process). This cookie is used when the application serves a custom 404 Error page, which is also the default setting. Vulnerable versions store profile information for users in the DNNPersonalization cookie as XML. 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). Kev 180 Posted April 3. The application will parse the XML input, deserialize, and execute it. 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. Having both the encrypted and plaintext codes, you can launch a known-plaintext attack and encrypt your payload with the recovered key. A malicioususer can decode one of such cookies and identify who that user is, and possiblyimpersonate other users and even upload malicious code to the server. 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. Malformed data or unexpected data could be used to abuse application logic, deny service, or execute arbitrary code, when deserialized.
