Parse 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. 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. Affects DotNetNuke versions 5.0.0 to 9.1.0. 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 … Just continue searching until you find a positive integer). You can start by analyzing the vulnerable source code of how the application processes the DNNPersonalization cookie XML value. Because the XML cookie value can be user-supplied through the request headers, you can control the type of the XmlSerializer. 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. The registration code is the encrypted form of the portalID and userID variables used within the application, disclosed in plaintext through the user profile. 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. In recent weeks we have noted a significant increase in the numbers of exploit attempts targeting two specific vulnerabilities: CVE-2017-5638 (a vulnerability in Apache Struts) and CVE-2017-9822 (a vulnerability in DotNetNuke).
