CVE-2017-9822 is an insecure deserialization vulnerability in DNN (DotNetNuke) before version 9.1.1. DNN processes personalization data supplied in the DNNPersonalization cookie and extracts an attacker-controlled XML type attribute to construct an XmlSerializer using that type as the expected type. This allows an attacker to select types and invoke property setters or other gadget-chain entry points during deserialization, potentially resulting in arbitrary code execution in the DNN application context.

This repository contains a single Metasploit module targeting a deserialization vulnerability in DotNetNuke (DNN) versions 5.0.0 to 9.3.0-RC. The exploit abuses the DNNPersonalization cookie, which is processed by the application when handling user profile data, especially during 404 error handling. By crafting a malicious serialized .NET object (optionally encrypted and base64-encoded), the attacker can trigger arbitrary code execution on the Windows server. The module supports multiple DNN versions, handling differences in encryption and session requirements. The payload is typically a PowerShell command that opens a reverse shell or executes arbitrary code. The main network endpoint is the DNN web application, with the default trigger path set to '/__'. The exploit is weaponized, as it is part of the Metasploit framework and supports customizable payloads. The code is well-structured, with clear separation of payload creation, encryption, and delivery logic.
