This repository provides a working exploit for CVE-2024-29059, a vulnerability in ASP.NET web applications using .NET Remoting over HTTP. The exploit consists of a Python script (RemoteApplicationMetadata.py) that automates the process of leaking ObjRef URIs from a vulnerable server and delivering deserialization payloads using either SOAP or binary .NET Remoting formats. The repository includes example SOAP payloads (in the Payloads directory) that use the TextFormattingRunProperties gadget to manipulate HTTP response headers (e.g., setting cookies or redirect locations). The exploit targets ASP.NET applications running on .NET Framework 4.5.2 with Application Insights enabled and a specific configuration that re-enables vulnerable remoting behavior. The main attack vector is network-based, exploiting HTTP endpoints exposed by the target application. The repository also contains a sample vulnerable web application (WebApplication452) for testing purposes. The exploit is operational, providing both the means to leak sensitive ObjRef URIs and to deliver arbitrary deserialization payloads, which can be adapted for further exploitation depending on available gadgets.
