CVE-2025-49706 is an improper-authentication vulnerability in on-premises Microsoft SharePoint Server. A flaw in the PostAuthenticateRequestHandler logic can bypass authentication when an HTTP Referer header matches SharePoint sign-out paths. The issue permits network-based spoofing and can be chained with CVE-2025-49704 as part of the ToolShell exploit chain to obtain unauthenticated remote code execution on vulnerable SharePoint servers.

This repository contains a single Metasploit module, 'sharepoint_toolpane_rce.rb', which exploits unauthenticated remote code execution vulnerabilities in Microsoft SharePoint Server (CVE-2025-49704, CVE-2025-49706, and CVE-2025-53771). The exploit leverages a combination of authentication bypass and unsafe deserialization to execute arbitrary commands as the SharePoint site user. The module constructs a malicious serialized .NET DataSet object, compresses it, and embeds it in a crafted XML payload sent via a POST request to the '/_layouts/15/ToolPane.aspx' endpoint. The exploit is unauthenticated and weaponized, allowing for custom command execution. The code is written in Ruby and is structured as a standard Metasploit exploit module, making it easy to use within the Metasploit framework. The repository is highly focused, containing only the exploit module file, and targets vulnerable, unpatched SharePoint Server instances on Windows.
