CVE-2025-49706 is an improper authentication vulnerability in Microsoft SharePoint Server that enables network-based spoofing. Successful exploitation can expose sensitive information and permit changes to disclosed information. It forms the authentication-related component of the original ToolShell exploit chain with CVE-2025-49704, enabling unauthorized access and remote code execution against on-premises SharePoint servers. Associated affected editions include SharePoint Enterprise Server 2016, SharePoint Server 2019, and SharePoint Server Subscription Edition. CVE-2025-53771 is a bypass of the initial patch for CVE-2025-49706.

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.
