CVE-2025-49704 is a code-injection vulnerability in on-premises Microsoft SharePoint Server that allows an authorized attacker to execute code over a network. It affects SharePoint Enterprise Server 2016, SharePoint Server 2019, and SharePoint Server Subscription Edition. The vulnerability forms the remote-code-execution component of the original ToolShell exploit chain when combined with CVE-2025-49706, an authentication-related flaw. The chain enables unauthorized server access, exposure of internal configurations, and remote code execution. CVE-2025-53770 is a patch bypass for CVE-2025-49704. The vulnerability has been actively exploited, including in ransomware campaigns.

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.
