CVE-2025-49706 is an improper-authentication vulnerability in on-premises Microsoft SharePoint. The flaw occurs in SharePoint request authentication handling, where logic associated with sign-out referrers can cause requests to be treated incorrectly. Reported exploitation used a Referer value identifying a SharePoint SignOut.aspx endpoint to bypass authentication controls for ToolPane requests. Microsoft characterized the vulnerability as network-based spoofing by an authorized attacker; it was also used in the ToolShell exploit chain with CVE-2025-49704. The original July 2025 fix was bypassed, leading to the replacement patch tracked as CVE-2025-53771.

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.
