标题： Microsoft SharePoint Server 授权问题漏洞 (CVE-2025-53771)
描述：Microsoft SharePoint Server是美国微软（Microsoft）公司的一款协作平台。 Microsoft SharePoint Server存在授权问题漏洞，该漏洞源于路径遍历限制不当，可能导致欺骗攻击。
描述
Microsoft Office SharePoint Server contains an improper authentication vulnerability that allows unauthorized attackers to perform spoofing over a network. By crafting a POST request to /_layouts/15/ToolPane.aspx with a forged Referer header (/_layouts/SignOut.aspx), attackers can bypass authentication mechanisms and gain unauthorized access to protected endpoints. This vulnerability is part of the ToolShell exploit chain and is a patch bypass for CVE-2025-49706. When chained with CVE-2025-53770 (deserialization vulnerability), it enables unauthenticated remote code execution on SharePoint Server.
