漏洞信息

漏洞名称： Microsoft SharePoint Server Remote Code Execution Vulnerability

漏洞编号：

• CVE： CVE-2025-53770

漏洞类型： 反序列化

漏洞等级： 严重

漏洞描述： Microsoft SharePoint Server是一款广泛使用的企业级协作平台，支持文档管理、内容管理、业务流程自动化等功能，广泛应用于企业内部和外部协作场景。该漏洞存在于SharePoint Server的on-premises版本中，涉及对不可信数据的反序列化处理，攻击者可以通过网络利用此漏洞执行任意代码。漏洞的技术根源在于SharePoint Server在处理特定数据时未能正确验证输入，导致攻击者可以构造恶意数据触发反序列化过程，从而执行任意代码。此漏洞已被发现在野外被利用，攻击者无需认证即可远程利用此漏洞，导致系统完全被控制。由于SharePoint Server通常部署在企业内网中，且具有较高的权限，此漏洞的利用可能导致敏感数据泄露、服务中断等严重后果。微软已经意识到此漏洞的存在，并正在准备和测试全面的更新以解决此漏洞，同时提供了临时的缓解措施建议。
