一、漏洞详情

Windows Cloud Files Mini Filter Driver主要用于管理和促进云存储文件的操作。它允许Windows与云存储服务同步，使用户能够直接从本地系统访问、修改和管理其云存储文件。

近日，监测到微软修复了Windows Cloud Files Mini Filter Driver权限提升漏洞(CVE-2023-36036)。Windows Cloud Files Mini Filter Driver在处理Reparse point的过程中，进行memcpy时没有检查数据边界，导致攻击者可以构造恶意Reparse point数据，导致越界写入，具有低权限的本地攻击者利用该漏洞可以将权限提升至SYSTEM。
