三、修复建议
版本升级
使用office365/office 2019/2021的用户可以通过升级到15225.20204来缓解该漏洞的影响
通过更新可以缓解Office的攻击入口向量,但并不能修复MSDT漏洞。用户可以使用360针对MSDT漏洞实现全方位拦截。
升级方式如下:
1.打开任何Office应用程序,例如Word或Excel。
2.选择文件>帐户。
3.选择Office更新->立即更新
查看当前版本方式如下:
1.打开任何Office应用程序,例如Word或Excel。
2.选择文件>帐户。
3.在“产品信息”下,记下“关于”部分下的版本号。
禁用MSDT URL协议
禁用MSDT URL协议可防止故障排除程序作为链接启动,包括整个操作系统的链接。仍然可以使用“获取帮助”应用程序和系统设置中的其他或附加故障排除程序来访问故障排除程序。请按照以下步骤禁用:
1.以管理员身份运行命令提示符。
2.要备份注册表项,请执行命令“reg export HKEY_CLASSES_ROOT\ms-msdt filename ”
3.执行命令“reg delete HKEY_CLASSES_ROOT\ms-msdt /f”。
如何撤消解决方法
1.以管理员身份运行命令提示符。
2.要恢复注册表项,请执行命令“reg import filename”
