0x00 漏洞背景

2019年8月14日微软发布的安全更新中除了RDP漏洞还涵盖了针对多个远程代码执行高危漏洞的修复。

  • Microsoft Word远程代码执行漏洞, 漏洞编号CVE-2019-0585。

  • LNK远程代码执行漏洞,漏洞编号CVE-2019-1188。

 

0x01 漏洞详情

  • LNK远程代码执行漏洞CVE-2019-1188

这个LNK远程代码执行漏洞和之前Stuxnet利用的LNK漏洞及其绕过类似。如果系统处理了攻击者准备的.LNK文件,则攻击者可能可以远程执行代码。攻击者可以通过可移动驱动器(如U盘)或者远程共享的方式攻击。

该漏洞影响下列版本的操作系统:

Windows 10 Version 1709 for 32-bit Systems
Windows 10 Version 1709 for 64-based Systems
Windows 10 Version 1709 for ARM64-based Systems
Windows 10 Version 1803 for 32-bit Systems
Windows 10 Version 1803 for ARM64-based Systems
Windows 10 Version 1803 for x64-based Systems
Windows 10 Version 1809 for 32-bit Systems
Windows 10 Version 1809 for ARM64-based Systems
Windows 10 Version 1809 for x64-based Systems
Windows 10 Version 1903 for 32-bit Systems

Windows Server, version 1903 (Server Core installation)

  • Microsoft Word远程代码执行漏洞CVE-2019-0585

大多数word补丁被评为Important,但这一个被评为Critical。通常的word漏洞需要受害者在word中打开存在漏洞的word文档。对于这个漏洞攻击媒介是Outlook预览窗格,因此攻击者需要将准备的word文档或者其链接通过电子邮件发送给受害者,如果受害者在Outlook预览窗格中打开则可能利用此漏洞执行任意代码。

该漏洞影响下列版本的office:

Microsoft Office 2010 Service Pack 2 (32-bit editions)
Microsoft Office 2010 Service Pack 2 (64-bit editions)
Microsoft Office 2016 for Mac
Microsoft Office 2019 for 32-bit editions

  • Windows DHCP客户端远程代码执行漏洞CVE-2019-0736

如果攻击者向受影响的目标发送一个经过特殊设计的DHCP包,这个漏洞可能允许攻击者执行任意代码。这个过程不涉及用户交互或身份验证,理论上也是蠕虫化的。
