CVE Descriptions

The Group Policy Security Configuration policy implementation in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows man-in-the-middle attackers to disable a signing requirement and trigger a revert-to-default action by spoofing domain-controller responses, aka "Group Policy Security Feature Bypass Vulnerability."

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

# Exploit Title: Microsoft Windows Server 2012 - 'Group Policy' Security Feature Bypass # 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-2015-0009 # Type: Remote # Platform: Windows # Description: This exploit code targets vulnerable systems in order to corrupt GPO updates which causes # the target system to revert various security settings to their default settings. This includes SMB server # and network client settings, which by default do not require SMB signing except for domain controllers. # Successful exploitation against a system with a hardened configuration that requires SMB Signing by the # network client will make the target system vulnerable to MS15-011, which can lead to remote code execution. #!/usr/bin/python3 import argparse import fcntl import os import socket import struct import subprocess from subprocess import PIPE import re # MS15-014 Exploit. # For more information and any updates/additions this exploit see the following Git Repo: https://github.com/Freakazoidile/Exploit_Dev/tree/master/MS15-014 # Example usage: python3 ms15-014.py -t 172.66.10.2 -d 172.66.10.10 -i eth1 # Example usage with multiple DC's: python3 ms15-014.py -t 172.66.10.2 -d 172.66.10.10 -d 172.66.10.11 -d 172.66.10.12 -i eth1 # Questions @Freakazoidile on twitter or make an issue on the GitHub repo.
