In this post, we delve deep into the recently discovered Windows Mobile Broadband Driver Remote Code Execution vulnerability, dubbed CVE-2024-29997. The vulnerability is categorized as a critical flaw, with attackers potentially exploiting it remotely to execute arbitrary code on a victim's system. We strive to provide a comprehensive understanding of the exploit, disclosure timelines, details of vulnerable systems, steps to reproduce, mitigation of risk, and related references.

Background

The vulnerability (CVE-2024-29997) was discovered in the Windows Mobile Broadband Driver, which is responsible for managing the communication between cellular data devices and the Windows operating system. The flaw allows an attacker to send specially crafted payloads to the driver, resulting in a remote code execution vulnerability.

Exploit Details

An attacker exploits the vulnerability by sending malicious payloads to the Windows Mobile Broadband Driver. The specially crafted payload can cause a buffer overflow, leading to remote code execution.

Here's a high-level overview of the steps involved in reproducing the vulnerability

1. Identify the target system running a vulnerable Windows version and has the Mobile Broadband Driver enabled.

Send the payload to the target system using a suitable attack vector.

5. Upon successful exploitation, gain access to the target system with arbitrary code execution capabilities.

The following code snippet demonstrates a possible malicious payload exploiting the vulnerability (for educational purposes only, do not use for any malicious activities):

# Sample malicious payload for CVE-2024-29997
import socket

target_ip = "TARGET_IP_ADDRESS"
target_port = 12345

# Craft the malicious payload
payload = "A" * 256 + "B" * 4 + "\x90" * 16 + "SHELLCODE"

# Establish connection and send payload
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((target_ip, target_port))
sock.send(payload)
sock.close()

It's crucial to note that the provided code snippet is for educational purposes only and should not be used for any real-world exploitation.

To protect your systems from this vulnerability, you should do the following

1. Apply the security update released by Microsoft, which addresses the vulnerability (link: https://www.microsoft.com/security/updates/).

3. Use secure network practices, such as firewall protection and intrusion detection, to minimize the potential attack vectors for this vulnerability.

Conclusion

In conclusion, CVE-2024-29997 represents a critical security issue, as it enables remote code execution on a victim's system via the Windows Mobile Broadband Driver. It's essential to prioritize the security update addressing this vulnerability and remain vigilant with system updates and network security measures. Stay informed about the latest security threats and ensure that your organization's IT infrastructure is protected.
