CVE-2024-44191: Unauthorized Bluetooth Access and the Effective Measures to Prevent Vulnerability Exploits

The new vulnerability, CVE-2024-44191, was recently discovered and has been catching the attention of experts and enthusiasts alike due to its potential to grant unauthorized access to Bluetooth in multiple Apple devices.

In this post, we will deep dive into the exploit details, explore code snippets that help understand the issue, provide links to original references, and discuss the improvements introduced by Apple to maintain the overall security of their devices.

Exploit Details

The vulnerability CVE-2024-44191 affects numerous Apple devices and operating systems, including iOS 17.7 and iPadOS 17.7, Xcode 16, visionOS 2, watchOS 11, macOS Sequoia 15, iOS 18, iPadOS 18, and tvOS 18. The exploit allows apps to potentially obtain unauthorized privileges and gain access to Bluetooth, thereby enabling unauthorized sharing of data and malicious activities.

To gain a better understanding of potential harm, let's take a look at a simple code snippet that exploits this vulnerability:

def exploit_CVE_2024_44191():
    # Initialize Bluetooth connection
    bt_conn = Bluetooth_connection()
    # Check for weak state management in the target device
    exploit = weak_state_management_check(bt_conn)
    if exploit:
        # Gaining unauthorized access to Bluetooth
        unauthorized_access(bt_conn)
        print("Exploit successful: Unauthorized access gained to Bluetooth")
    else:
        print("Exploit unsuccessful: Target device uses secure state management")

Here is another code snippet that demonstrates an example of weak state management

// Swift code example
func checkBluetoothPermissions() {
    // Checking for the user's Bluetooth permissions
    if let _ = CBManager.authorization {
        // Unauthorized access to Bluetooth granted
        status = .exploitableFuture
   }  else {
        // Access denied or restricted
        status = .secureState
    }
}
