Overview
CVE-2023-28910 is a critical vulnerability found within the Bluetooth stack of the MIB3 infotainment system, predominantly used in Skoda Superb III cars. The flaw has the potential to bypass assertion functions due to a disabled abortion flag, leading to possible system compromise or data leakage. This vulnerability is of concern to all users of MIB3 infotainment systems, particularly those with the Skoda Superb III car featuring the OEM part number 3V0035820. It is crucial to understand the nature of this vulnerability and the resulting implications to ensure the security of these systems.

How the Exploit Works
The exploit manipulates the Bluetooth stack of the MIB3 infotainment system. The system has a specific flaw arising from disabling the abortion flag. This disabled flag allows for the bypass of assertion functions within the system, which could lead to a potential security compromise. An attacker, once paired with the Bluetooth system, could potentially exploit this flaw to gain unauthorized access to the system or leak sensitive data.
Conceptual Example Code
This section does not provide a real exploit but a conceptual example of how the vulnerability could be exploited. This could involve a sequence of Bluetooth commands, which, when issued in a specific order, lead to the bypass of assertion functions. The example below is a hypothetical Bluetooth command sequence:
$ bluetoothctl
[bluetooth]# pair <device_address>
[bluetooth]# connect <device_address>
[bluetooth]# send-command <malicious_command_sequence>This command sequence represents an initial pairing with the device, establishing a connection, and then sending a hypothetical malicious command sequence that could exploit the vulnerability.
Please note that the “malicious_command_sequence” is a placeholder for a potential command or sequence of commands that could bypass the assertion functions. The exact nature of this command would depend on the specifics of the vulnerability and the implementation of the Bluetooth stack in the affected system.
