Chaining web security vulnerabilities

When adversaries target a type of IoT device, multiple vulnerabilities are often used in weaponizing an exploit. These vulnerabilities may be low in criticality by themselves; however, when combined, the exploit impact is much greater. It is not uncommon for a combination of low vulnerabilities to escalate into a critical vulnerability. This is especially important with regard to IoT devices. One critical bug discovered in an IoT device can compromise the integrity of the device. This recipe will cover how to chain web security vulnerabilities together to gain access to a Subaru-connected vehicle without a key fob, car keys, or credentials.

Note

It is important that any vulnerability research stays within legal grounds. Performing unauthorized testing against MySubaru accounts and Subaru servers is illegal. All testing should take place in a controlled environment and should be rightfully owned. Although Subaru remote services do not control engine and...
