Technical description

An issue was discovered in the Hyundai Gen5W_L in-vehicle infotainment system AE_E_PE_EUR.S5W_L001.001.211214. The AppUpgrade binary file, which is used during the firmware installation process, can be modified by an attacker to bypass the version check in order to install any firmware version (e.g., newer, older, or customized). This indirectly allows an attacker to install custom firmware in the IVI system.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
