VAR-202012-1499

Vulnerability from variot - Updated: 2025-01-30 20:01

Kia Motors Head Unit with Software version: SOP.003.30.18.0703, SOP.005.7.181019, and SOP.007.1.191209 may allow an attacker to inject unauthorized commands, by executing the micomd executable deamon, to trigger unintended functionalities. In addition, this executable may be used by an attacker to inject commands to generate CAN frames that are sent into the M-CAN bus (Multimedia CAN bus) of the vehicle. Kia Motors Head Unit Is vulnerable to incorrect default permissions.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state
