CVE-2020-28656 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. The update functionality of the Discover Media infotainment system in Volkswagen Polo 2019 vehicles allows physically proximate attackers to execute arbitrary code because some unsigned parts of a metainfo file are parsed, which can cause attacker-controlled files to be written to the infotainment system and executed as root.. EPSS estimates a 0.33% chance of exploitation in the next 30 days.
