Crashing In-Flight Entertainment System via USB Port

The British Airways Entertainment System installed on Boeing 777-36N(ER) and possibly other aircraft, is vulnerable to a privilege escalation flaw tracked as CVE-2019-9019. The bug resides in the USB Handler component, which does not restrict the USB charging/data-transfer feature from interacting with the USB keyboard and mouse devices. A local unauthenticated attacker can therefore hack the entertainment applications such as using mouse copy-and-paste actions to trigger a Chat buffer overflow. There is no technical details or public exploit available at the time of report.
