CVE-2023-45894Network attack vector

Unauthenticated remote code execution via kiosk breakout

Published Dec 14, 2023 · Updated Aug 2, 2024

Remote code execution in Parallels Remote Application Server before 19.2.23975 allows remote attackers to execute code via kiosk breakout. The server fails to segment virtualized applications from the host, so standard kiosk-breakout actions escape the application boundary and run commands on the server. The attack is unauthenticated over the network and can compromise confidentiality, integrity, and availability; the record does not identify a narrower precondition.
