CVE-2024-8287

Instance interaction via unvalidated stream-agent certificate

Published Sep 18, 2024 · Updated Sep 19, 2024

Improper certificate validation in Canonical Anbox Cloud 1.17.0 through 1.23.0 allows man-in-the-middle attackers to access instances. AMS relays a JSON-supplied stream-agent endpoint and certificate fingerprint to an Anbox instance, which connects without enforcing that fingerprint. Exploitation requires internal-network access and control of the instance’s outbound connections, exposing WebRTC signaling data and instance interaction.
