GNS3 ubridge through 0.9.18 on macOS, as used in GNS3 server before 2.1.17, allows a local attacker to read arbitrary files because it handles configuration-file errors by printing the configuration file while executing in a setuid root context.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
