What is CVE-2024-8272?
CVE-2024-8272 is a high-severity missing authorization vulnerability in Universal Audio UAConnect, published on 25 Nov 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The com.uaudio.bsd.helper service, responsible for handling privileged operations, fails to implement critical client validation during XPC inter-process communication (IPC). Specifically, the service does not verify the code requirements, entitlements, or security flags of any client attempting to establish a connection. This lack of proper validation allows unauthorized clients to exploit the service's methods and escalate privileges to root.
