CVE-2024-8272

Root privilege escalation via unchecked XPC client

Published Nov 25, 2024 · Updated Nov 25, 2024

Missing authorization in Universal Audio UA Connect 2.7.0 and earlier allows local users to execute privileged operations as root. The com.uaudio.bsd.helper XPC handler accepts any client's connection, reads its command key, and performs file, ownership, permission, and package operations without verifying code requirements, entitlements, or security flags. A low-privileged macOS account can place a LaunchDaemon property list that executes an arbitrary payload as root after restart.
