Description
Waves Central for macOS versions 13.0.9 through 16.5.5 contain a local privilege escalation vulnerability in the privileged helper service. The helper validates connecting XPC clients using the client process identifier (PID) to verify code-signing identity. Because process identifiers can be reused, a local attacker can exploit a race condition between the time a connection request is made and the time the helper performs validation, causing the helper to trust an attacker-controlled process. This allows the attacker to invoke privileged operations, resulting in arbitrary code execution as root. The issue is fixed in version 16.6.2.
