Asterisk Project Security Advisory - Manager users can execute arbitrary shell commands with the MixMonitor manager action. Asterisk does not require system class authorization for a manager user to use the MixMonitor action, so any manager user who is permitted to use manager commands can potentially execute shell commands as the user executing the Asterisk process.
