A permission escalation flaw was found in the way Asterisk, an open-source telephony toolkit, performed user permission checks (only Asterisk System class user should be able to run shell commands if that user had System class authorization). Due to a bug, an Asterisk manager interface user could bypass the security check and execute shell commands by using the MixMonitor application with the originate action or by using the GetVar or Status manager actions in the combination with SHELL and EVAL functions.
