Description Jan Lieskovsky 2011-04-22 09:35:53 UTC

An Asterisk Manager Interface security check bypass was found in the way
Asterisk performed user access check during the originate manager action.
A remote authenticated user, with manager privilege, could use this flaw
to escalate their privileges and execute arbitrary shell commands via an
'Async' header sent together with 'Application' header during the manager
Originate action.
