VuXML ID	a8d94711-0d03-11ea-87ca-001999f8d30b
Discovery	2019-10-17
Entry	2019-11-22

The Asterisk project reports:

A SIP request can be sent to Asterisk that can change a SIP peers IP address. A REGISTER does not need to occur, and calls can be hijacked as a result. The only thing that needs to be known is the peers name; authentication details such as passwords do not need to be known. This vulnerability is only exploitable when the nat option is set to the default, or auto_force_rport.
