Description

Details for this vulnerability have not been published by NIST at this point. Descriptions from software vendor advisories for this issue are provided below.

From VID-A8D94711-0D03-11EA-87CA-001999F8D30B:

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.
