Descriptions

An issue was discovered in channels/chan_sip.c in Sangoma Asterisk 13.x before 13.29.2, 16.x before 16.6.2, and 17.x before 17.0.1, and Certified Asterisk 13.21 before cert5. A SIP request can be sent to Asterisk that can change a SIP peer's 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 peer's 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.

Se ha descubierto un problema en channels/chan_sip.c en Sangoma Asterisk 13.x antes de 13.29.2, 16.x antes de 16.6.2, y 17.x antes de 17.0.1, y Certified Asterisk 13.21 antes de cert5. Una solicitud SIP puede ser enviada a Asterisk que puede cambiar la dirección IP de un peer SIP. Un REGISTRO no necesita ocurrir, y las llamadas pueden ser secuestradas como resultado. Lo único que se necesita conocer es el nombre del peer; los detalles de autenticación como las contraseñas no necesitan ser conocidos. Esta vulnerabilidad sólo es explotable cuando la opción nat está configurada por defecto, o auto_force_rport
