CVE-2017-14100 Information

Description

In Asterisk 11.x before 11.25.2 13.x before 13.17.1 and 14.x before 14.6.1 and Certified Asterisk 11.x before 11.6-cert17 and 13.x before 13.13-cert5 unauthorized command execution is possible. The app_minivm module has an \externnotify\ program configuration option that is executed by the MinivmNotify dialplan application. The application uses the caller-id name and number as part of a built string passed to the OS shell for interpretation and execution. Since the caller-id name and number can come from an untrusted source a crafted caller-id name or number allows an arbitrary shell command injection.
