Description

On Asterisk, prior to versions 18.24.2, 20.9.2, and 21.4.2 and certified-asterisk
versions 18.9-cert11 and 20.7-cert2, an AMI user with 'write=originate' may change
all configuration files in the '/etc/asterisk/' directory. Writing a new extension
can be created which performs a system command to achieve RCE as the asterisk service
user (typically asterisk).
Default parking lot in FreePBX is called "Default lot" on the website interface,
however its actually 'parkedcalls'.
Tested against Asterisk 19.8.0 and 18.16.0 on Freepbx SNG7-PBX16-64bit-2302-1.
