CVE Name CVE-2022-42706
AMI Users with config permissions may read files outside of A
Description sterisk directory via GetConfig AMI Action even if
live_dangerously" is set to "no"
Modules manager
Affected
The Asterisk Manager Interface has been modified to respect the
Asterisk "live_dangerously" flag for GetConfig actions and will now
prevent access to files outside of the Asterisk configuration
Resolution directory if "live_dangerously" is set to "no". Administrators
should upgrade to the latest version of Asterisk to get this
capability and should also remove the "config" permission from
manager users who don't need it.
