asterisk: Asterisk is an open-source private branch exchange (PBX)
CVE-2025-47780 is fixed in asterisk on 1 platform by DEBIAN-CVE-2025-47780 (version 1:22.4.1~dfsg+~cs6.15.60671435-1), released May 22, 2025. It is not reported as exploited. Patch Radar priority: High.
Asterisk is an open-source private branch exchange (PBX). Prior to versions 18.26.2, 20.14.1, 21.9.1, and 22.4.1 of Asterisk and versions 18.9-cert14 and 20.7-cert5 of certified-asterisk, trying to disallow shell commands to be run via the Asterisk command line interface (CLI) by configuring `cli_permissions.conf` (e.g. with the config line `deny=!*`) does not work which could lead to a security risk. If an administrator running an Asterisk instance relies on the `cli_permissions.conf` file to work and expects it to deny all attempts to execute shell commands, then this could lead to a security vulnerability. Versions 18.26.2, 20.14.1, 21.9.1, and 22.4.1 of Asterisk and versions 18.9-cert14 and 20.7-cert5 of certified-asterisk fix the issue.
