CVE-2025-47780

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.

Summary		(es) Asterisk es una centralita privada (PBX) de código abierto. En versiones anteriores a las 18.26.2, 20.14.1, 21.9.1 y 22.4.1 de Asterisk, y a las 18.9-cert14 y 20.7-cert5 de certified-asterisk, intentar impedir la ejecución de comandos de shell a través de la interfaz de línea de comandos (CLI) de Asterisk configurando `cli_permissions.conf` (por ejemplo, con la línea de configuración `deny=!*`) no funciona, lo que podría suponer un riesgo de seguridad. Si un administrador que ejecuta una instancia de Asterisk depende del archivo `cli_permissions.conf` para funcionar y espera que este deniegue todos los intentos de ejecutar comandos de shell, esto podría provocar una vulnerabilidad de seguridad. Las versiones 18.26.2, 20.14.1, 21.9.1 y 22.4.1 de Asterisk y las versiones 18.9-cert14 y 20.7-cert5 de certified-asterisk solucionan el problema.
