FKIE_CVE-2025-67722

Vulnerability from fkie_nvd - Published: 2025-12-16 01:15 - Updated: 2026-10-07 19:10
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
FreePBX is an open-source web-based graphical user interface (GUI) that manages Asterisk. Prior to versions 16.0.45 and 17.0.24 of the FreePBX framework, an authenticated local privilege escalation exists in the deprecated FreePBX startup script `amportal`. In the deprecated `amportal` utility, the lookup for the `freepbx_engine` file occurs in `/etc/asterisk/` directories. Typically, these are configured by FreePBX as writable by the **asterisk** user and any members of the **asterisk** group. This means that a member of the **asterisk** group can add their own `freepbx_engine` file in `/etc/asterisk/` and upon `amportal` executing, it would exec that file with root permissions (even though the file was created and placed by a non-root user). Version 16.0.45 and 17.0.24 contain a fix for the issue. Other mitigation strategies are also available. Confirm only trusted local OS system users are members of the `asterisk` group. Look for suspicious files in the `/etc/asterisk/` directory (via Admin -> Config Edit in the GUI, or via CLI). Double-check that `live_dangerously = no` is set (or unconfigured, as the default is **no**) in `/etc/asterisk/asterisk.conf` file. Eliminate any unsafe custom use of Asterisk dial plan applications and functions that potentially can manipulate the file system, e.g., System(), FILE(), etc.

Antes de las versiones 16.0.45 y 17.0.24 del framework de FreePBX, existe una escalada de privilegios local autenticada en el script de inicio obsoleto de FreePBX \u0027amportal\u0027. En la utilidad obsoleta \u0027amportal\u0027, la b\u00fasqueda del archivo \u0027freepbx_engine\u0027 ocurre en los directorios \u0027/etc/asterisk/\u0027. T\u00edpicamente, estos son configurados por FreePBX como escribibles por el usuario asterisk y cualquier miembro del grupo asterisk. Esto significa que un miembro del grupo asterisk puede a\u00f1adir su propio archivo \u0027freepbx_engine\u0027 en \u0027/etc/asterisk/\u0027 y al ejecutarse \u0027amportal\u0027, ejecutar\u00eda ese archivo con permisos de root (aunque el archivo fue creado y colocado por un usuario no-root). Las versiones 16.0.45 y 17.0.24 contienen una soluci\u00f3n para el problema. Otras estrategias de mitigaci\u00f3n tambi\u00e9n est\u00e1n disponibles. Confirme que solo los usuarios de sistema del SO local de confianza son miembros del grupo \u0027asterisk\u0027. Busque archivos sospechosos en el directorio \u0027/etc/asterisk/\u0027 (a trav\u00e9s de Admin  -\u003e  Config Edit en la GUI, o a trav\u00e9s de CLI). Verifique dos veces que \u0027live_dangerously = no\u0027 est\u00e9 configurado (o no configurado, ya que el valor predeterminado es no) en el archivo \u0027/etc/asterisk/asterisk.conf\u0027.
