FreePBX 是一款开源的 IP PBX（电话交换机）系统。在 16.0.4 和 17.0.6 版本之前，FreePBX 的“等待音乐”（Music on Hold，简称 MoH）模块存在一个严重的安全漏洞，允许经过身份验证的攻击者以 Asterisk 服务的权限执行任意系统命令。利用该漏洞的前提是攻击者需拥有现有的 FreePBX 管理员账户权限。 该漏洞的根本原因在于，MoH 模块接受一个 POST 参数，用于定义自定义的 Asterisk 应用程序，但该参数在被存入数据库时未经任何清洗或过滤处理。随后，这些

Vulnerability Title
FreePBX: Authenticated Remote Code Execution in FreePBX Music on Hold (MoH) Module
Source: CVE Program / CVE List V5
Vulnerability Description
FreePBX is an open source IP PBX. Prior to versions 16.0.4 and 17.0.6, the FreePBX Music on Hold (MoH) module contains a critical security flaw that allows authenticated attackers to execute arbitrary system commands with the privileges of the Asterisk service. Authentication with an existing FreePBX administrator account is required. The root cause lies in the fact that the module accepts a POST parameter that defines a custom Asterisk application, which is then stored in the database without any sanitization. Later, this data is written directly to the musiconhold_additional.conf configuration file without validation. Since Asterisk reads this configuration file and executes the specified application, an attacker can inject arbitrary commands that will be executed with Asterisk's permissions. This issue has been patched in versions 16.0.4 and 17.0.6.
