Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-64328 identifies a command injection vulnerability within the FreePBX Endpoint Manager module. Specifically, the flaw resides in the `check_ssh_connect()` function of the Filestore component. This post-authentication vulnerability allows an authenticated attacker to execute arbitrary shell commands as the `asterisk` user on the affected system. This vulnerability impacts FreePBX Endpoint Manager versions 17.0.2.36 and above, prior to version 17.0.3. Reports indicate that a financially motivated hacker group, INJ3CTOR3, has actively exploited CVE-2025-64328 since early December 2025 to deploy a persistent webshell known as "EncystPHP," enabling them to gain administrative control over compromised VoIP systems.

Description: FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. In versions 17.0.2.36 and above before 17.0.3, the filestore module within the Administrative interface is vulnerable to a post-authentication command injection by an authenticated known user via the testconnection -> check_ssh_connect() function. An attacker can leverage this vulnerability to obtain remote access to the system as an asterisk user. This issue is fixed in version 17.0.3.
