Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

FreePBX Endpoint Manager versions 17.0.2.36 through 17.0.2.x contain a post-authentication command injection vulnerability in the filestore module's testconnection/check_ssh_connect() function. An authenticated user with known credentials can inject arbitrary shell commands through this function, executing them as the asterisk system user to obtain remote access.

MitigationUpgrade FreePBX Endpoint Manager to version 17.0.3 or later. Until patched, limit administrative access to trusted users only and monitor for unauthorized access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine the installed Endpoint Manager version
    Run the command: fwconsole ma list | grep endpoint or access Admin > Module Admin in the FreePBX web interface to view the installed version of Endpoint Manager / Sangoma Filestore
    Affected if The displayed version is 17.0.2.36 through 17.0.2.x (any version below 17.0.3)
  2. Confirm the filestore module is installed
    Run: fwconsole ma list | grep filestore or check the FreePBX web interface under Admin > Module Admin for the Filestore module
    Affected if The filestore module appears in the list of installed modules
  3. Verify SSH storage configuration exists
    Navigate to the Endpoint Manager settings in the web interface (Settings > Endpoint Manager > File Store) or inspect the database: mysql -e 'select * from freepbx filestore;' 2>/dev/null to see if any SSH/remote storage configurations are defined
    Affected if SSH or remote storage connections are configured in the filestore module
  4. Check for administrative access to the module
    Review user accounts in FreePBX (Admin > User Management) and verify which accounts have access to the Endpoint Manager or filestore configuration pages
    Affected if Any valid administrative credentials exist that can access the filestore configuration

You are affected if your Endpoint Manager filestore version is 17.0.2.36 or higher but lower than 17.0.3, the filestore module is installed, and an attacker can obtain valid admin credentials to access the filestore configuration interface.

Upgrade available Upgrade to 17.0.3 or later
Fixed in 17.0.3
Interim mitigation

Upgrade FreePBX Endpoint Manager to version 17.0.3 or later. Until patched, limit administrative access to trusted users only and monitor for unauthorized access.

Recommended fix High confidence

FreePBX 17.0.3 or later

  1. 1. Before performing any upgrade, create a complete backup of your FreePBX system including all configurations, recordings, and the asterisk database.
  2. 2. Ensure you have tested backup restoration procedures in a non-production environment.
  3. 3. Access the FreePBX Administrative interface with valid credentials.
  4. 4. Navigate to the module administration or use the built-in upgrade mechanism to update to version 17.0.3 or later.
  5. 5. Alternatively, from the command line as root, run the FreePBX module update commands to upgrade the filestore module: fwconsole ma upgrade filestore
  6. 6. After upgrading, verify the filestore module version is 17.0.3 or higher.
  7. 7. Test the testconnection function to confirm the vulnerability is remediated.
  8. 8. Review user accounts with access to the filestore module and ensure only necessary personnel have administrative access.
