Description​

By default, App Services can be deployed over FTP. If FTP is required for an essential deployment workflow, FTPS should be required for FTP login for all App Services.

If FTPS is not expressly required for the App, the recommended setting is Disabled.

Rationale​

FTP is an unencrypted network protocol that will transmit data - including passwords - in clear-text. The use of this protocol can lead to both data and credential compromise, and can present opportunities for exfiltration, persistence, and lateral movement.

Impact​

Any deployment workflows that rely on FTP or FTPs rather than the WebDeploy or HTTPs endpoints may be affected.

Audit​

From Azure Portal​
  1. Go to the Azure Portal.
  2. Select App Services.
  3. Click on an app.
  4. Select Settings and then Configuration.
  5. Under General Settings, for the Platform Settings, the FTP state should not be set to All allowed.
From Azure CLI​

List webapps to obtain the ids:

az webapp list

List the publish profiles to obtain the username, password and ftp server url:

From Azure Portal​

  1. Go to the Azure Portal.
  2. Select App Services.
  3. Click on an app.
  4. Select Settings and then Configuration.
  5. Under General Settings, for the Platform Settings, the FTP state should be set to Disabled or FTPS Only.

From Azure CLI​

For each out of compliance application, run the following choosing either disabled or FtpsOnly as appropriate:

az webapp config set --resource-group <resource group name> --name <app name> --ftps-state [disabled|FtpsOnly]

From PowerShell​

For each out of compliance application, run the following:

Set-AzWebApp -ResourceGroupName <resource group name> -Name <app name> -FtpsState <Disabled or FtpsOnly>
