Some FutureSmart printers have two available firmware platforms - FutureSmart 3 (FS3) and FutureSmart 4 (FS4). Select the appropriate firmware version for the required FutureSmart platform.

Step 2: Enable Extended Signature Verification

Open the printer EWS, click the General tab, click the Solution Installer page, then locate the Solution Verification Settings section.
Select the checkbox for Enable Extended Signature Verification.

Temporary mitigation settings

The vulnerability can be prevented in the short term by the following actions:

Open the printer EWS, click the Security tab, then locate the Local Administrator Password section.
Set the Local Administrator password.
Under the Firmware Upgrade Security section, disable the Allow firmware upgrades sent as print jobs (Port 9100) setting.
Click the General tab, click the Solution Installer page, then locate the Solution Verification Settings section.
Select the checkbox for Enable Extended Signature Verification.

These recommendations are documented in HP Printing Security Best Practices for HP LaserJet Enterprise Printers.

See page 35 for EWS administrator password configuration.
See page 37 for Allow firmware upgrades sent as print jobs configuration.
