-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c03102449 Version: 5 HPSBPI02728 SSRT100692 rev.5 - Certain HP Printers and HP Digital Senders, Remote Firmware Update Enabled by Default NOTICE: The information in this Security Bulletin should be acted upon as soon as possible. Release Date: 2011-11-30 Last Updated: 2012-03-19 Potential Security Impact: Remote firmware update enabled by default Source: Hewlett-Packard Company, HP Software Security Response Team VULNERABILITY SUMMARY A potential security vulnerability has been identified with certain HP printers and HP digital senders. The vulnerability could be exploited remotely to install unauthorized printer firmware. References: CVE-2011-4161 SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed. Please refer to the RESOLUTION below for a list of impacted products. BACKGROUND CVSS 2.0 Base Metrics =========================================================== Reference Base Vector Base Score CVE-2011-4161 (AV:N/AC:L/Au:N/C:C/I:C/A:C) 10.0 =========================================================== Information on CVSS is documented in HP Customer Notice: HPSN-2008-002 Note: For further information on Secure Printing and Imaging please refer to http://www.hp.com/go/secureprinting Remote Firmware Update (RFU): The Remote Firmware Update (RFU) feature is enabled by default. A firmware update can be sent remotely to port 9100 without authentication. This could allow unauthorized modification of the device firmware. The unauthorized firmware could impact the confidentiality and integrity of data sent to and received from the device. The unauthorized firmware could also cause a Denial of Service (DoS) to the device. RESOLUTION The following steps can be taken to avoid unauthorized firmware updates: Update the firmware to a version that implements code signing Disable the Remote Firmware Update The code signing feature verifies that firmware updates are properly signed. This will prevent the installation of invalid firmware updates. Note: A firmware update may be required to allow the RFU to be disabled or to implement code signing. Code signing is not available on all the affected devices. Please refer to the following table.
