Vulnerability from variot

The default configuration of the HP CM8060 Color MFP with Edgeline; Color LaserJet 3xxx, 4xxx, 5550, 9500, CMxxxx, CPxxxx, and Enterprise CPxxxx; Digital Sender 9200c and 9250c; LaserJet 4xxx, 5200, 90xx, Mxxxx, and Pxxxx; and LaserJet Enterprise 500 color M551, 600, M4555 MFP, and P3015 enables the Remote Firmware Update (RFU) setting, which allows remote attackers to execute arbitrary code by using a session on TCP port 9100 to upload a crafted firmware update. HP Printers and Digital Senders are prone to a security-bypass vulnerability. An attacker may leverage the issue to remotely install malicious printer firmware. The unauthorized firmware could also cause a Denial of Service to the device. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed. Please refer to the RESOLUTION below for a list of impacted products. A firmware update can be sent remotely to port 9100 without authentication.

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. Firmware updates for any of the products can also be downloaded as follows.

Browse to www.hp.com/go/support then:

Select "Drivers & Software" Enter the product name listed in the table above into the search field Click on "Search" If the search returns a list of products click on the appropriate product Under "Select operating system" click on "Cross operating system (BIOS, Firmware, Diagnostics, etc.)" If the "Cross operating system ..." link is not present, select any Windows operating system from the list. Select the appropriate firmware update under "Firmware"
