DESCRIPTION:
A security issue has been reported in various HP LaserJet Printers
and HP Digital Senders, which can be exploited by malicious people to
bypass certain security restrictions.
The security issue is caused due to an error within the Remote
Firmware Update (RFU) mechanism, which does not check for
authentication when handling firmware updates. This can be exploited
to upload a malicious firmware to device via a specially crafted
request to TCP port 9100.
Please see the vendor's advisory for the list of affected products.
SOLUTION:
Disable the "Printer Firmware Update" setting.
PROVIDED AND/OR DISCOVERED BY:
Salvatore Stolfo and Ang Cui, Columbia University.
