Fax vulnerability in HP all-in-one printers


A vulnerability was recently disclosed by Check Point Software Technologies Ltd. wherein the fax protocol was exploited on a Hewlett Packard all-in-one printer to take control of the device by sending a crafted fax via telephone line and then gain access to the connected network.

Because the vulnerability is part of the fax protocol itself, it's suspected that devices from other manufacturers may also be susceptible to this kind of attack.

The majority of Ricoh multifunction devices are not affected by this vulnerability because our fax implementation does not include the JPEG processing exploited in this case.

The remaining devices listed below are currently under investigation.

SP 3600SF/3610SF
Aficio SP 1200SF
Aficio SP 4410SF/4420SF
We will continue to monitor this situation and take any appropriate action necessary to ensure the security of our devices.


Next Update
