HP LaserJet Printers Flaw Let Attacker Gain Unauthorized Access

According to a security advisory from HP, some HP Enterprise LaserJet and HP LaserJet Managed printers may be susceptible to information exposure when IPsec is enabled with FutureSmart version 5.6.

All HP Enterprise devices run HP FutureSmart firmware, making it simple to administer and maintain various features across your fleet, from the user experience to app security support.

Users can operate and set up printers using a control panel located at the printer or a web browser for remote access.

The IP network security protocol suite, IPsec (Internet Protocol Security), is used in business networks to secure internal and external communications and stop unwanted access to resources, such as printers.

A critical rating and a CVSS v3.1 score of 9.1 have been given to the issue, tracked as CVE-2023-1707.

Indeed, HP has not yet released a fix for the concerned firmware. According to HP, a new firmware version that rectifies the problem should be available in 90 days.

Notably, the information disclosure flaw in this condition could give an attacker access to sensitive information sent between the affected HP printers and other networked devices.
