HP Inc has posted an update to address a pair of serious security vulnerabilities in its InkJet printers.


The firmware update patches CVE-2018-5924 and CVE-2018-5925, two flaws that can be exploited by printing a file that triggers a stack or static buffer overflow, giving you the ability to then execute malicious code on the targeted printer.


Discovery of the bugs was credited to HP's in-house Product Security Response Team.


In total, HP says the patch will need to be applied to some 225 different models of inkjet printers across its Pagewide, DesignJet, OfficeJet, Deskjet, and HP Envy product lines.

I applaud HP for joining a Bugbounty program, I only wish Epson would do the same.


Being a member of 'bugcrowd' as a researcher, i did not notice their commitment to its programs pages yet.....maybe its part of a private group which i dont have access too, or part of one of the other bugbounty sites?


Good to see printer manufacturers doing something positive towards securing their hardware in an increasingly hostile environment.


It should help increase sales, especially in the corporate sector which takes security far more seriously.

I know that its quite possible that i will swap out my Epson for a HP as current printer security on my home network seems to be its weakest link in testing.


My Epson has 7 open ports exposed to the WAN (only port 445 is filtered running smbd).....that seems excessive to me for a simple wifi printer!


Thanks for the find John.
