Fortigate Vulnerability Scan Makes Samsung Printer Print Jibberish

Not sure if this is the right area but I figured since it is the Vulnerability scan that is built into the Fortigate I might as well post it. Scheduled some weekly vulnerability scans on my home network using the integrated vulnerability scanner on the Fortigate.

 

Well, I was in the restroom just now (12:30 at night my time) and I heard a printer kick off...I didn't know it was my printer at first so I ran in there ready to go toe to toe with an intruder.

 

Saw it was the printer and took a look. My Samsung printer was printing out random jibberish pages and one of them said "Rand-Test-User-Fortinet" a bunch of jibberish and then Squelda

 

After some digging into the firewall I realized it was running a scan.

 

I then remember that my main office experienced the same thing last week when the scan was going off at HQ (HQ also uses a Samsung printer). Needless to say, don't freak out if you run a Samsung style printer and your fortigate vulnerability scans your network and causes it to print some jibberish etc. You will be wasting paper but don't be alarmed haha.

Is this still a thing in FortiOS 6.0 / 6.2?

 

Previous post - get your unit updated to a supported / secure build???

Hi James,

 

Upgrade is unfortunately not a solution for me :(

 

Cheers,

Under 5.2 it seems the only work around is to set up multiple netscan assets to scan around certain IP addresses. 

 

Alternately is to perhaps configure the printer(s) in question to go "offline" during certain times and/or set up authorize access, to say this "(insert Fortigate's local IP address)" is not authorized to access this printer during these hours (set times for local vulnerability scanner hours).
