our organization has a RICOH Pro C7200SX printer, and I’m strongly suspecting Greenbone caused it to print lots of garbage pages today.
I suspect that the printer isn’t recognized by Greenbone?
Expected/desired result: the printer should be recognized by Greenbone and should be ignored.
My question is: can you look at whether Greenbone is lacking detection for this specific printer? If so, hopefully the information below helps you implement the proper detection.
Thanks in advance.
It printed about 20-50 pages with mostly binary garbage (usually just a few lines), and one page contained a simple HTTP GET request (it was only 3-5 lines, not very informative).
We are using the ‘Full and fast’ scan config, and the ‘Exclude printers from scan’ option is set to ‘Yes’.
We haven’t had this before, so I’m guessing it may be due to something that has recently been introduced via the feed updates?
In case it’s relevant, these are our current feed dates:
20210908 - Greenbone Community Feed
20210903 - Greenbone Community SCAP Feed
20210903 - Greenbone Community CERT Feed
20210809 - Greenbone Community gvmd Data Feed
Here’s the output of various protocols, to help you detect the printer in Greenbone:
