…will set up a printer called MyPrinter, and pretty much whatever you print to it will end up sitting around, until you print something else, in the intermediate file called spoolfilename.

What the researchers discovered, very greatly simplified, is that with some simple PowerShell commands, any user (not just a system administrator) can setup a new printer device on Windows, provided that there’s already a low-level driver program installed to support the destination printer.īy combining the built-in printer driver called Generic / Text Only (which produces plain old text-only output, as its name suggests) with a local printer spoolfile for temporary output, anyone can set up a “new” printer with any name they like.įor example, a trio of PowerShell commmands of this sort…Īdd-PrinterDriver -Name 'Generic / Text Only'Īdd-Printer -Name MyPrinter -DriverName 'Generic / Text Only' -PortName spoolfilename So it makes sense to write printed output, or to spool it in the jargon, into some intermediate storage for later processing, where it won’t take up system resources such as RAM that would be better used for more pressing and complex tasks. That word almost certainly derives from spools of magnetic or punched tape that were used for intermediate storage in the early days of computing.Ĭomputers are fast but printers are slow and may go offline unpredictably, for example due to a paper jam or the toner running out.

Introducing the spoolerīoth Windows and Unix still use the archaic computing word spooler to describe background software that handles printing jobs. The name “PrintDemon” seems to have given this bug a fearsomeness that it probably doesn’t deserve.

Security researchers Alex Ionescu and Yarden Shafir of technical seminar company Winsider have just published a very lengthy blog post in which they present this bug with the catchy name of PrintDemon.įor those not familiar with Unix, that’s a pun on the word daemon, pronounced “demon” and essentially the same word in a more Greek-like spelling, which is the Linux and Unix equivalent of a Windows service. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted script or application.

An attacker could then install programs view, change, or delete data or create new accounts with full user rights. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. Windows Print Spooler Elevation of Privilege VulnerabilityĪn elevation of privilege vulnerability exists when the Windows Print Spooler service improperly allows arbitrary writing to the file system. However, there’s one apparently minor vulnerability that you may have seen in the media, because it’s created quite a stir: CVE-2020-1048. That includes bugs that could in theory be remotely exploited, for example via rogue attachments or booby-trapped web pages, to implant malware without popping up any dialogs or warnings. Microsoft pushed out fixes for 111 different CVE-tagged vulnerabilities, 16 of which are deemed critical.

This month’s Patch Tuesday fixes just came out in what we’re calling a “ bumper update“.
