In other words, built into the Microsoft Windows Operating Systems is the Windows Print Spooler software. For this reason, it temporarily stores print jobs in the computer’s memory until the printer is ready to print them. To print, it schedules the order sent to the print queue. In addition, this service is a default in Windows OS.
To explain, if you have a printer connected to your server or any computer on your LAN or WAN the Windows Print Spooler service is running and you are vulnerable!
On 7th July 2021, Windows released an upgrade, CVE 2021 34527, to address this problem. Run the update on all servers and computers on your LAN or WAN.
