The third time is charm saying goes but not when we are talking about Microsoft. Print spooler is again in focus, in a bad way. This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw came to light shortly after and was subsequently patched (with mixed success). Microsoft is once again advising its customers to disable Windows print spooler after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

"An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights."

Stop this service right away or you are risking a potential attack.

1. Press ⊞ WINDOWS + X to open the hidden menu
2. Click on Power Shell (admin)
3. In Power Shell type in the following command to check if spool service is running: Get-Service -Name Spooler followed by ENTER
4. If spooler service is running type in the next command to stop it: Stop-Service -Name Spooler –Force and press ENTER
5. Then follow with this command to disable it at startup: Set-Service -Name Spooler -StartupType Disabled followed with ENTER

That’s it, we hope a patch will come soon for all the people that are using network printing and indeed need this service running in order to do work.
