PrintNightmare Vulnerability - Initial update and advice

Microsoft is warning Windows users about an unpatched critical flaw in the Windows Print Spooler service. The vulnerability, dubbed PrintNightmare, was uncovered earlier this week after security researchers accidentally published a proof-of-concept (PoC) exploit. Microsoft have not yet released a fix in the form of an update/patch – however disabling the print spooler service on domain controllers is a mitigation and should be actioned as soon as possible. 

FIT clients will be contacted soon regarding remediation steps and updates.
