Microsoft recently developed an emergency Windows patch after a glitch that threatened to endanger user safety.

Within a few days of identifying the bug, patches were released for Windows Server 2019, Windows Server 2012 R2, Windows Server 2008, Windows 8.1, Windows RT 8.1, and various versions of Windows 10. Although Microsoft has not yet released patches for Windows Server 2012, Windows Server 2016, and Windows 10 Version 1607, the company has given assurances that updates for these versions will be released shortly.

The weak point

The server vulnerability, now called the ‘PrintNightmare vulnerability’, lives up to its nickname because it allows an external user to install programs, change data on a system, and create new accounts with system administrator rights.

The flaw allows the attacker to simply take over the domain account. According to reports, Microsoft itself admitted that “domain controllers are affected if the print spooler service is activated”.
