Microsoft Issues Emergency Patch to Address Critical PrintNightmare Vulnerability
Jul. 7, 2021While Microsoft prepares to refine the newly unveiledWindows 11 OSbefore its public release later this year, the company has today issued an emergency patch to address a critical vulnerability in current Windows versions. The Redmond giant has issued out-of-band security updates for various Windows versions, including Windows 7.
For the unaware, the vulnerability called “PrintNightmare” was recently revealed by a team of security researchers. It essentially allows attackers toremotelyexecute code within a system using a flaw in the Windows Print Spooler service. So, using this zero-day vulnerability, attackers can execute remote codes to install programs, create new accounts, and modify data with complete admin rights.
It happened when Sangfor researchers mistakenly shared a proof-of-concept (POC) code online a couple of days ago. They were planning to address various zero-day vulnerabilities in the Windows Print Spooler service at the annual Black Hat conference and thought that Microsoft had already patched the “PrintNightmare” vulnerability. Although before theydeletedthe POC from the web, it was already forked on Github.
