(вЂњZero-dayвЂќ is the jargon for a previously unknown and unpatched security hole, because it means that the Good Guys were zero days ahead when the Bad Guys first got to hear about it.) In the jargon of the cybersecurity industry, the researchers had unwittingly dropped an 0-day.

Their bug was not CVE-2021-1675 at all it was CVE-2021-34527, although no one knew that at the time, because that additional bug number was only issued later on.Д®ven worse, this new RCE hole wasnвЂ™t blocked by MicrosoftвЂ™s Patch Tuesday update, making the published code into a publicly available, fully functional, break-and-enter exploit. With hindsight, which is a wonderful thing indeed, we can compute that chance precisely: 100 percent.

вЂњ WhatвЂ™s the chance,вЂќ we guess they asked themselves, вЂњ that two different RCE bugs, working in what sounds like exactly the same way, would be found at exactly the same time in exactly the same Windows component, namely the Print Spooler?вЂќ

Later in the month, however, Microsoft admitted that CVE-2021-1675 could also be used for RCE, and updated its public advisory to say so.Д®ven though that meant the bug was more serious in theory, no one worried too much in practice.ДЄfter all, a patch was already available, and anyone who had installed the patch to close the EoP hole was, ipso facto, protected against the newly announced RCE hole as well.ДЄt this point, the researchers then apparently assumed that their bug was not original, as they had first thought.Д«ecause it had already been patched, they assumed that it would therefore not be untimely to publish their existing proof-of-concept exploit code to explain how the vulnerability worked. Given that the Chinese researchersвЂ™ bug was apparently different, they hadnвЂ™t disclosed it yet. Theirs sounded very similar, except that it was an RCE bug, short for remote code execution, meaning that it could be used for breaking in, not merely for elevating privilege.

In the meantime, Chinese researchers preparing a paper for the 2021 Black Hat conference were working on their own bug in the Windows Print Spooler. Originally, the bug was reported as an elevation of privilege (EoP) vulnerability, meaning that although attackers already on your computer could exploit the bug to promote themselves from a regular user to a system account, they couldnвЂ™t use it to break into your computer in the first place. PrintNightmare, the zero-day hole in Windows вЂ“ hereвЂ™s what to doД«riefly put, Microsoft published a Windows Print Spooler patch for a bug dubbed CVE-2021-1675, as part of the June 2021 Patch Tuesday update that came out on. ICYMI, PrintNightmare is an aptly named bug that became a public danger for the unfortunate reason that a team of security researchers jumped to an incorrect conclusion: HereвЂ™s the bad news: early reports suggest that the patch doesnвЂ™t protect against all aspects of the PrintNightmare bug, and that it may be possible to bypass the patch entirely, depending on the version of Windows involved and the Print Spooler configuration on the targeted computer. (This month, thatвЂ™s, which is still almost a week away.)

In Windows update parlance, OOB refers to patches that are deemed so important that they canвЂ™t wait until the next official Patch Tuesday, which is always the second Tuesday in each calendar month. OOB is a jargon term that refers to communications that are kept separate from the usual channel you use, notably for safety reasons in case the main channel should fail or need overriding in an emergency. The patch is what Redmond refers to as an OOB Security Update, where OOB is short for out-of-band. HereвЂ™s the good news: Microsoft has released an emergency patch for the infamous PrintNightmare bug that was revealed in the Windows Print Spooler just over a week ago.
