It is important to note that these patches and updates only tackle the remote code execution (RCE) part of the vulnerability.

The updates are cumulative and contain all previous fixes as well as protections for CVE-2021-1675.

Security updates have not yet been released for Windows 10 version 1607, Windows Server 2016, or Windows Server 2012, but they will also be released soon, according to Microsoft.

Older Windows versions (Windows 7 SP1, Windows 8.1 Server 2008 SP2, Windows Server 2008 R2 SP1, and Windows Server 2012 R2) will receive a security update that disallows users who are not administrators to install only signed print drivers to a print server.

So, many organizations were forced to keep the Print Spooler service enabled on some domain controllers, leaving them at risk to attacks using this vulnerability.ĭepending on the Windows version the patch will be offered as: If the spooler service is not running on at least one domain controller in each site, then Active Directory has no means to remove old queues that no longer exist. However, the installation of the Domain Controller (DC) role adds a thread to the spooler service that is responsible for removing stale print queue objects. Last week the Cybersecurity and Infrastructure Security Agency (CISA) urged administrators to disable the Windows Print Spooler service in domain controllers and systems that don't print. In the event it turned out to be a bit of both. The problem was exacerbated by confusion around whether PrintNightmare was a known, patched problem or an entirely new problem. PrintNightmare allows a standard user on a Windows network to execute arbitrary code on an affected machine, and to elevate their privileges as far as domain admin, by feeding a vulnerable machine a malicious printer driver. Yesterday, Microsoft issued a set of out-of-band patches that sets that aims to set that right by fixing the Windows Print Spooler Remote Code Execution vulnerability listed as CVE-2021-34527.įor Microsoft to publish an out-of-band patch a week before July's Patch Tuesday shows just how serious the problem is. After June's Patch Tuesday, researchers found that the patch did not work in every case, most notably on modern domain controllers. “The security updates released on and after Jcontain protections for CVE-2021-1675 and the additional remote code execution exploit in the Windows Print Spooler service known as ‘PrintNightmare’, documented in CVE-2021-34527.Last week we wrote about PrintNightmare, a vulnerability that was supposed to be patched but wasn't. “We recommend that you install these updates immediately,” says Microsoft.

The PrintNightmare vulnerability allows attackers to use remote code execution, so bad actors could potentially install programs, modify data, and create new accounts with full admin rights. It took Microsoft a couple of days to issue an alert about a 0-day affecting all supported versions of Windows. Microsoft says “security updates for these versions of Windows will be released soon.” Microsoft has not yet issued patches for Windows Server 2012, Windows Server 2016, and Windows 10 Version 1607, though. Microsoft has even taken the unusual step of issuing patches for Windows 7, which officially went out of support last year. Microsoft has issued out-of-band security updates to address the flaw, and has rated it as critical as attackers can remotely execute code with system-level privileges on affected machines.Īs the Print Spooler service runs by default on Windows, Microsoft has had to issue patches for Windows Server 2019, Windows Server 2012 R2, Windows Server 2008, Windows 8.1, Windows RT 8.1, and a variety of supported versions of Windows 10. The vulnerability, dubbed PrintNightmare, was revealed last week, after security researchers accidentally published proof-of-concept (PoC) exploit code. Microsoft has started rolling out an emergency Windows patch to address a critical flaw in the Windows Print Spooler service.
