Set of patchesĭepending on the Windows version the patch will be offered as: 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. 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. Serious problemįor Microsoft to publish an out-of-band patch a week before July’s Patch Tuesday shows just how serious the problem is. 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.

Last week we wrote about PrintNightmare, a vulnerability that was supposed to be patched but wasn’t.
