An attacker could then install programs view, change, or delete data or create new accounts with full user rights. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. All we officially know at this time is that “A remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. There is yet another CVE ( CVE-2021-36958) for which we have no patch, and the only workaround is to disable the print spooler.

Instead they use a generic preloaded driver named ‘Microsoft enhanced Point and Print.’” However, some network admins have indicated that the V4 drivers aren’t the solution either.īut even if you could get the August updates installed in your network, that doesn’t mean you are fully protected from print spooler vulnerabilities. When clients connect to a printer on a server using a V4 driver, they do not download any driver. As Fontanez wrote, “V4 drivers use a model-specific driver on the print server side. If your printer vendor doesn’t have a V4 version of the printer driver, ensure that you reach out to your vendor - especially if they are under active leases - and demand that they come out with a revised driver. You may have to deploy the drivers on a test virtual machine in order to determine exactly what printer driver you have. In the case of Hewlett Packard printers, PCL 6 denotes V3, whereas PCL-6 (note the hyphen) denotes V4.
But therein lies a problem - it’s often extremely hard to determine if drivers are V3 or V4. As he points out, one of the solutions is to ensure you have V4 printer drivers deployed in your network. Fontanez has blogged here and here with some great discussion of what is going on. are already installed and it is already under investigation, we do not have an estimated time of fix yet, but we are working on it.” But while the company may be privately acknowledging that there is a problem with printing, it isn’t showcasing it on the Windows health release dashboard.Īnthony J. Microsoft has privately acknowledged in a support case that “the admin/install prompt for already-installed drivers and already-installed printers is unexpected behavior.” It went on to say, “We have received new reports that this is also affecting customers where the drivers/printers, etc. Getting to the heart of the print problem Reg add "HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Printers\PointAndPrint" /v RestrictDriverInstallationToAdministrators /t REG_DWORD /d 0 /fīut doing so exposes you to publicly known vulnerabilities, and neither Microsoft nor I recommend it. Those who do want to make the registry change can open a Command Prompt window with elevated permissions and enter the following:

Given that firms are likely to keep users without administrator rights to limit lateral movement (and quite frankly because Microsoft has told us over the years that running with administrator rights was a bad thing), we’re now having to decide to give users local administrator rights, make a registry key adjustment that weakens security, or roll back the patch until Microsoft figures out what went wrong. We’re also seeing that when the patch is on the workstation and not on the server, it’s triggering a reinstallation of the print drivers.
More precisely, when the print server is on a Server 2016 server, the printers are pushed out via Group Policy, and the printer driver from the vendor is a V3 driver, it is triggering the reinstallation of print drivers. However, what we’re seeing over on the list is that anyone with a V3 style of print driver is having their users be prompted to reinstall drivers or install new drivers.

Update existing printer drivers using drivers from remote computer or server”.Install new printers using drivers on a remote computer or server.As noted in KB5005652, “by default, non-administrator users will no longer be able to do the following using Point and Print without an elevation of privilege to administrator: Microsoft made a change in how Group Policy printers are handled when it changed the default Point and Print behavior to address “PrintNightmare” vulnerabilities affecting the Windows Print Spooler service. But over the last several months you’ve made it near impossible to stay fully patched and keep printing.Ĭase in point: the August security updates.

We aren’t all paperless out here in the business world - many of us still need to click the Print button inside our business applications and print things out on an actual sheet of paper, or send something to a PDF printer.
