Microsoft finally fixes PrintNightmare vulnerability with KB5005031 and KB5005033 updates


To help address the ongoing problems with the so-called PrintNightmare vulnerability (CVE-2021-34527), Microsoft has announced a change to the default behavior of the Point and Print feature in Windows.
The change has been delivered via the KB5005033 and KB5005031 update and means that in order to install printer drivers, users will have to have administrative privileges. This mitigates against the Windows Print Spooler vulnerability that allowed any user to install drivers via Point and Print, a fact that could be exploited to install a malicious drivers to allow for remote code execution and SYSTEM privileges.

Microsoft has released a series of out of-band security patches for the PrintNightmare bug that was recently exposed. The remote code execution vulnerability exits in the Windows Print Spooler; it affects all versions of Windows, and the company is even offering patches for the unsupported Windows 7.
Previously, Microsoft had only been able to suggest workarounds to mitigate against the security problems, so it was left to 0patch to help out with a free bug-fix. But now patches are available for this serious security issue (CVE-2021-34527) that leaves systems at risk of attack.
