Security News > 2021 > July > Actively exploited PrintNightmare zero-day gets unofficial patch

Free micropatches addressing the actively exploited PrintNightmare zero-day vulnerability in the Windows Print Spooler service are now available through the 0patch platform.

The buggy code behind this remote code execution bug is present in all versions of Windows, with Microsoft still investigating if the vulnerability can be exploited exploitable on all of them.

Even though no security updates are available to address the PrintNightmare security flaw at the moment, Microsoft has shared mitigation measures to block attackers from compromising vulnerable systems and is working on a fix.

The company's advice takes into consideration the fact that this service is enabled by default on most Windows clients and server platforms, drastically increasing the risk of future attacks targeting vulnerable systems.

Until official security updates are available, applying the 0patch micropatches or implementing the mitigations provided by Microsoft should block attackers from breaching your network using PrintNightmare exploits.

Our patches will be free until Microsoft has issued an official fix.
