PrintNightmare - Security printing challenges in 2021

Posted on 16/09/2021

Over the past couple of months, there has been an increasing amount of discussion surrounding a privilege escalation bug found in the print spooler service on several Windows platforms.

Named PrintNightmare, the issue was believed to allow users with existing authentication to escalate their privileges, allowing them to override admin rights, furthermore, exposing the vulnerabilities of the platform to remote code execution.

The issue first came to the surface in early June 2021 when Microsoft patched the vulnerability in the print spooler (CVE-2021-1675). However, later in the month things seemed to escalate further, with the confirmation that the patch had not been successful in remedying the issue.

Despite the best efforts of Microsoft, it is thought that PrintNightmare is still an issue for Windows 10 to this day.

Microsoft explains the issue, which is labelled CVE-2021-36958:

A remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

The workaround for this vulnerability is stopping and disabling the Print Spooler service.

While this is something Windows are working hard to resolve, it is uncertain when they will regain control of this issue.
