CVE-2021-34481 is a vulnerability in the Windows Print Spooler service caused by improper privileged file operations. The flaw affects the Print Spooler component and can be abused to achieve arbitrary code execution in the context of NT AUTHORITY\SYSTEM. Public reporting around the vulnerability associated it with the broader PrintNightmare class of Print Spooler issues and noted exploitation paths involving installation of vulnerable print drivers through Point and Print-related behavior. Although some reporting initially described the issue as local privilege escalation, Microsoft classified it as remote code execution and later released security updates to address it.
