A security flaw in the Windows Print Spooler component that was patched by Microsoft in February is being actively exploited in the wild, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has warned.

To that end, the agency has added the shortcoming to its Known Exploited Vulnerabilities Catalog, requiring Federal Civilian Executive Branch (FCEB) agencies to address the issues by May 10, 2022.

Tracked as CVE-2022-22718 (CVSS score: 7.8), the security vulnerability is one among the four privilege escalation flaws in the Print Spooler that Microsoft resolved as part of its Patch Tuesday updates on February 8, 2022.

It’s worth noting that the Redmond-based tech giant has remediated a number of Print Spooler flaws since the critical PrintNightmare remote code execution vulnerability came to light last year, including 15 elevation of privilege vulnerabilities in April 2022.

Specifics about the nature of the attacks and the identity of the threat actors that may be exploiting the Print Spooler defect remain unknown, partly in an attempt to prevent further exploitation by hacking crews. Microsoft, for its part, assigned it an “exploitation more likely” tag back when the fixes were rolled out two months ago.
