CISA ADDS ONE KNOWN EXPLOITED VULNERABILITY TO CATALOG

Release Date
March 04, 2024


CISA has added one new vulnerability to its Known Exploited Vulnerabilities
Catalog, based on evidence of active exploitation.

 * CVE-2024-21338 Microsoft Windows Kernel Exposed IOCTL with Insufficient
   Access Control Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber
actors and pose significant risks to the federal enterprise.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of
Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities
Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs)
that carry significant risk to the federal enterprise. BOD 22-01 requires
Federal Civilian Executive Branch (FCEB) agencies to remediate identified
vulnerabilities by the due date to protect FCEB networks against active threats.
See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all
organizations to reduce their exposure to cyberattacks by prioritizing timely
remediation of Catalog vulnerabilities as part of their vulnerability management
practice. CISA will continue to add vulnerabilities to the catalog that meet
the specified criteria.
