CISA has added five new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.
· Microsoft Windows DWM Core Library Use-After-Free Vulnerability
· Microsoft Windows Common Log File System (CLFS) Driver Use-After-Free Vulnerability
· Microsoft Windows Common Log File System (CLFS) Driver Heap-Based Buffer Overflow Vulnerability
· Microsoft Windows Scripting Engine Type Confusion Vulnerability
- Microsoft Windows Ancillary Function Driver for WinSock Use-After-Free 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.
