CISA has added five new vulnerabilities to its Catalog of Known Exploited Vulnerabilities (KEV), based on evidence of active exploitation.
- CVE-2017-7921 Multiple Hikvision Products Improper Authentication Vulnerability
- CVE-2021-22681 Insufficient Protected Credentials Vulnerability in Multiple Rockwell Products
- CVE-2021-30952 Integer overflow or loopback vulnerability in multiple Apple products
- CVE-2023-41974 Apple iOS and iPadOS Use-After-Release Vulnerability
- CVE-2023-43000 Use-after-release vulnerability of multiple Apple products
These types of vulnerabilities are frequent attack vectors for malicious cyber actors and present significant risks to the federal enterprise.
Binding Operational Directive (BOD) 22-01: Reducing Significant Risk from Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that pose significant risk to the Federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities in a timely manner to protect FCEB networks from active threats. See BOD Information Sheet 22-01 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 the rapid remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
