CISA Adds Two Known Exploited Vulnerabilities to Catalog, Removes Five KEVs

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation:

• CVE-2023-42793 JetBrains TeamCity Authentication Bypass Vulnerability
• CVE-2023-28229 Microsoft Windows CNG Key Isolation Service Privilege Escalation Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Note: To view other newly added vulnerabilities in the catalog, click on the arrow in the "Date Added to Catalog" column—which will sort by descending dates.

CISA is continually collaborating with partners across government and the private sector. As a result of this collaboration, CISA has concluded that there is insufficient evidence to keep the following five CVEs in the catalog and has removed them:

• CVE-2022-31459 Owl Labs Meeting Owl Inadequate Encryption Strength Vulnerability
• CVE-2022-31460 Meeting Owl Pro and Whiteboard Owl Hard-Coded Credentials Vulnerability
• CVE-2022-31461 Owl Labs Meeting Owl Missing Authentication for Critical Function Vulnerability
• CVE-2022-31462 Owl Labs Meeting Owl Use of Hard-coded Credentials Vulnerability
• CVE-2022-31463 Owl Labs Meeting Owl Improper Authentication Vulnerability

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.
