UPDATE HISTORY November 07, 2023: Initial Publication

CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2023- 22518 Atlassian Confluence Data Center and Server Improper Authorization 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. 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.

Today, the Federal Emergency Management Agency (FEMA) and the Cybersecurity and Infrastructure Security Agency (CISA) released the joint guide Planning Considerations for Cyber Incidents: Guidance for Emergency Managers to provide state, local, tribal, and territorial (SLTT) emergency managers with foundational knowledge of cyber incidents to increase cyber preparedness efforts in their jurisdictions. Emergency managers should be able to understand and prepare for the potential impacts of cyber incidents on their communities and emergency operations. FEMA and CISA encourage emergency managers to review this guide for recommendations on how to plan for and respond to cyber incidents. For continued updates on efforts related to the guide, including webinars, please visit FEMA’s webpage.

Today, CISA, in response to active, targeted exploitation, released guidance for addressing Citrix NetScaler ADC and Gateway vulnerability CVE-2023-4966. The vulnerability, also known as Citrix Bleed, could allow a cyber actor to take control of an affected system. CISA recommends organizations patch unmitigated appliances, hunt for any malicious activity, and report any positive findings to CISA. Review CISA’s guidance for more information.
