CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.
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.
Today, CISA—on behalf of the collective group of industry and government partners that comprise the Joint Cyber Defense Collaborative (JCDC)—released JCDC’s 2024 Priorities. Similar to the 2023 JCDC Planning Agenda, JCDC’s 2024 Priorities will help focus the collective group on developing high-impact and collaborative solutions to the most pressing cybersecurity challenges.
Resulting from the trusted partnerships the collaborative has fostered, the focused goals of the 2024 priorities are to:
CISA encourages organizations to review JCDC’s 2024 Priorities and the related blog post by CISA Associate Director Clayton Romans. Visit CISA.gov/JCDC for more information on the work the collaborative is doing to secure cyberspace.

The following federal agencies and international organizations are additional co-authors on the joint advisory and guidance:
Volt Typhoon actors are seeking to pre-position themselves—using living off the land (LOTL) techniques—on IT networks for disruptive or destructive cyber activity against U.S. critical infrastructure in the event of a major crisis or conflict with the United States. The advisory provides actionable information from U.S. incident response activity that can help all organizations:
To supplement the advisory, the Joint Guidance provides threat detection information and mitigations applicable to LOTL activity, regardless of threat actor. Additionally, CISA has published Secure by Design Alert: Security Design Improvements for SOHO Device Manufacturers, which provides technology manufactures guidance on protecting their products from Volt Typhoon compromises.
CISA and its partners strongly urge critical infrastructure organizations and technology manufacturers to read the joint advisory and guidance to defend against this threat.

Today, CISA and the Federal Bureau of Investigation (FBI) published guidance on Security Design Improvements for SOHO Device Manufacturers as a part of the new Secure by Design (SbD) Alert series that focuses on how manufacturers should shift the burden of security away from customers by integrating security into product design and development.
This third publication in CISA’s SbD Alert series examines how manufacturers can eliminate the path threat actors—particularly the People’s Republic of China (PRC)-sponsored Volt Typhoon group—are taking to compromise small office/home office (SOHO) routers. Specifically, CISA and FBI urge manufacturers to:
CISA and FBI also urge manufacturers to protect against Volt Typhoon activity and other cyber threats by disclosing vulnerabilities via the Common Vulnerabilities and Exposures (CVE) program as well as by supplying accurate Common Weakness Enumeration (CWE) classification for these vulnerabilities. The Alert also urges manufacturers to implement incentive structures that prioritize security during product design and development.
CISA and FBI urge SOHO device manufacturers to read and implement Security Design Improvements for SOHO Device Manufacturers, which aligns to principles one through three of the joint guidance, Shifting the Balance of Cybersecurity Risk: Principles and Approaches for Secure by Design Software:
By implementing these principles in their design, development, and delivery processes, manufactures can prevent exploitation of SOHO routers. To learn more, visit Secure by Design.
