CISA released two Industrial Control Systems (ICS) advisories on February 1, 2024. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.
CISA encourages users and administrators to review the newly released ICS advisories for technical details and mitigations.
Moby and the Open Container Initiative (OCI) have released updates for multiple vulnerabilities (CVE-2024-23651, CVE-2024-23652, CVE-2024-23653, CVE-2024-21626) affecting Docker-related components, including Moby BuildKit and OCI runc. A cyber threat actor could exploit these vulnerabilities to take control of an affected system.
CISA encourages users and administrators to review the advisories from Moby BuildKit (CVE-2024-23651, CVE-2024-23652, CVE-2024-23653) and OCI runc (CVE-2024-21626), as well as the Snyk blog post about these vulnerabilities and apply the necessary updates.
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 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.
Note: CISA will update this Alert with more information as it becomes available.
Updated Jan. 31, 2024:
CISA urges organizations to follow the updated guidance—including software updates—that Ivanti has published to their KB article, which includes:
Additionally, CISA has issued a Supplemental Direction to its Emergency Directive on Ivanti Vulnerabilities. Although the Supplemental Direction and Emergency Directive are only for FCEB agencies, CISA strongly encourages all organizations to review the guidance and implement it as applicable.
End of Jan. 31 update
CISA is releasing this alert to provide cyber defenders with new mitigations to defend against threat actors exploiting Ivanti Connect Secure and Policy Secure Gateways vulnerabilities in Ivanti devices (CVE-2023-46805 and CVE-2024-21887).
Threat actors are continuing to leverage vulnerabilities in Ivanti Connect Secure and Policy Secure Gateways to capture credentials and/or drop webshells that enable further compromise of enterprise networks. Some threat actors have recently developed workarounds to current mitigations and detection methods and have been able to exploit weaknesses, move laterally, and escalate privileges without detection. CISA is aware of instances in which sophisticated threat actors have subverted the external integrity checker tool (ICT), further minimizing traces of their intrusion.
If an organization has been running Ivanti Connect Secure (9.x and 22.x) and Policy Secure gateways over the last several weeks and/or continues to run these products, CISA recommends continuous threat hunting on any systems connected to—or recently connected to—the Ivanti device. Additionally, organizations should monitor authentication, account usage, and identity management services that could be exposed and isolate the system(s) from any enterprise resources as much as possible.
After applying patches, when these become available, CISA recommends that organizations continue to hunt their network in order to detect any compromise that may have occurred before patches were implemented.
This guidance supplements CISA’s previous guidance for mitigation and detection, which remains applicable. For previous guidance, see CISA Issues Emergency Directive on Ivanti Vulnerabilities and Ivanti Releases Security Update for Connect Secure and Policy Secure Gateways.
CISA released eight Industrial Control Systems (ICS) advisories on January 30, 2024. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.

Juniper Networks released a security bulletin to address multiple vulnerabilities for J-Web in Junos OS SRX Series and EX Series. A cyber threat actor could exploit one of these vulnerabilities to take control of an affected system.
CISA encourages users and administrators to review the Juniper Bulletin JSA76390 and apply the necessary updates.
Today, CISA published Guidance on Assembling a Group of Products created by the Software Bill of Materials (SBOM) Tooling & Implementation Working Group, one of the five SBOM community-driven workstreams facilitated by CISA. CISA’s community-driven working groups publish documents and reports to advance and refine SBOM and ultimately promote adoption. Specifically, software producers often need to assemble and test products together before releasing them to customers. These products may contain components that experience version changes over time, therefore creating a need to be tracked. This document serves as a guide for creating the build for SBOM assembled products.
For more information on all things SBOM, please visit CISA’s Software Bill of Materials website.
