CISA Adds Two Known Exploited Vulnerabilities to Catalog

Dec 7, 2023

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2023-41265 Qlik Sense HTTP Tunneling Vulnerability CVE-2023-41266 Qlik Sense Path Traversal 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.

CISA Releases Joint Guide for Software Manufacturers: The Case for Memory Safe Roadmaps

Dec 6, 2023

Today, as part of the Secure by Design campaign, CISA published The Case for Memory Safe Roadmaps: Why Both C-Suite Executives and Technical Experts Need to Take Memory Safe Coding Seriously in collaboration with the following partners: United States National Security Agency United States Federal Bureau of Investigation Australian Signals Directorate’s Australian Cyber Security Centre Canadian Centre for Cyber Security United Kingdom National Cyber Security Centre New Zealand National Cyber Security Centre Computer Emergency Response Team New Zealand Malicious cyber actors routinely exploit memory safety vulnerabilities, which are common coding errors and the most prevalent type of disclosed software vulnerability. Preventing and responding to these vulnerabilities cost both software manufacturers and their customer organizations significant time and resources. The Case for Memory Safe Roadmaps details how software manufacturers can transition to memory safe programming languages (MSLs) to eliminate memory safety vulnerabilities. The guidance provides manufacturers steps for creating and publishing memory safe roadmaps that will show their customers how they are owning security outcomes, embracing radical transparency, and taking a top-down approach to developing secure products—key Secure by Design tenets. CISA and our partners urge C-suite and technical experts at software manufacturers to read this guidance and implement memory safe roadmaps to eliminate memory safety vulnerabilities from their product.

Exploitation of Unitronics PLCs used in Water and Wastewater Systems

Nov 28, 2023

CISA is responding to active exploitation of Unitronics programmable logic controllers (PLCs) used in the Water and Wastewater Systems (WWS) Sector. Cyber threat actors are targeting PLCs associated with WWS facilities, including an identified Unitronics PLC, at a U.S. water facility. In response, the affected municipality’s water authority immediately took the system offline and switched to manual operations—there is no known risk to the municipality’s drinking water or water supply. WWS Sector facilities use PLCs to control and monitor various stages and processes of water and wastewater treatment, including turning on and off pumps at a pump station to fill tanks and reservoirs, flow pacing chemicals to meet regulations, gathering compliance data for monthly regulation reports, and announcing critical alarms to operations.  Attempts to compromise WWS integrity via unauthorized access threaten the ability of WWS facilities to provide clean, potable water to, and effectively manage the wastewater of, their communities. The cyber threat actors likely accessed the affected device—a Unitronics Vision Series PLC with a Human Machine Interface (HMI)—by exploiting cybersecurity weaknesses, including poor password security and exposure to the internet. To secure WWS facilities against this threat, CISA urges organizations to: Change the Unitronics PLC default password—validate that the default password “1111” is not in use. Require multifactor authentication for all remote access to the OT network, including from the IT network and external networks. Disconnect the PLC from the open internet. If remote access is necessary, implement a Firewall/VPN in front of the PLC to control network access to the remote PLC. A VPN or gateway device can enable multifactor authentication for remote access even if the PLC does not support multifactor authentication. Unitronics also has a secure cellular based longhaul transport device that is secure to their cloud services. Back up the logic and configurations on any Unitronics PLCs to enable fast recovery. Become familiar with the process for factory resetting and deploying configurations to a device in the event of being hit by ransomware. If possible, utilize a TCP port that is different than the default port TCP 20256. Cyber actors are actively targeting TCP 20256 after identifying it through network probing as a port associated to Unitronics PLC. Once identified, they leverage scripts specific to PCOM/TCP to query and validate the system, allowing for further probing and connection. If available, use PCOM/TCP filters to parse out the packets. Update PLC/HMI to the latest version provided by Unitronics. CISA and WWS Sector partners have developed numerous tools and resources that water utilities can use to increase their cybersecurity.

CISA and UK NCSC Unveil Joint Guidelines for Secure AI System Development

Nov 26, 2023

Today, in a landmark collaboration, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the UK National Cyber Security Centre (NCSC) are proud to announce the release of the Guidelines for Secure AI System Development. Co-sealed by 23 domestic and international cybersecurity organizations, this publication marks a significant step in addressing the intersection of artificial intelligence (AI), cybersecurity, and critical infrastructure. The Guidelines, complementing the U.S. Voluntary Commitments on Ensuring Safe, Secure, and Trustworthy AI, provide essential recommendations for AI system development and emphasize the importance of adhering to Secure by Design principles. The approach prioritizes ownership of security outcomes for customers, embraces radical transparency and accountability, and establishes organizational structures where secure design is a top priority. The Guidelines apply to all types of AI systems, not just frontier models. We provide suggestions and mitigations that will help data scientists, developers, managers, decision-makers, and risk owners make informed decisions about the secure design, model development, system development, deployment, and operation of their machine learning AI systems. This document is aimed primarily at providers of AI systems, whether based on models hosted by an organization or making use of external application programming interfaces. However, we urge all stakeholders—including data scientists, developers, managers, decision-makers, and risk owners make—to read this guidance to help them make informed decisions about the design, deployment, and operation of their machine learning AI systems. CISA invites stakeholders, partners, and the public to explore the Guidelines for Secure AI System Development as well as our recently published Roadmap for AI to learn more about our strategic vision for AI technology and cybersecurity. To access learn more, visit CISA.gov/AI.
