CISA Temporarily Removes CVE-2022-26925 from Known Exploited Vulnerability Catalog

4 days 13 hours ago
Original release date: May 13, 2022

CISA is temporarily removing CVE-2022-26925 from its Known Exploited Vulnerability Catalog due to a risk of authentication failures when the May 10, 2022 Microsoft rollup update is applied to domain controllers. After installing May 10, 2022 rollup update on domain controllers, organizations might experience authentication failures on the server or client for services, such as Network Policy Server (NPS), Routing and Remote access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP). Microsoft notified CISA of this issue, which is related to how the mapping of certificates to machine accounts is being handled by the domain controller.

For more information see the Microsoft Knowledge Base article, KB5014754—Certificate-based authentication changes on Windows domain controllers: Key Distribution Center registry key.

Note: installation of updates released May 10, 2022, on client Windows devices and non-domain controller Windows Servers will not cause this issue and is still strongly encouraged. This issue only affects May 10, 2022 updates installed on servers used as domain controllers. Organizations should continue to apply updates to client Windows devices and non-domain controller Windows Servers.

U.S. Government Attributes Cyberattacks on SATCOM Networks to Russian State-Sponsored Malicious Cyber Actors

1 week 1 day ago
Original release date: May 10, 2022

CISA and the Federal Bureau of Investigation (FBI) have updated the joint cybersecurity advisory, Strengthening Cybersecurity of SATCOM Network Providers and Customers, originally released March 17, 2022, with U.S. government attribution to Russian state-sponsored malicious cyber actors. The United States assesses Russia launched cyberattacks in late February against commercial satellite communications networks to disrupt Ukrainian command and control during the Russia invasion, and those actions had spillover impacts into other European countries.

CISA is working with both international and JCDC partners to strengthen our collective cybersecurity resilience—especially in the critical infrastructure that governments and citizens rely on—and to protect against and respond to malicious cyber activity.  We continue to urge public and private sector partners to review and implement the guidance contained in U.S. government cybersecurity advisories, including Strengthening Cybersecurity of SATCOM Network Providers and Customers, the January 2022 cybersecurity advisory on Protecting VSAT Communications, and the April 2022 cybersecurity advisory on Russian State-Sponsored and Criminal Threats to Critical Infrastructure. CISA also recommends partners review the CISA Shields Up, Shields Up Technical Guidance, and Russia webpages to stay current on the preventive measures that can help guard against Russian cyber threats and tactics.
