US Critical Infrastructure Security Agency (CISA) adds CVE-2022-26925 Windows LSA flaw to its Known Exploited Vulnerabilities Catalog.
In May the US CISA removed the CVE-2022-26925 Windows LSA vulnerability from its Known Exploited Vulnerabilities Catalog due to Active Directory (AD) certificate authentication problems observed after the installation of Microsoft’s May 2022 Patch Tuesday security updates.
“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).” reads the advisory published by CISA. “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.”
According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.
Experts recommend also private organizations review the Catalog and address the vulnerabilities ..
