CISA Current Activity (RSS)

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

— CVE-2025-61932 Motex LANSCOPE Endpoint Manager Improper Verification of Source of a Communication Channel Vulnerability

This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise. 

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV 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 KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

‌Microsoft Releases Out-of-Band Security Update to Mitigate Windows Server Update Service Vulnerability, CVE-2025-59287
CISA Current Activity (RSS)

Microsoft released an update to address a critical remote code execution vulnerability impacting Windows Server Update Service (WSUS) in Windows Server (2012, 2016, 2019, 2022, and 2025), CVE-2025-59287, that a prior update did not fully mitigate. 

CISA strongly urges organizations to implement Microsoft’s updated Windows Server Update Service (WSUS) Remote Code Execution Vulnerability guidance, 1 or risk an unauthenticated actor achieving remote code execution with system privileges. Immediate actions for organizations with affected products are:

— Identify servers that are currently configured to be vulnerable to exploitation (i.e., affected servers with WSUS Server Role enabled and ports open to 8530/8531) for priority mitigation.
— Apply the out-of-band security update released on October 23, 2025, to all servers identified in Step 1. Reboot WSUS server(s) after installation to complete mitigation. If organizations are unable to apply the update immediately, system administrators should disable the WSUS Server Role and/or block inbound traffic to ports 8530/8531, the default listeners for WSUS, at the host firewall. Of note, do not undo either of these workarounds until after your organization has installed the update.
— Apply updates to remaining Windows servers. Reboot servers after installation to complete mitigation.

CISA added CVE-2025-59287 to its Known Exploited Vulnerabilities (KEV) Catalog on October 24, 2025.

‌New Guidance Released on Microsoft Exchange Server Security Best Practices
CISA Current Activity (RSS)

Today, CISA, in partnership with the National Security Agency and international cybersecurity partners, released Microsoft Exchange Server Security Best Practices, a guide to help network defenders harden on-premises Exchange servers against exploitation by malicious actors.

Threat activity targeting Exchange continues to persist, and organizations with unprotected or misconfigured Exchange servers remain at high risk of compromise. 

Best practices in this guide focus on hardening user authentication and access, ensuring strong network encryption, and minimizing application attack surfaces. CISA recommends organizations also decommission any remaining end-of-life on-premises or hybrid Exchange servers after transitioning to Microsoft 365, as retaining the “last Exchange server” can expose organizations to ongoing exploitation activity. 

CISA recommends organizations implement Microsoft Exchange Server Best Practices and take steps to decommission end-of-life on-premises Exchange servers in hybrid environments to significantly reduce their risk from cyber threats.
