| Impact | CVSS 7.5, EPSS 28.3%. LSASS is critical infrastructure on every Windows server. A DoS against domain controllers' LSASS would prevent all domain authentication across the enterprise. No authentication required to trigger. |
| Exploit ScenarioDerived | An attacker sends crafted requests to a domain controller that exhaust LSASS resources. Domain authentication fails across the enterprise: users cannot log in, services cannot authenticate, and Kerberos ticket validation stops. The organization is effectively offline until the domain controller is restarted. |

Alert meAnalysisAIv1 – Mar 14, 2026
Windows Local Security Authority Subsystem Service (LSASS) contains an uncontrolled resource consumption vulnerability that allows unauthenticated remote attackers to cause a denial of service. Crashing or degrading LSASS disrupts all authentication and authorization on the affected Windows server, effectively taking the system offline.
Earlier versions of this analysis (1)
Remote DoS against Windows LSASS service disrupts all authentication on the targeted server.
RemediationAI
Apply the Microsoft security update. Implement network segmentation to restrict access to LSASS-exposed ports on domain controllers. Monitor LSASS resource usage for anomalies. Ensure multiple domain controllers for redundancy.

Technical ContextAI · show details
LSASS handles all authentication and authorization decisions on Windows systems. An uncontrolled resource consumption flaw allows a remote attacker to exhaust LSASS resources, causing the service to become unresponsive. When LSASS fails, the system cannot process logons, validate Kerberos tickets, or enforce security policies, effectively denying all access to the machine.

Lifecycle Timeline
3DescriptionCVE.org
Uncontrolled resource consumption in Windows Local Security Authority Subsystem Service (LSASS) allows an unauthorized attacker to deny service over a network.
Executive ViewAI
CVE-2025-32724 is a high-severity denial-of-service vulnerability in Windows LSASS that allows remote attackers to crash authentication services on affected servers without credentials, rendering systems unable to authenticate users or authorize access. This directly impacts operational continuity for any organization relying on affected Windows servers for network services, directory services, or user access.
Apply vendor patch. Interim mitigation: Restrict network access to affected Windows systems using firewall rules and network segmentation to block unauthenticated remote connections; implement rate-limiting on authentication services; monitor LSASS process resource consumption for anomalies indicative of exploitation attempts.
