CVE-2024-30083 Overview
CVE-2024-30083 is a denial of service vulnerability in the Windows Standards-Based Storage Management Service. The flaw affects multiple Windows Server versions and can be exploited remotely over the network without authentication or user interaction. A successful attack disrupts the availability of the storage management service, which impacts storage provisioning and monitoring workflows dependent on it. Microsoft classifies the issue as high severity based on the availability impact. The vulnerability is tracked under [CWE-121] (Stack-based Buffer Overflow), pointing to memory corruption on the stack as the underlying weakness.
Critical Impact
Unauthenticated remote attackers can crash the Windows Standards-Based Storage Management Service on affected Windows Server systems, disrupting storage management operations.
Affected Products

Technical Details for CVE-2024-30083
Vulnerability Analysis
The Windows Standards-Based Storage Management Service implements SMI-S (Storage Management Initiative Specification) based management for storage arrays and provides a WMI interface used by storage administration tools. CVE-2024-30083 exists in this service and is categorized as a stack-based buffer overflow under [CWE-121]. An attacker who can reach the service over the network can send crafted input that triggers the overflow, causing the service process to terminate abnormally. The result is a denial of service condition affecting storage management functionality on the host.
Because the vulnerability requires no privileges and no user interaction, exploitation depends only on network reachability to the exposed service endpoint. The EPSS value of 2.504% (82.7 percentile) places this CVE in the upper range of predicted exploitation likelihood relative to other CVEs.
Root Cause
The root cause is improper bounds checking within the Standards-Based Storage Management Service when processing attacker-controlled input on a stack buffer. Writing beyond the buffer boundary corrupts adjacent stack data, including saved return addresses and frame metadata, which causes the service to crash. Microsoft has not published the specific function or parsing routine responsible.
Attack Vector
The attack vector is network based. An unauthenticated remote attacker sends crafted requests to the Standards-Based Storage Management Service on a targeted Windows Server. If the service is enabled and reachable, the malformed input triggers the stack overflow and terminates the service. The vulnerability does not permit code execution or data disclosure based on the CVSS impact metrics, which show no confidentiality or integrity impact.
No public proof-of-concept or exploit code has been observed, and CISA has not added the CVE to the Known Exploited Vulnerabilities catalog. Refer to the Microsoft Security Update CVE-2024-30083 advisory for vendor-provided technical details.
Detection Methods for CVE-2024-30083
Indicators of Compromise
- Unexpected termination or repeated restarts of the Standards-Based Storage Management Service (smphost / SMPHost) on Windows Server hosts.
- Windows Service Control Manager events (Event ID 7031, 7034) referencing the storage management service crashing unexpectedly.
- Windows Error Reporting or application crash dumps generated for the storage management service process without a corresponding administrative action.
Detection Strategies
- Monitor Windows Event Logs for service crash and restart events tied to the Standards-Based Storage Management Service and alert on repeated failures within short intervals.
- Correlate inbound network traffic to WMI and storage management endpoints with service failure events to identify probable exploitation attempts.
- Inventory hosts running the SMPHost service and confirm patch status against the Microsoft advisory.
Monitoring Recommendations
- Enable auditing for service state changes on Windows Servers where the Standards-Based Storage Management Service is running.
- Forward Windows Security, System, and Application logs to a centralized log platform for correlation and alerting.
- Track anomalous WMI activity and network connections targeting storage management interfaces.
How to Mitigate CVE-2024-30083
Immediate Actions Required
- Apply the Microsoft security update referenced in the Microsoft Security Update CVE-2024-30083 advisory to all affected Windows Server systems.
- Identify systems where the Standards-Based Storage Management Service is enabled and prioritize patching those first.
- Restrict network access to storage management interfaces to trusted administrative networks only.
Patch Information
Microsoft addressed CVE-2024-30083 in the June 2024 Patch Tuesday cycle. Updates are available for Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019, and Windows Server 2022. Consult the Microsoft Security Update CVE-2024-30083 advisory for the specific KB articles matching each supported Windows Server release.
Workarounds
- Disable the Standards-Based Storage Management Service (SMPHost) on servers that do not require SMI-S based storage management.
- Block inbound network access to WMI and storage management endpoints from untrusted networks using host firewall rules or network segmentation.
- Limit administrative access to storage management functions to a small set of hardened management hosts.
# Configuration example: disable the service if not required
sc.exe config SMPHost start= disabled
sc.exe stop SMPHost
# Verify status
sc.exe query SMPHost
