Windows NTFS Information Disclosure (CVE-2025-24984)

Historical catalog analysis: CISA added this entry on March 11, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2025-24984 is an information disclosure vulnerability within the Microsoft Windows New Technology File System (NTFS). The flaw involves the insertion of sensitive information into log files (CWE-532), which could allow an unauthorized attacker to read portions of heap memory.

Exposure and applicability

This vulnerability affects systems utilizing the Windows NTFS file system. Based on the source data, the attack vector is classified as physical; therefore, exposure is highest for assets where an attacker has direct physical access to the hardware or storage media. Organizations managing large fleets of laptops, edge devices, or unsecured workstations should prioritize these assets over isolated server environments.

Remediation priorities

Our analysis suggests prioritizing remediation based on the physical accessibility of the affected systems. We recommend the following actions:

1. Apply Vendor Mitigations: Deploy updates and mitigations as specified in Microsoft’s official instructions to address the underlying heap memory disclosure flaw.
2. Physical Access Control: For high-value assets, restrict physical access to hardware to reduce the likelihood of an attacker initiating the required physical attack vector.
3. Cloud Service Review: For organizations utilizing cloud environments, review and apply applicable BOD 22-01 guidance where relevant to their specific service model.
4. Asset Decommissioning: In scenarios where mitigations are unavailable or cannot be applied to legacy systems, consider discontinuing the use of the affected product version.

How to validate remediation

Verification must go beyond a simple version check or patch confirmation. To ensure exposure is reduced, vulnerability management teams should:
* Verify Patch Application: Confirm that the specific security update addressing CVE-2025-24984 is successfully installed across all targeted endpoints.
* Audit Physical Security: Validate that physical access controls (e.g., locked server racks, disabled boot-from-USB settings) are active on high-risk assets to mitigate the primary attack vector.
* Configuration Audit: Ensure that system configurations align with vendor-recommended hardening guides for NTFS and log management.

Limits and open questions

While patching addresses the software flaw, residual risk remains if physical security is compromised. It is currently unknown whether this vulnerability has been leveraged in active ransomware campaigns. Furthermore, while the source identifies the attack vector as physical, the specific mechanism by which an attacker triggers the heap memory disclosure into log files is not detailed; defenders should monitor for unusual log file growth or unauthorized access to system logs.
