How the CVE Works:
CVE-2025-24984 is a critical vulnerability in Windows NTFS (New Technology File System) that allows sensitive information to be inadvertently written into log files. This occurs due to improper handling of file metadata during certain operations, such as file creation, modification, or deletion. An attacker with physical access to the system can exploit this vulnerability by analyzing these log files to extract sensitive data, such as encryption keys, user credentials, or other confidential information. The vulnerability stems from a lack of proper sanitization of metadata before it is logged, making it possible for attackers to reconstruct sensitive data from fragmented log entries.
DailyCVE Form:
Platform: Windows NTFS
Version: All versions up to patch
Vulnerability: Information Disclosure
Severity: Critical
Date: 03/11/2025
What Undercode Say:
Exploitation:
- Physical Access Required: An attacker must have physical access to the system to read the log files stored on the disk.
- Log Analysis: Use tools like
strings,grep, or custom scripts to parse NTFS log files for sensitive data fragments. - Data Reconstruction: Combine fragmented metadata from logs to reconstruct sensitive information.
Protection:
- Apply Patches: Ensure the latest security updates from Microsoft are installed.
- Encrypt Logs: Use encryption for log files to prevent unauthorized access.
- Restrict Physical Access: Implement physical security measures to limit access to critical systems.
- Audit Logs: Regularly review and sanitize log files to remove sensitive data.
Commands:
- Check Log Files:
strings /path/to/ntfs/logfile.log | grep "sensitive_keyword"
- Encrypt Logs:
cipher /E /A /I /H "C:\path\to\logs"
- Sanitize Logs:
(Get-Content "C:\path\to\logs\logfile.log") -replace "sensitive_data", "" | Set-Content "C:\path\to\logs\logfile.log"
Code:
- Python Script to Detect Sensitive Data in Logs:
import re def scan_logs(file_path): sensitive_keywords = [bash] with open(file_path, "r") as log_file: for line in log_file: for keyword in sensitive_keywords: if re.search(keyword, line, re.IGNORECASE): print(f"Sensitive data found: {line.strip()}") break scan_logs("C:/path/to/logs/logfile.log") - PowerShell Script to Encrypt Logs:
$logPath = "C:\path\to\logs" Get-ChildItem -Path $logPath -Recurse | ForEach-Object { cipher /E $_.FullName }
Analytics:
- CVSS Score: 9.1 (Critical)
- Attack Vector: Physical
- Impact: High confidentiality risk due to sensitive data exposure.
- Mitigation Complexity: Low (requires patching and configuration changes).
By following these steps, organizations can mitigate the risks associated with CVE-2025-24984 and protect their systems from information disclosure attacks.
