CVE-2025-8907

7.0 HIGH

📋 TL;DR

This vulnerability in H3C M2 NAS V100R006 allows local attackers to execute code with elevated privileges through the webserver configuration component. Only products no longer supported by the vendor are affected, and exploitation requires local access with high complexity.

💻 Affected Systems

Products:
  • H3C M2 NAS
Versions: V100R006
Operating Systems: Embedded NAS OS
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects products no longer supported by the vendor. According to vendor, device only has configuration files without actual boa functionality, making anonymous access/upload impossible.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Local attacker gains root/system-level privileges on the NAS device, potentially compromising all stored data and using the device as a pivot point in the network.

🟠

Likely Case

Limited impact due to requirement for local access and high exploitation complexity; most likely scenario involves authorized but malicious users escalating privileges.

🟢

If Mitigated

With proper access controls and network segmentation, impact is minimal as exploitation requires local access.

🌐 Internet-Facing: LOW
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: HIGH

Exploit has been publicly disclosed and may be used. Attack requires local access and manipulation of webserver configuration component.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: N/A

Vendor Advisory: N/A

Restart Required: No

Instructions:

No official patch available as product is no longer supported by vendor. Consider replacement or isolation strategies.

🔧 Temporary Workarounds

Network Isolation

all

Isolate affected NAS devices from critical network segments and restrict access to authorized users only.

Access Control Hardening

all

Implement strict local access controls and monitor for unauthorized configuration changes.

🧯 If You Can't Patch

  • Decommission affected devices and replace with supported hardware
  • Implement network segmentation to isolate affected devices from critical systems

🔍 How to Verify

Check if Vulnerable:

Check device model and firmware version. If H3C M2 NAS with V100R006 firmware, device is vulnerable.

Check Version:

Check device web interface or console for firmware version information

Verify Fix Applied:

No fix available to verify. Consider device replacement as primary remediation.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized configuration changes to webserver settings
  • Privilege escalation attempts
  • Unusual local user activity

Network Indicators:

  • Unexpected network traffic from NAS device
  • Connection attempts to restricted services

SIEM Query:

Search for events from H3C M2 NAS devices with configuration changes or privilege escalation indicators
