CVE-2025-14106
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary commands on ZSPACE Q2C NAS devices by injecting malicious input into the safe_dir parameter of the HTTP POST request handler. Attackers can exploit this without authentication to gain full control of affected systems. All users running vulnerable versions of ZSPACE Q2C NAS are affected.
💻 Affected Systems
- ZSPACE Q2C NAS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to install malware, steal data, pivot to other systems, or render the NAS unusable.
Likely Case
Remote code execution leading to data theft, ransomware deployment, or unauthorized access to stored files.
If Mitigated
Limited impact if network segmentation and strict firewall rules prevent external access to the vulnerable endpoint.
🎯 Exploit Status
The exploit is publicly available and requires minimal technical skill to execute against vulnerable systems.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - vendor plans to release a fix but hasn't specified version
Vendor Advisory: None provided in references
Restart Required: Yes
Instructions:
1. Monitor vendor announcements for patch release. 2. Apply vendor-provided update when available. 3. Restart NAS device after patching.
🔧 Temporary Workarounds
Block Vulnerable Endpoint
linuxUse firewall or web application firewall to block access to /v2/file/safe/close endpoint
iptables -A INPUT -p tcp --dport 80 -m string --string "/v2/file/safe/close" --algo bm -j DROP
iptables -A INPUT -p tcp --dport 443 -m string --string "/v2/file/safe/close" --algo bm -j DROP
Network Segmentation
allIsolate NAS device from internet and restrict internal access
🧯 If You Can't Patch
- Disable the vulnerable web interface entirely if not required for operations
- Implement strict network access controls to limit which systems can communicate with the NAS
🔍 How to Verify
Check if Vulnerable:
Check NAS web interface version in admin panel or run: grep -i version /etc/*release* on the deviceCheck Version:
Check web admin interface or SSH into device and check system version filesVerify Fix Applied:
After vendor patch, verify version is above 1.1.0210050 and test the vulnerable endpoint with safe input📡 Detection & Monitoring
Log Indicators:
- HTTP POST requests to /v2/file/safe/close with unusual safe_dir parameters
- System logs showing unexpected command execution or process creation
Network Indicators:
- HTTP traffic to NAS on port 80/443 containing command injection patterns in POST data
- Outbound connections from NAS to suspicious external IPs
SIEM Query:
source="nas_logs" AND (uri="/v2/file/safe/close" AND (safe_dir="*;*" OR safe_dir="*|*" OR safe_dir="*`*"))
