CVE-2025-14107
📋 TL;DR
This CVE describes a command injection vulnerability in ZSPACE Q2C NAS devices that allows remote attackers to execute arbitrary commands on affected systems. The vulnerability exists in the HTTP POST request handler for the safe status function, where user-controlled input is passed to system commands without proper sanitization. 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 execute arbitrary commands with system privileges, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Remote code execution leading to unauthorized access, data exfiltration, or use as a pivot point for lateral movement within the network.
If Mitigated
Limited impact if proper network segmentation and access controls prevent exploitation attempts from reaching vulnerable systems.
🎯 Exploit Status
Exploit code has been publicly released and requires minimal technical skill to execute. The vulnerability is in a web-accessible endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not yet released
Vendor Advisory: Not available
Restart Required: Yes
Instructions:
1. Monitor vendor announcements for patch release. 2. Apply vendor-provided update when available. 3. Restart the NAS device after patching.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to the NAS device to only trusted IP addresses or networks.
Use firewall rules to block external access to port 80/443 on the NAS
Disable Vulnerable Endpoint
allBlock or disable access to the vulnerable /v2/file/safe/status endpoint if possible.
Use web server configuration or application firewall to block POST requests to /v2/file/safe/status
🧯 If You Can't Patch
- Isolate the NAS device in a separate network segment with strict access controls
- Implement network-based intrusion detection/prevention systems to monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check the NAS device version via web interface or SSH. If version is 1.1.0210050 or earlier, the device is vulnerable.Check Version:
Check web interface admin panel or SSH into device and check system versionVerify Fix Applied:
After vendor patch is applied, verify version is higher than 1.1.0210050 and test the vulnerable endpoint with safe input validation.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /v2/file/safe/status with shell metacharacters
- System command execution from web process
- Failed authentication attempts followed by exploitation attempts
Network Indicators:
- HTTP POST requests to /v2/file/safe/status containing shell commands or special characters
- Outbound connections from NAS to unusual external IPs
SIEM Query:
source="nas_logs" AND (url="/v2/file/safe/status" AND method="POST" AND (content CONTAINS "|" OR content CONTAINS ";" OR content CONTAINS "`" OR content CONTAINS "$"))
