Overview
A high-severity command injection vulnerability, identified as CVE-2025-14107, has been discovered in ZSPACE Q2C NAS devices up to version 1.1.0210050. This flaw allows remote attackers to execute arbitrary commands on the affected system. The vulnerability resides within the zfilev2_api.SafeStatus function of the /v2/file/safe/status endpoint, specifically through manipulation of the safe_dir argument via an HTTP POST request.
The vendor has been contacted but has not provided a response or patch at the time of writing, and a public exploit is available, making this vulnerability especially critical.
Technical Details
The vulnerability stems from insufficient input validation on the safe_dir parameter within the zfilev2_api.SafeStatus function. An attacker can inject malicious commands into this parameter, which are then executed by the system. This command injection can be achieved through a crafted HTTP POST request to the /v2/file/safe/status endpoint.
The lack of response from the vendor makes a detailed root cause analysis impossible without access to the affected device. However, the description strongly indicates a failure to sanitize user-provided input before passing it to a system call.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-14107 is 8.8, indicating a HIGH severity vulnerability. The CVSS vector likely includes the following characteristics:
- Attack Vector: Network (AV:N) – The vulnerability can be exploited remotely.
- Attack Complexity: Low (AC:L) – The exploitation requires minimal effort.
- Privileges Required: None (PR:N) – No authentication is required to exploit the vulnerability.
- User Interaction: None (UI:N) – No user interaction is needed to trigger the vulnerability.
- Scope: Changed (S:C) – An attacker can execute code in a different security context.
- Confidentiality Impact: High (C:H) – The attacker can gain access to sensitive information.
- Integrity Impact: High (I:H) – The attacker can modify system data or execute arbitrary code.
- Availability Impact: High (A:H) – The attacker can cause a denial of service (DoS) condition.
Possible Impact
Successful exploitation of CVE-2025-14107 can have severe consequences, including:
- Complete System Compromise: Attackers can gain full control over the ZSPACE Q2C NAS device.
- Data Theft and Manipulation: Sensitive data stored on the NAS can be accessed, modified, or deleted.
- Malware Deployment: The NAS can be used as a platform to deploy malware to other devices on the network.
- Denial of Service (DoS): Attackers can render the NAS unavailable to legitimate users.
- Lateral Movement: If the NAS is connected to a wider network, attackers can use it as a stepping stone to compromise other systems.
Mitigation or Patch Steps
Unfortunately, since the vendor has not released a patch or acknowledged the vulnerability, definitive mitigation steps are limited. However, the following steps can be taken to reduce the risk:
- Network Segmentation: Isolate the ZSPACE Q2C NAS device from critical network segments.
- Access Control Lists (ACLs): Implement strict ACLs to limit access to the NAS device. Only allow trusted IP addresses or networks to communicate with the device.
- Web Application Firewall (WAF): If possible, place a WAF in front of the NAS to filter malicious requests.
- Disable Unnecessary Services: Disable any unnecessary services or features on the NAS device.
- Monitor Network Traffic: Closely monitor network traffic to and from the NAS device for suspicious activity.
- Consider Alternative Solutions: If possible, consider migrating to a more secure NAS solution from a vendor that actively addresses security vulnerabilities.
Important: Until a patch is released, complete protection against CVE-2025-14107 is not possible. The above steps are only risk-reduction measures.
