CVE-2025-14106 is a command injection vulnerability identified in the ZSPACE Q2C NAS device, version 1.1.0210050 and earlier. The flaw exists in the HTTP POST request handler for the endpoint /v2/file/safe/close, specifically within the zfilev2_api.CloseSafe function. The vulnerability is triggered by manipulation of the safe_dir parameter, which is not properly sanitized before being used in system-level commands. This allows a remote attacker to inject arbitrary commands that the NAS device executes with elevated privileges. The attack vector requires no user interaction and no prior authentication, making it highly accessible to attackers with network access to the device. The CVSS 4.0 score of 8.7 reflects the critical nature of this vulnerability, with high impact on confidentiality, integrity, and availability. Although the vendor was notified early, no patch or response has been provided, and a public exploit is available, increasing the likelihood of exploitation. The vulnerability affects the core file management functionality of the NAS, potentially allowing attackers to gain full control over the device, exfiltrate data, or disrupt services. The lack of authentication and ease of exploitation make this a severe threat to organizations relying on ZSPACE Q2C NAS for storage and file sharing.

For European organizations, exploitation of CVE-2025-14106 could lead to complete compromise of affected NAS devices, resulting in unauthorized data access, data manipulation, or destruction. Confidential business information stored on these devices could be exfiltrated, leading to data breaches and regulatory non-compliance under GDPR. Integrity of stored data could be undermined, affecting operational reliability and trustworthiness of critical files. Availability could be disrupted by attackers executing destructive commands or deploying ransomware. Given that NAS devices often serve as centralized storage for multiple departments, the impact could cascade across organizational units. The presence of a public exploit and lack of vendor patch increase the urgency for European entities to act swiftly. Additionally, sectors such as finance, healthcare, and government, which rely heavily on secure and available storage, face heightened risks. The reputational damage and potential financial losses from exploitation could be significant.

1. Immediately restrict network access to the ZSPACE Q2C NAS devices by implementing firewall rules that limit access to trusted management networks only. 2. Disable or block HTTP POST requests to the vulnerable endpoint /v2/file/safe/close if possible, or disable the vulnerable service temporarily. 3. Monitor network traffic and device logs for unusual commands or access patterns indicative of exploitation attempts. 4. Employ network intrusion detection/prevention systems (IDS/IPS) with signatures tuned to detect exploitation attempts targeting this vulnerability. 5. Isolate affected NAS devices from critical networks until a vendor patch or official remediation is available. 6. Conduct an inventory to identify all ZSPACE Q2C NAS devices in use and verify their firmware versions. 7. Engage with ZSPACE support channels persistently to obtain patch timelines or mitigation guidance. 8. Consider deploying compensating controls such as application-layer gateways or reverse proxies that can sanitize or block malicious inputs. 9. Prepare incident response plans specific to NAS compromise scenarios to enable rapid containment and recovery. 10. Educate IT staff about this vulnerability and the importance of limiting exposure of NAS management interfaces to untrusted networks.
