CVE-2023-41282: CWE-77 in QNAP Systems Inc. QTS
An OS command injection vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow authenticated administrators to execute commands via a network. We have already fixed the vulnerability in the following versions: QTS 5.1.4.2596 build 20231128 and later QuTS hero h5.1.4.2596 build 20231128 and later QuTScloud c5.1.5.2651 and later
AI Analysis
Technical Summary
CVE-2023-41282 is an OS command injection vulnerability affecting QNAP Systems Inc.'s QTS operating system, specifically versions 5.1.x prior to 5.1.4.2596. This vulnerability is classified under CWE-77, which relates to improper neutralization of special elements used in a command ('OS Command Injection'). The flaw allows an authenticated administrator to execute arbitrary operating system commands remotely over the network. Exploitation requires administrative privileges but does not require user interaction beyond authentication. The vulnerability impacts confidentiality and integrity by enabling command execution that could lead to unauthorized data access or modification. The vulnerability has been addressed in QTS 5.1.4.2596 build 20231128 and later, as well as in QuTS hero and QuTScloud updated versions. The CVSS v3.1 base score is 5.5 (medium severity), reflecting network attack vector, low attack complexity, high privileges required, no user interaction, and partial impact on confidentiality and integrity but no impact on availability. No known exploits are currently reported in the wild. Given the nature of QNAP NAS devices as network-attached storage commonly used in enterprises and SMEs, this vulnerability could be leveraged by malicious insiders or attackers who have obtained administrative credentials to execute arbitrary commands, potentially leading to data breaches or system compromise.
Potential Impact
For European organizations, the impact of CVE-2023-41282 can be significant due to the widespread use of QNAP NAS devices for data storage, backup, and file sharing. Successful exploitation could lead to unauthorized command execution, enabling attackers to access sensitive data, alter system configurations, or deploy further malware. This could disrupt business operations, compromise data integrity, and violate data protection regulations such as GDPR. Organizations in sectors with stringent data security requirements (e.g., finance, healthcare, government) are particularly at risk. The requirement for administrative authentication limits exposure to insider threats or attackers who have already gained elevated access, but the network-accessible nature of the vulnerability means that compromised credentials could be exploited remotely. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for targeted attacks or future exploit development.
Mitigation Recommendations
European organizations should prioritize updating QNAP QTS systems to version 5.1.4.2596 or later, or the corresponding patched versions of QuTS hero and QuTScloud, to remediate this vulnerability. Beyond patching, organizations should enforce strong administrative access controls, including multi-factor authentication (MFA) for all administrator accounts to reduce the risk of credential compromise. Network segmentation should be applied to isolate NAS devices from general user networks and limit administrative access to trusted management networks or VPNs. Regular auditing of administrator account activity and logs can help detect suspicious command execution attempts. Additionally, organizations should implement strict password policies and consider using dedicated management workstations for administrative tasks. Monitoring network traffic for unusual command execution patterns and deploying endpoint detection and response (EDR) solutions on NAS devices, if supported, can provide early warning of exploitation attempts.
