CVE-2025-34059 is a high-severity SQL injection vulnerability identified in the Zhejiang Dahua Technology Co., Ltd. Smart Cloud Gateway Registration Management Platform. The flaw exists specifically in the /index.php/User/doLogin endpoint, where the username parameter is not properly sanitized. This improper neutralization of special elements used in SQL commands (CWE-89) allows unauthenticated attackers to inject arbitrary SQL statements. Exploiting this vulnerability could lead to unauthorized disclosure of sensitive information (CWE-200) stored in the backend database. The vulnerability is notable because it requires no authentication or user interaction, and the attack vector is network accessible (AV:N). The CVSS 4.0 base score is 8.7, reflecting its high impact on confidentiality with no impact on integrity or availability. The vulnerability affects version 0 of the product, which likely refers to initial or early releases. No patches or known exploits in the wild are currently reported, but the presence of this vulnerability in a gateway registration management platform—often a critical component in IoT or cloud device management—raises significant security concerns. Attackers could leverage this flaw to extract user credentials, configuration data, or other sensitive information, potentially enabling further attacks or unauthorized access to connected systems. Given the nature of Dahua’s products, which are widely used in surveillance and security infrastructure, this vulnerability could have cascading effects if exploited.

For European organizations, the impact of this vulnerability could be substantial, especially for those using Dahua’s Smart Cloud Gateway Registration Management Platform to manage IoT devices, security cameras, or cloud-connected infrastructure. Successful exploitation could lead to leakage of sensitive user data, credentials, or configuration details, undermining the confidentiality of security systems. This could facilitate unauthorized access to surveillance systems, leading to privacy violations, data breaches, and potential disruption of security operations. Additionally, compromised gateway platforms could serve as pivot points for lateral movement within networks, increasing the risk of broader compromise. Organizations in sectors such as critical infrastructure, government, transportation, and private enterprises relying on Dahua’s solutions would be particularly vulnerable. The lack of authentication and user interaction requirements means attackers can exploit the vulnerability remotely and at scale, increasing the threat surface. Furthermore, the exposure of sensitive information could lead to regulatory non-compliance under GDPR, resulting in legal and financial repercussions for European entities.

1. Immediate deployment of input validation and sanitization controls on the username parameter within the /index.php/User/doLogin endpoint to prevent SQL injection. 2. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. 3. Conduct thorough code reviews and security testing (including automated and manual penetration testing) of the affected platform to identify and remediate similar injection flaws. 4. Restrict network access to the management platform to trusted IP ranges and enforce strong network segmentation to limit exposure. 5. Monitor logs for unusual query patterns or failed login attempts indicative of injection attempts. 6. Engage with Zhejiang Dahua Technology for official patches or updates and prioritize their deployment once available. 7. Consider compensating controls such as database user privilege restrictions to minimize data exposure in case of injection. 8. Educate security teams on this specific vulnerability to enhance detection and incident response readiness.
