CVE-2025-3956 is a SQL Injection vulnerability identified in version 1.4.0 of the novel-cloud software developed by 201206030. The vulnerability specifically affects the RestResp function within the BookInfoMapper.xml file located in the novel-book-service module. The flaw arises from improper sanitization or validation of user-supplied input that is incorporated into SQL queries, allowing an attacker to inject malicious SQL code. This injection can be performed remotely without requiring user interaction or authentication, increasing the attack surface. The vulnerability was publicly disclosed on April 27, 2025, with the vendor not responding to early notifications. Although the CVSS 4.0 base score is 5.3 (medium severity), the vulnerability allows remote attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of service. The lack of vendor patch or mitigation guidance increases the risk for organizations using this specific version of novel-cloud. No known exploits are currently reported in the wild, but public disclosure raises the likelihood of exploitation attempts. The vulnerability does not require user interaction or privileges, but the CVSS vector indicates a low impact on confidentiality, integrity, and availability, suggesting that exploitation may be limited in scope or impact depending on the database and application context. Novel-cloud is a cloud-based service platform, and the affected module relates to book information management, which may be part of broader content or data management systems.

For European organizations utilizing novel-cloud 1.4.0, this vulnerability poses a risk of unauthorized access or manipulation of sensitive data stored in backend databases. The SQL injection could allow attackers to extract confidential information, alter records, or disrupt service availability, potentially affecting business operations and data integrity. Organizations in sectors relying on cloud-based content management or digital libraries could face data breaches or operational interruptions. Given the remote and unauthenticated nature of the exploit, attackers could leverage this vulnerability to gain footholds in enterprise environments, escalate privileges, or move laterally. The absence of vendor response and patches increases exposure time, raising the risk of targeted attacks. Compliance with European data protection regulations (e.g., GDPR) could be jeopardized if personal or sensitive data is compromised. Additionally, organizations may face reputational damage and financial penalties if breaches occur due to this vulnerability.

1. Immediate mitigation should include isolating or disabling the affected novel-cloud 1.4.0 instances until a patch or vendor guidance is available. 2. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the RestResp function or related endpoints. 3. Conduct thorough input validation and sanitization on all user inputs interacting with the novel-book-service module, applying parameterized queries or prepared statements where possible. 4. Monitor application logs and database query logs for anomalous or suspicious SQL activity indicative of injection attempts. 5. Restrict database user privileges to the minimum necessary, limiting the impact of potential injection exploitation. 6. Consider deploying runtime application self-protection (RASP) tools that can detect and block injection attacks in real time. 7. Engage in threat hunting exercises focused on novel-cloud deployments to identify any signs of compromise. 8. Plan for an upgrade or migration to a patched or alternative solution once available, and maintain communication channels with the vendor or community for updates. 9. Educate development and security teams about secure coding practices to prevent similar vulnerabilities in custom extensions or integrations.
