CVE-2025-13171 is a SQL injection vulnerability identified in the 2023 version of ZZCMS, a content management system. The vulnerability exists in the /admin/wangkan_list.php file, where the 'keyword' parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This injection can be performed remotely without authentication or user interaction, making it easier to exploit. The vulnerability can lead to unauthorized access to the database, enabling attackers to read, modify, or delete data, potentially compromising the confidentiality, integrity, and availability of the system. The CVSS 4.0 score is 5.3 (medium), reflecting that while the attack vector is network-based and requires no user interaction, it does require low privileges and results in limited impact on confidentiality, integrity, and availability. No patches have been officially released yet, and no known exploits are actively used in the wild, but a public exploit is available, increasing the risk of exploitation. This vulnerability is particularly concerning for organizations that expose their ZZCMS admin interfaces to the internet without adequate protections.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive data stored within ZZCMS databases, including potentially user information, content, or administrative data. This could result in data breaches, defacement of websites, or disruption of services. Organizations relying on ZZCMS for critical content management may face reputational damage and compliance issues, especially under GDPR regulations concerning data protection. The medium severity indicates a moderate risk, but the availability of a public exploit and the remote attack vector increase the urgency for mitigation. Attackers could leverage this vulnerability to pivot within networks or escalate privileges if combined with other vulnerabilities. The impact is more significant for organizations with publicly accessible admin panels or weak network segmentation.

1. Immediately restrict access to the /admin/wangkan_list.php endpoint by IP whitelisting or VPN-only access to limit exposure. 2. Implement web application firewalls (WAF) with custom rules to detect and block SQL injection attempts targeting the 'keyword' parameter. 3. Apply input validation and sanitization on all user-supplied inputs, especially the 'keyword' parameter, using allowlists and escaping techniques. 4. Modify the application code to use parameterized queries or prepared statements to prevent SQL injection. 5. Monitor logs for unusual database query patterns or repeated failed attempts targeting the admin interface. 6. If possible, isolate the CMS database with least privilege access and network segmentation to limit lateral movement. 7. Stay alert for official patches or updates from ZZCMS and apply them promptly once available. 8. Conduct security audits and penetration testing focusing on the admin interface and input handling.
