CVE-2025-13171 identifies a SQL injection vulnerability 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 arbitrary SQL commands. This injection flaw can be exploited remotely without requiring user interaction or prior authentication, making it accessible to a wide range of attackers. The vulnerability impacts confidentiality, integrity, and availability, though to a limited extent (low impact on each). The CVSS 4.0 vector indicates no privileges required (PR:L means low privileges), no user interaction needed, and no scope change, but the attack complexity is low. The exploit code is publicly available, increasing the risk of exploitation despite no known active attacks reported. The vulnerability could allow attackers to extract sensitive data, modify database contents, or disrupt service availability. The lack of official patches or mitigation links suggests that organizations must implement defensive coding practices or restrict access to vulnerable endpoints. This vulnerability underscores the importance of secure input handling in web applications, especially in administrative modules that control critical content management functions.

For European organizations, the impact of CVE-2025-13171 can be significant if ZZCMS 2023 is used to manage critical websites or internal portals. Successful exploitation could lead to unauthorized data disclosure, data tampering, or partial service disruption. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), and operational interruptions. The medium severity rating reflects moderate risk, but the ease of remote exploitation without authentication raises concerns for organizations with exposed admin interfaces. Attackers could leverage this vulnerability to pivot into deeper network segments or escalate privileges if combined with other vulnerabilities. Sensitive sectors such as government, finance, healthcare, and media in Europe could be targeted due to the strategic value of their data and services. The absence of known active exploitation provides a window for proactive defense, but the public availability of exploit code increases the urgency for mitigation.

European organizations should immediately audit their use of ZZCMS 2023 and identify any exposed /admin/wangkan_list.php endpoints. Specific mitigations include: 1) Implement strict input validation and sanitization on the 'keyword' parameter to prevent SQL injection. 2) Employ parameterized queries or prepared statements in the backend code to eliminate direct SQL concatenation. 3) Restrict access to the admin interface by IP whitelisting, VPN, or multi-factor authentication to reduce exposure. 4) Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5) If possible, isolate the CMS environment from critical internal networks to limit lateral movement. 6) Engage with ZZCMS developers or community to obtain patches or updates addressing this vulnerability. 7) Conduct penetration testing focused on SQL injection vectors to verify remediation effectiveness. 8) Educate administrators on the risks of exposing admin panels publicly and enforce strong credential policies.
