CVE-2025-4514 is a SQL Injection vulnerability identified in Zhengzhou Jiuhua Electronic Technology's mayicms product, specifically affecting version 5.8E and earlier. The vulnerability resides in an unknown functionality within the /javascript.php file, where the manipulation of the 'Value' argument allows an attacker to inject malicious SQL code. This flaw can be exploited remotely without requiring user interaction or authentication, as indicated by the CVSS 4.0 vector (AV:N/AC:L/AT:N/UI:N/PR:L). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, potentially allowing attackers to extract sensitive data, modify or delete records, or disrupt application functionality. Despite the CVSS score of 5.3 (medium severity), the vulnerability's remote exploitability and lack of required user interaction make it a significant risk. No public exploits are currently known to be active in the wild, and no patches have been officially released yet. The vulnerability was publicly disclosed shortly after being reserved, indicating a rapid publication cycle. The affected product, mayicms, is a content management system likely used by organizations for website and content management, which may contain sensitive business or customer data. The lack of detailed CWE classification limits the granularity of technical analysis, but the core issue remains a classic SQL injection vector through unsanitized input in a web application endpoint.

For European organizations using mayicms version 5.8E or earlier, this vulnerability poses a risk of unauthorized data access and manipulation. Successful exploitation could lead to data breaches involving personal data protected under GDPR, resulting in regulatory penalties and reputational damage. The integrity of web content and backend databases could be compromised, affecting business operations and customer trust. Additionally, attackers could leverage this vulnerability to pivot into internal networks or deploy further attacks such as ransomware. Given the remote exploitability and no need for user interaction, attackers can automate exploitation attempts, increasing the likelihood of compromise. Organizations in sectors with high data sensitivity, such as finance, healthcare, and government, are particularly at risk. The absence of known active exploits currently provides a window for mitigation, but the public disclosure increases the risk of future exploitation.

European organizations should immediately identify any deployments of mayicms version 5.8E or earlier within their infrastructure. As no official patches are currently available, organizations should implement the following specific mitigations: 1) Apply Web Application Firewall (WAF) rules tailored to detect and block SQL injection patterns targeting the /javascript.php endpoint, especially focusing on the 'Value' parameter. 2) Conduct thorough input validation and sanitization on all user-supplied inputs, particularly those interacting with database queries, to prevent injection. 3) Restrict database user privileges associated with the web application to the minimum necessary, limiting potential damage from exploitation. 4) Monitor application logs and network traffic for unusual or suspicious activity indicative of SQL injection attempts. 5) Consider temporarily disabling or restricting access to the vulnerable functionality if feasible until a patch is released. 6) Engage with the vendor or community for updates or unofficial patches and plan for prompt application once available. 7) Conduct security assessments and penetration testing focused on injection vulnerabilities to identify and remediate similar issues proactively.
