CVE-2025-15425 identifies a SQL injection vulnerability in Yonyou KSOA version 9.0, a business management software widely used in enterprise environments. The flaw exists in an unspecified function within the /worksheet/del_user.jsp component, which processes HTTP GET requests. Specifically, the 'ID' parameter is not properly sanitized or validated, allowing an attacker to inject arbitrary SQL commands. This vulnerability can be exploited remotely without any authentication or user interaction, increasing the risk of automated attacks. The SQL injection could enable attackers to read, modify, or delete sensitive data stored in the backend database, potentially compromising the confidentiality, integrity, and availability of critical business information. The vendor was notified early but has not issued a patch or response, and while no known exploits are currently active in the wild, the public disclosure raises the risk of imminent exploitation. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the network attack vector, lack of required privileges, and partial impact on data confidentiality, integrity, and availability. The vulnerability affects only version 9.0 of the product, and no mitigations or patches have been officially released to date.

The SQL injection vulnerability in Yonyou KSOA 9.0 can have significant consequences for organizations relying on this software. Attackers exploiting this flaw can remotely execute arbitrary SQL queries, potentially leading to unauthorized data access, data corruption, or deletion. This compromises the confidentiality and integrity of sensitive business data, including user information and operational records. Additionally, the availability of the application or database could be disrupted if destructive queries are executed. Given that no authentication or user interaction is required, automated attacks or mass scanning campaigns could rapidly target vulnerable systems. The lack of vendor response and patches increases the window of exposure, elevating the risk of data breaches and operational disruptions. Organizations may face regulatory compliance issues, reputational damage, and financial losses if exploited. The impact is particularly critical for enterprises with sensitive or regulated data stored in Yonyou KSOA databases.

1. Immediate implementation of web application firewall (WAF) rules to detect and block suspicious SQL injection patterns targeting the 'ID' parameter in /worksheet/del_user.jsp requests. 2. Employ strict input validation and sanitization on all user-supplied parameters, especially the 'ID' parameter, to ensure only expected data types and formats are accepted. 3. Restrict database user permissions for the application to the minimum necessary, preventing unauthorized data manipulation or access beyond what is required. 4. Monitor application and database logs for unusual query patterns or errors indicative of SQL injection attempts. 5. Isolate or segment the affected application environment to limit lateral movement if exploitation occurs. 6. Engage with Yonyou support channels to request official patches or guidance and track for future updates. 7. Consider temporary disabling or restricting access to the vulnerable endpoint if feasible until a patch is available. 8. Conduct thorough security assessments and penetration testing focused on injection flaws in the application. 9. Educate development and operations teams on secure coding practices to prevent similar vulnerabilities in future releases.
