CVE-2025-15424 identifies a SQL injection vulnerability in Yonyou KSOA 9.0, a widely used enterprise management software suite. The flaw exists in the HTTP GET parameter handler within the /worksheet/agent_worksdel.jsp file, where the 'ID' parameter is improperly sanitized. This allows an unauthenticated remote attacker to inject malicious SQL queries by manipulating the 'ID' argument, potentially leading to unauthorized data access, modification, or deletion in the backend database. The vulnerability does not require any privileges or user interaction, increasing its exploitability. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the ease of exploitation and partial impact on confidentiality, integrity, and availability. Although the vendor was notified early, no response or patch has been issued, and public exploit code is available, raising the risk of future attacks. The vulnerability affects only version 9.0 of KSOA, and no other versions are currently reported as vulnerable. The lack of vendor remediation and public exploit availability necessitate immediate defensive measures by affected organizations.

The SQL injection vulnerability in Yonyou KSOA 9.0 can lead to unauthorized access to sensitive enterprise data, including financial, operational, and personnel information. Attackers could alter or delete critical database records, disrupting business operations and causing data integrity issues. Confidential information leakage could result in regulatory compliance violations and reputational damage. Since the exploit requires no authentication or user interaction, the attack surface is broad, enabling remote attackers to target exposed KSOA instances over the internet. The absence of vendor patches increases the window of exposure, potentially leading to widespread exploitation once threat actors develop reliable attack tools. Organizations relying on KSOA for core business functions may experience operational downtime, data loss, and increased incident response costs. The medium severity rating indicates a significant but not catastrophic risk, emphasizing the need for timely mitigation.

1. Implement strict input validation and parameter sanitization on the 'ID' parameter at the application or web server level to block malicious SQL payloads. 2. Deploy a Web Application Firewall (WAF) with custom rules to detect and block SQL injection attempts targeting the vulnerable endpoint. 3. Restrict external access to the KSOA application by using network segmentation and VPNs to limit exposure to trusted users only. 4. Monitor application logs and network traffic for unusual query patterns or repeated access attempts to /worksheet/agent_worksdel.jsp. 5. Conduct a thorough security audit of the KSOA deployment to identify other potential injection points or misconfigurations. 6. Engage with Yonyou support channels regularly to obtain updates or patches once available. 7. Consider temporary application-layer mitigations such as disabling or restricting the vulnerable functionality if feasible. 8. Educate IT and security teams about this vulnerability and ensure incident response plans include steps for SQL injection attacks. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and application context.
