CVE-2026-1178 is a SQL injection vulnerability identified in Yonyou KSOA version 9.0, specifically within the /kmf/select.jsp component that handles HTTP GET parameters. The vulnerability arises from improper sanitization of the 'folderid' parameter, allowing an attacker to inject malicious SQL queries remotely without requiring authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of service. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of exploitation (network accessible, no privileges or user interaction needed) and the impact on confidentiality, integrity, and availability, albeit with limited scope and no scope change. The vendor, Yonyou, was contacted but has not issued a patch or official response, increasing the risk of exploitation as public exploit information is available. The vulnerability affects a widely used enterprise application in China and other Asian markets, where Yonyou has significant penetration. Without remediation, attackers could leverage this flaw to compromise sensitive business data or disrupt operations.

The SQL injection vulnerability in Yonyou KSOA 9.0 can lead to unauthorized disclosure, modification, or deletion of sensitive data stored in backend databases. This compromises confidentiality and integrity, potentially exposing proprietary or personal information. Additionally, attackers could disrupt application availability by executing destructive queries or causing database errors. Given the remote, unauthenticated nature of the exploit, any exposed instance of the vulnerable software is at risk. Organizations relying on Yonyou KSOA for critical business functions may face operational disruptions, regulatory compliance issues, and reputational damage. The lack of vendor response and patch availability increases the window of exposure, making exploitation more likely. Industries such as finance, government, and manufacturing using Yonyou products are particularly vulnerable to targeted attacks leveraging this flaw.

1. Implement strict input validation and sanitization on the 'folderid' parameter to prevent malicious SQL code injection. 2. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the /kmf/select.jsp endpoint. 3. Conduct thorough code reviews and security testing of all user input handling components within Yonyou KSOA. 4. Monitor application logs and network traffic for unusual query patterns or repeated access attempts to the vulnerable parameter. 5. Isolate or restrict access to the affected application components via network segmentation or access control lists to limit exposure. 6. Engage with Yonyou support channels for updates or patches, and consider applying custom patches or workarounds if feasible. 7. Plan for an incident response strategy in case exploitation is detected, including database integrity checks and backups. 8. Educate developers and administrators about secure coding practices and the risks of SQL injection vulnerabilities.
