CVE-2026-1178 identifies a SQL injection vulnerability in Yonyou KSOA 9.0, a business application platform widely used in enterprise environments. The vulnerability exists in the HTTP GET parameter handler of the /kmf/select.jsp file, where the 'folderid' parameter is not properly sanitized before being incorporated into SQL queries. This allows an unauthenticated remote attacker to inject malicious SQL code, potentially leading to unauthorized data access, data modification, or disruption of service. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with an attack vector of network (remote), low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. The vendor was notified but has not issued a patch or response, increasing the risk for organizations relying on this software. Although no known exploits are currently active in the wild, the public disclosure of the vulnerability means attackers could develop exploits. The lack of authentication and user interaction requirements makes this vulnerability particularly concerning for exposed web-facing instances of Yonyou KSOA 9.0. Organizations should assess their exposure and implement mitigations promptly to reduce risk.

For European organizations, exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive business data, manipulation or deletion of critical records, and potential disruption of business operations. Given Yonyou KSOA's role in enterprise resource planning and business process management, a successful attack could compromise financial data, intellectual property, and operational workflows. The medium severity rating reflects limited but meaningful impacts on confidentiality, integrity, and availability, which could cascade into regulatory compliance issues under GDPR if personal data is exposed. The remote and unauthenticated nature of the attack vector increases the risk for organizations with internet-facing deployments. Additionally, the vendor's lack of response and absence of patches heighten the urgency for European entities to implement compensating controls. Industries such as manufacturing, finance, and government agencies using Yonyou KSOA are particularly vulnerable to operational disruption and data breaches stemming from this flaw.

Since no official patch is currently available from the vendor, European organizations should implement the following specific mitigations: 1) Employ strict input validation and sanitization on the 'folderid' parameter at the web application or proxy level to block malicious SQL payloads. 2) Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the /kmf/select.jsp endpoint. 3) Restrict network access to the Yonyou KSOA application, limiting exposure to trusted internal networks or VPNs to reduce attack surface. 4) Monitor database logs and application logs for unusual queries or error messages indicative of injection attempts. 5) Conduct thorough code reviews and penetration testing focused on SQL injection vectors in the affected module. 6) Prepare incident response plans to quickly contain and remediate any exploitation. 7) Engage with the vendor or community for updates and patches, and plan for timely application once available. 8) Consider isolating or segmenting the affected application components to minimize lateral movement in case of compromise.
