CVE-2026-1179 is a SQL injection vulnerability affecting Yonyou KSOA version 9.0, located in the HTTP GET parameter handler for the 'folderid' argument within the /kmf/user_popedom.jsp file. The vulnerability arises due to insufficient sanitization of the 'folderid' parameter, allowing an attacker to inject malicious SQL code remotely without authentication or user interaction. This can lead to unauthorized access, data leakage, or modification of the backend database. The vulnerability has a CVSS 4.0 base score of 6.9 (medium severity), reflecting its network attack vector, low complexity, and no required privileges or user interaction, but limited impact on confidentiality, integrity, and availability. The exploit code is publicly available, increasing the likelihood of exploitation despite no current reports of active attacks. The vendor Yonyou has not issued any patches or advisories, leaving users exposed. Given Yonyou's prominence in enterprise resource planning and business management software, this vulnerability poses a significant risk to organizations relying on KSOA 9.0 for critical operations. Attackers could leverage this flaw to extract sensitive business data or disrupt services, impacting organizational security and compliance.

For European organizations, exploitation of this SQL injection vulnerability could result in unauthorized disclosure of sensitive corporate data, including intellectual property, financial records, or personal data protected under GDPR. Integrity of data could be compromised, leading to corrupted records or fraudulent transactions. Availability might be affected if attackers execute destructive SQL commands or cause database crashes. The risk is heightened for sectors such as finance, manufacturing, and public administration where Yonyou KSOA is deployed. Data breaches could lead to regulatory penalties and reputational damage. The lack of vendor response and patches increases exposure duration, making timely mitigation critical. Organizations with interconnected systems may face lateral movement risks if attackers gain database access. The public availability of exploit code lowers the barrier for attackers, including cybercriminals and state-sponsored actors targeting European enterprises.

1. Implement strict input validation and parameterized queries or prepared statements in the application code to prevent SQL injection. 2. Deploy Web Application Firewalls (WAFs) with rules specifically targeting SQL injection patterns, particularly on the 'folderid' parameter. 3. Monitor database logs and web server logs for unusual query patterns or repeated failed requests targeting /kmf/user_popedom.jsp. 4. Restrict database user permissions to the minimum necessary to limit the impact of any injection. 5. Isolate the affected application components within network segments with limited access. 6. Conduct regular security assessments and penetration testing focusing on injection flaws. 7. Engage with Yonyou support channels to request official patches or guidance. 8. If possible, consider upgrading to a later version of KSOA once a patch is available. 9. Educate development and security teams about the risks of SQL injection and secure coding practices. 10. Prepare incident response plans to quickly address any exploitation attempts.
