CVE-2026-1132 is a SQL injection vulnerability identified in Yonyou KSOA version 9.0, a widely used enterprise application platform. The vulnerability resides in the HTTP GET parameter handler of the /kmf/edit_folder.jsp file, specifically in the folderid parameter. An attacker can remotely manipulate this parameter to inject malicious SQL queries without requiring authentication or user interaction. This allows unauthorized access to backend databases, potentially leading to data leakage, unauthorized data modification, or denial of service. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity, with network attack vector, low attack complexity, and no privileges or user interaction needed. Despite early vendor notification, no patches or mitigations have been released, and a public exploit is available, increasing the risk of exploitation. The vulnerability affects the confidentiality, integrity, and availability of the system's data, posing a significant risk to organizations relying on Yonyou KSOA 9.0 for critical business operations.

The SQL injection vulnerability in Yonyou KSOA 9.0 can have severe consequences for affected organizations. Exploitation could lead to unauthorized disclosure of sensitive business data, modification or deletion of critical records, and potential disruption of service availability. Attackers could leverage this flaw to escalate privileges within the database, pivot to other internal systems, or implant persistent backdoors. Given that Yonyou KSOA is an enterprise platform used primarily in China and other Asian markets, organizations in these regions are at higher risk. The lack of vendor response and patch availability increases the window of exposure, potentially inviting targeted attacks or opportunistic exploitation. The vulnerability undermines trust in the affected systems and could result in regulatory penalties if sensitive data is compromised.

Organizations should immediately implement input validation and parameterized queries or prepared statements within their Yonyou KSOA 9.0 deployments to prevent SQL injection. If source code modification is not feasible, deploying a web application firewall (WAF) with custom rules to detect and block malicious SQL injection payloads targeting the folderid parameter is recommended. Network segmentation and strict access controls should be enforced to limit exposure of the affected application to untrusted networks. Monitoring and logging of database queries and web requests can help detect exploitation attempts early. Organizations should also engage with Yonyou for official patches or updates and consider upgrading to a newer, patched version once available. Regular security assessments and penetration testing focused on injection flaws are advised to identify and remediate similar vulnerabilities proactively.
