Deeper analysis
CVE-2026-1124 is a SQL injection vulnerability (CWE-74, CWE-89) in Yonyou KSOA 9.0. The issue affects an unknown functionality within the file /worksheet/work_report.jsp, specifically the HTTP GET Parameter Handler component. Attackers can exploit it by manipulating the "ID" argument via HTTP GET requests, leading to SQL code injection.
Remote exploitation is possible with no authentication required, as indicated by the CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Unauthenticated attackers with network access can trigger the vulnerability with low complexity, achieving low-level impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or disruption.
References from VulDB and a GitHub issue disclose the vulnerability details and note that an exploit has been publicly released, enabling potential attacks. The vendor was contacted early regarding the issue but provided no response, and no patches or official mitigations are mentioned.
Notable context includes the public availability of the exploit, increasing the risk of real-world attacks against exposed Yonyou KSOA 9.0 instances.

Directly requires validation of the untrusted "ID" HTTP GET parameter before it is used in SQL statements, blocking the injection vector in work_report.jsp.
Boundary-protection devices (e.g., WAF rules) can inspect and drop HTTP requests containing SQL metacharacters targeting the exposed /worksheet/work_report.jsp endpoint.
Continuous monitoring of web-server and database logs can identify anomalous SQL syntax or error patterns indicative of attempted exploitation of the public CVE-2026-1124 payload.
