CVE-2025-15435Public exploitNetwork attack vector

Unauthenticated SQL injection via Report parameter

Published Jan 2, 2026 · Updated Jan 2, 2026

SQL injection in Yonyou KSOA 9.0 allows remote attackers to access or alter database data through the Report parameter. The /worksheet/work_update.jsp endpoint places the unauthenticated Report GET value into an SQL query without adequate validation or neutralization, permitting stacked queries. Exploitation requires network access to that endpoint and no account or user interaction; resulting database operations remain bounded by the application's database privileges.
