Unauthenticated SQL injection via concatenated id parameter
Published Jan 2, 2026 · Updated Jan 2, 2026
SQL injection in Yonyou KSOA 9.0 allows remote attackers to manipulate database queries through the id parameter of del_user.jsp. The JSP directly concatenates untrusted GET input into a backend SQL query without validation or parameterization. No login or user interaction is required; the published time-delay payload demonstrates stacked-query execution against Microsoft SQL Server.
