Authenticated SQL injection via concatenated usercode parameter
Published Dec 7, 2025 · Updated Dec 8, 2025
SQL injection in AppServletService.class in Yonyou U8 Cloud 5.0, 5.0sp, 5.1, and 5.1sp allows remote authenticated users to alter SQL queries. The servlet selects an account data source and passes the usercode value into getUserInfo, where it is concatenated directly into an SQL statement. Low-privileged access is required; successful injection can expose, change, or disrupt data available to the application account.
