SQL报错泄漏(中危)

# 漏洞等级 中危 # 漏洞描述 由于系统后端代码未自定义SQL抛出异常,导致系统中接口请求时,缺少参数和其他原因,引发后端SQL报错,从而直接将SQL报错信息输出; # 漏洞危害 # 修复建议 后端代码自定义输出异常,禁止将SQL报错信息回显输出 # 修复代码 ```java import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.ControllerAdvice; import org.springframework.web.bind.annotation.ResponseBody; import java.sql.SQLException; @ControllerAdvice public class ExceptionHandler { private static final Logger log = LoggerFactory.getLogger(ExceptionHandler.class); @org.springframework.web.bind.annotation.ExceptionHandler({SQLException.class}) @ResponseBody public ResponseResult<Object> handleNullPointerException(SQLException e) { log.error("代码错误,sql异常:" + e); return ResultUtil.error("代码错误,sql异常"); } } ```
