CWE-1049 大数据表中的数据查询操作过多

Excessive Data Query Operations in a Large Data Table

结构: Simple

Abstraction: Base

状态: Incomplete

被利用可能性: unkown

基本描述

The software performs a data query with a large number of joins
and sub-queries on a large data table.

扩展描述

This issue can make the software perform more slowly. If the relevant code is reachable by an attacker, then this performance problem might introduce a vulnerability.

While the interpretation of "large data table" and "large number of joins or sub-queries" may vary for each product or developer, CISQ recommends a default of 1 million rows for a "large" data table, a default minimum of 5 joins, and a default minimum of 3 sub-queries.
