CWE-619 数据库游标悬挂（游标注入）

Dangling Database Cursor ('Cursor Injection')

结构: Simple

Abstraction: Base

状态: Incomplete

被利用可能性: unkown

基本描述

If a database cursor is not closed properly, then it could become accessible to other users while retaining the same privileges that were originally assigned, leaving the cursor "dangling."

扩展描述

For example, an improper dangling cursor could arise from unhandled exceptions. The impact of the issue depends on the cursor's role, but SQL injection attacks are commonly possible.
