Sourcecodester Fantastic Blog CMS v1.0 SQL 注入（CVE-2022-28512）-阿里云开发者社区

前言

CVE-2022-28060 是 Victor CMS v1.0 中的一个SQL注入。该存在于 /includes/login.php 文件中的 user_name 参数。可以通过发送特制的 SQL 语句，利用这个执行未授权的数据库操作，从而访问或修改数据库中的敏感信息。

详细信息

类型：SQL注入
受影响的组件：Victor CMS v1.0
途径：远程攻击者可以利用该，通过发送特制的请求来执行任意的 SQL 语句。
严重性：高 (CVSS v3 基础分数：7.5)

解决方案

使用准备好的语句：采用预编译的 SQL 语句或参数化查询来处理 SQL 请求。
输入验证：对所有用户输入进行严格的验证和过滤，确保只接受符合预期格式的输入。
最小权限原则：为数据库用户分配最低的权限，确保即使发生注入，也无法获得过多的权限

复现

打开

根据题目手动构造 URL

http://eci-2zehz8yh4xe8fzah182w.cloudeci1.ichunqiu.com/single.php?id=1

原首页可以看到是有登录的

现在咱们能直接构造 URL 访问目标页面说明没有用户验证，直接上 SQLMap 跑它
