Joomla未授权访问漏洞|CVE-2023-23752复现及修复

 

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 __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/
