一、Apache Superset 简介

Apache Superset 是美国阿帕奇（Apache）基金会的一个数据可视化和数据探索平台。

二、漏洞描述

Apache Superset 是美国阿帕奇（Apache）基金会的一个数据可视化和数据探索平台。Apache Superset 2.0.1 版本及之前版本存在安全漏洞。攻击者利用该漏洞验证和访问未经授权的资源。

CVE 编号:CVE-2023-27524
CNNVD 编号:CNNVD-202304-1915
CNVD 编号:

三、影响版本

Apache Superset 2.0.1 版本及之前版本

四、fofa 查询语句

“Apache Superset”

五、漏洞复现

漏洞利用工具 ：https://github.com/horizon3ai/CVE-2023-27524
下载该软件：
然后执行如下命令，-u后面跟你想要检测的地址。

python3 CVE-2023-27524.py -u http://127.0.0.1/ --validate
若存在漏洞这里会爆出一个cookie值

然后访问漏洞url,使用brupsuite截断数据包，替换上面爆出来的cookie值。
替换后放开数据包，成功登录进去Apache Superset 管理后台
