Turn off system privileges

Root@demohost:/home/user# radosgw-admin user modify-system=0-uid=s3user {"user_id": "s3user", "display_name": "s3user", "email": "", "suspended": 0, "max_buckets": 1000, "auid": 0, "subusers": [], "keys": [{"user": "s3user" "access_key": "," secret_key ":"}]," swift_keys ": []," caps ": []," op_mask ":" read, write, delete "," default_placement ":"," placement_tags ": []," bucket_quota ": {" enabled ": false Max_size_kb:-1, max_objects:-1}, user_quota: {"enabled": false, "max_size_kb":-1, "max_objects":-1}, "temp_url_keys": []}

When the system privilege is turned on, the body of the create_bucket request returns various hidden attributes of the corresponding bucket

The test code for python is as follows

#-*-coding: utf-8-*-from boto.s3.connection import S3Connectionimport botoimport osbucket_name = 'user-bucket1'access_key =' secret_key =''endpoint =' s3.ceph.work'conn = boto.connect_s3 (aws_access_key_id=access_key, aws_secret_access_key=secret_key, host=endpoint, is_secure=False, calling_format=boto.s3.connection.OrdinaryCallingFormat (), validate_certs=True,) bucket = conn.create_bucket (bucket_name)

The body content of response is empty before enabling it.

After opening it, all the hidden metadata of bucket was exposed.

Finally, the authority of this system is very large, do not open it casually, it is easy to expand the authority and hide the disclosure of information.
