Apache IoTDB: Legacy Pipe Privilege Escalation

On KEV
Description
The Legacy Pipe receiver protocol (handshake / sendPipeData) uses a
hardcoded SUPER_USER (root) identity when executing data loading and
deletion operations. A user with only SYSTEM-level privileges (such as
USE_PIPE or MAINTAIN) who does NOT have WRITE_DATA or DELETE_DATA
permissions on target databases can send specially crafted PipeData
messages through the Legacy Pipe API, resulting in data loading/deletion
operations executed as root — effectively bypassing IoTDB's permission
model entirely.
This issue affects Apache IoTDB: from 2.0.0 before 2.0.11.
Users are recommended to upgrade to version 2.0.11, which fixes the issue.
