Studio in Open edX Ironwood 2.5, when CodeJail is not used, allows a user to go to the "Create New course>New section>New subsection>New unit>Add new component>Problem button>Advanced tab>Custom Python evaluated code" screen, edit the problem, and execute Python code. This leads to arbitrary code execution.
