This wiki page is for the description of the Expertiza based OSS project - E1957
Introduction
Background
- In Expertiza, If a user is listed as a TA in one course and as a student in another course, then if they navigate to the "Your scores" page of one of the assignments in which they are participating as a student, they can see a TA's view of that page. This would allow them to assign their own grades! However, TAs should not be able to change their grades from the course that they participated in as a student before.
- A student can upload files with their submission. In some cases, students upload long videos that might not be necessary for the submission. As there is no restriction on the files being uploaded, this is a security issue in Expertiza. Uploaded file's size and type should be restricted since a student may also upload malware into the system affecting Expertiza.
