Description
Summary
The pyload application does not properly invalidate or modify sessions upon changes made to a user's permissions.
Details
Whenever an administrator changes the permissions a specific account has, they do not expect that account still being able to access data that their new permissions do not allow. This is not the case for the pyload application, as a user with a valid session can still perform the actions.
PoC
Take a user with all the permissions, as shown below.
We now log in as this user.
Let us now take away all the permissions.
The logged in session can still be used to access everything in the application.
Impact
Should permissions be taken away, then the user is expected not to be able to execute the actions belonging to those actions anymore.
