Description Kurt Seifried 2013-01-31 00:52:48 EST
*** Reported by Tomas Sedovic to the private aeolus-security mailing list ***

Tomas Sedovic discovered a security issue with Aeolus Conductor. Tested on master (e4d068b8d97906bf073dc20cbff895a10c3151e1).

An unprivileged user is able to change their Maximum Running Instances
quota on their user account page.

Steps to reproduce:
1. As an admin, create a new user "John Doe" with default permissions and quota 3
2. Logout
3. Log in as the newly created user
4. Select the "Administer" tab
5. Press the "Edit" button below Username
6. Verify that "Maximum Running Instances" quota is set to "3"
7. Change the quota to 10000
8. Press "Update User"

Expected: the quota will remain "3"
Actual: jdoe's quota is now set to "10000"

That the change is real can be verified by logging as an Admin again and going to the Users page.
