compute_graph (text/javascript) and the machine type, disk bus, video
model and domain capability views (text/html) return JSON; send it as
application/json. create_instance_w1.html builds the chipset <option>
elements with .val().text() instead of string concatenation.
Several views returned json.dumps() output through HttpResponse, i.e. as
text/html, and guess_mac_address reflects the URL's vname into it
(reflected XSS). Templates filled the log table and volume dropdowns by
concatenating server data into HTML strings, and log messages contain
user-entered snapshot/disk/clone names (stored XSS that runs when a
superuser opens the Logs tab).
- Use JsonResponse in guess_mac_address, random_mac_address,
guess_clone_name, sshkeys, storages.get_volumes,
datasource.os_metadata_json and logs.vm_logs; sshkeys?plain=true is
served as text/plain.
- stats_tab.html builds log rows with .text(); instance.html and
create_instance_w2.html build <option> elements with .val().text().
