- A booting VM is named by its address's reverse DNS entry. Without one,
the address itself was taken as the name, so its first number ("10",
"192") named the VM: a user who made a VM with that name had their keys
given to every such VM. Such an address now gets no keys; its metadata
hostname is still the address.
- Keys are written as quoted YAML strings, so a comment with an apostrophe
or ": " no longer breaks the key or the file.
131 test modules sat next to the code they test; instances alone had
51 of them beside views.py and utils.py. They move into a
tests/ package per app, and the JavaScript checks into
webvirtcloud/tests/js. Each non-empty tests.py becomes tests/test_views.py;
the empty generated stubs are removed.
Imports of the app's own modules become absolute, paths built from
__file__ go one level up, the live helper is instances.tests.livetest,
and coverage omits */tests/*. The suite discovers the same 960 tests as
before.
Nothing limited failed logins: a password could be guessed at the speed
the server answers. django-axes (8.3.1, Django 5.2, Python 3.10-3.13)
now counts them.
- A user is locked for the address the failed logins come from
(username and IP together), so an attacker cannot lock someone out
from elsewhere and users behind one NAT address do not share a lock.
A successful login resets the count. axes sits in front of every
authentication: the login page with or without OTP, LDAP and the API.
- The number of failed logins (default 5) and the lock time in minutes
(default 15) are on the Settings page (LOGIN_FAILURE_LIMIT,
LOGIN_LOCKOUT_MINUTES, added by migration appsettings.0014) and apply
at once; an invalid value falls back to the default. Unlock with
"manage.py axes_reset_username <username>".
- Behind the bundled nginx every request comes from 127.0.0.1; the
client address is read from X-Real-IP, which nginx sets, but only for
requests from a loopback address or from LOGIN_TRUSTED_PROXIES, so a
forged header does not escape a lock.
settings.py.template gets the app, middleware, backend and AXES_*
settings; README tells existing installations what to copy. Tests that
call client.login now pass a request, which the axes backend needs.
The new tests fail with axes disabled.
The OpenStack-style cloud-init endpoints (index, meta_data.json,
user_data) are fetched by booting VMs, which do not log in. Since the
login-required middleware they redirected to the login page, so the
datasource has not worked. They are login_not_required now; they expose
a hostname and the public SSH keys of a VM's owners.
A VM is found by the reverse DNS name of the client address, and VM
names are not unique (only compute and UUID are). user_data merged the
owners of every VM with that name, so a user who named their VM like
another user's VM got their key into that VM at its next cloud-init
run. Keys are now given only when exactly one VM has the name.
The client address is the last X-Forwarded-For entry, which nginx in
the default setup appends; gunicorn listens on 127.0.0.1 only. The bare
except around the reverse lookup is narrowed to OSError.
Instance.proxy looked the domain up by its stored name. After a rename
or a name swap outside WebVirtCloud, an operation on one VM changed
another; after a VM was replaced under the same name, operations hit
the new VM.
wvmInstance takes the UUID and uses lookupByUUIDString, with no
fallback to the name: a missing UUID fails instead of picking another
domain. Every caller that has an Instance passes it: proxy, console,
quota, post-migration autostart and the VDI URL. Migration uses the
domain the proxy already resolved. getvvfile and the gstfsd requests
use the host's current name of that UUID.
Live tests cover a name swap and a VM replaced under the same name;
both fail on the previous code.
Super-linter ran from the unpinned :latest image and, because of
branches-ignore: [master], never on pull requests to master. Ruff now
checks syntax errors and pyflakes rules (E9, F) on every push and PR.
Fixes the existing findings: unused imports and variables, an unused
duplicate import in instances/tests.py, and the star import in
accounts/views.py. settings-dev.py keeps its star import of the base
settings.
Add webvirtcloud/test_authorization_matrix.py, which walks every named URL
and checks that a user without any VM/compute relation only reaches an
explicit allowlist, and that the global view_instances permission does not
open consoles. It found:
- /computes/<id>/... views without any check (compute_graph,
get_compute_*, get_dom_capabilities, storages.get_volumes): the whole
computes URL namespace is now wrapped with superuser_only, so a view
added there later cannot be exposed by a missing decorator.
- guess_mac_address (leaks dhcpd.conf host/MAC pairs), random_mac_address
and guess_clone_name: superuser-only, like the buttons that use them.
- check_instance: cross-tenant VM name lookup with no caller; removed.
- getvvfile and get_vdi_url: reachable with only view_instances, and the
.vv file contains the VNC password.
Console access now follows one rule, instances.utils.can_open_console:
an active superuser or an active owner of the VM. The global
view_instances permission is read-only. It is used by the console page,
novncd, getvvfile and get_vdi_url (getvvfile and the VDI tab are kept for
virt-viewer users). The console page answers 403 instead of 500 when
access is denied, with the same answer for a missing VM.
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().
