Django 1.10.3 修复了 1.10.2 中的两个安全问题和几个漏洞。

User with hardcoded password created when running tests on Oracle

When running tests with an Oracle database, Django creates a temporary database user. In older versions, if a password isn't manually specified in the database settings TEST dictionary, a hardcoded password is used. This could allow an attacker with network access to the database server to connect.

This user is usually dropped after the test suite completes, but not when using the manage.py test --keepdb option or if the user has an active session (such as an attacker's connection).

A randomly generated password is now used for each test run.

DNS rebinding vulnerability when DEBUG=True

Older versions of Django don't validate the Host header against settings.ALLOWED_HOSTS when settings.DEBUG=True. This makes them vulnerable to a DNS rebinding attack.

While Django doesn't ship a module that allows remote code execution, this is at least a cross-site scripting vector, which could be quite serious if developers load a copy of the production database in development or connect to some production services for which there's no development instance, for example. If a project uses a package like the django-debug-toolbar, then the attacker could execute arbitrary SQL, which could be especially bad if the developers connect to the database with a superuser account.

settings.ALLOWED_HOSTS is now validated regardless of DEBUG. For convenience, if ALLOWED_HOSTS is empty and DEBUG=True, the following variations of localhost are allowed ['localhost', '127.0.0.1', '::1']. If your local settings file has your production ALLOWED_HOSTS value, you must now omit it to get those fallback values.

漏洞修复

  • Allowed User.is_authenticated and User.is_anonymous properties to be tested for set membership (#27309).
  • Fixed a performance regression when running migrate in projects with RenameModel operations (#27279).
  • Added model_name to the allow_migrate() calls in makemigrations (#27200).
  • Made the JavaScriptCatalog view respect the packages argument; previously it was ignored (#27374).
  • Fixed QuerySet.bulk_create() on PostgreSQL when the number of objects is a multiple plus one of batch_size (#27385).
  • Prevented i18n_patterns() from using too much of the URL as the language to fix a use case for prefix_default_language=False (#27063).
  • Replaced a possibly incorrect redirect from SessionMiddleware when a session is destroyed in a concurrent request with a SuspiciousOperation to indicate that the request can't be completed (#27363).
