CVE-2016-9013: 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.
Thanks Marti Raudsepp for reporting the issue.
CVE-2016-9014: 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.
Thanks Aymeric Augustin for reporting the issue.
