CVE-2016-9014

Django before 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3, when settings.DEBUG is True, allow remote attackers to conduct DNS rebinding attacks by leveraging failure to validate the HTTP Host header against settings.ALLOWED_HOSTS.

Django before 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3, when settings.DEBUG is True, allow remote attackers to conduct DNS rebinding attacks by leveraging failure to validate the HTTP Host header against settings.ALLOWED_HOSTS.

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. (CVE-2016-9013)

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. (CVE-2016-9014)

Marti Raudsepp discovered that Django incorrectly used a hardcoded password when running tests on an Oracle database. A remote attacker could possibly connect to the database while the tests are running and prevent the test user with the hardcoded password from being removed. (CVE-2016-9013)

Aymeric Augustin discovered that Django incorrectly validated hosts when being run with the debug setting enabled. A remote attacker could possibly use this issue to perform DNS rebinding attacks. (CVE-2016-9014)
