It was discovered that there was a potential settings leak in date template filter of Django, a web-development framework.

If an application allows users to specify an unvalidated format for dates and passes this format to the date filter, e.g. {{ last_updated|date:user_date_format }}, then a malicious user could obtain any secret in the application’s settings by specifying a settings key instead of a date format. e.g. ‘SECRET_KEY’ instead of ‘j/m/Y’.

To remedy this, the underlying function used by the date template filter, django.utils.formats.get_format(), now only allows accessing the date/time formatting settings.

For Debian 6 Squeeze, this issue has been fixed in python-django version 1.2.3-3+squeeze15.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
