More information:

Several vulnerabilities were discovered in Django, a high-level Python web development framework. The Common Vulnerabilities and Exposures project identifies the following problems:

  • CVE-2014-0472

    Benjamin Bach discovered that Django incorrectly handled dotted Python paths when using the reverse() URL resolver function. An attacker able to request a specially crafted view from a Django application could use this issue to cause Django to import arbitrary modules from the Python path, resulting in possible code execution.

  • CVE-2014-0473

    Paul McMillan discovered that Django incorrectly cached certain pages that contained CSRF cookies. A remote attacker could use this flaw to acquire the CSRF token of a different user and bypass intended CSRF protections in a Django application.

  • CVE-2014-0474

    Michael Koziarski discovered that certain Django model field classes did not properly perform type conversion on their arguments, which allows remote attackers to obtain unexpected results.

  • CVE-2014-1418

    Michael Nelson, Natalia Bidart and James Westby discovered that cached data in Django could be served to a different session, or to a user with no session at all. An attacker may use this to retrieve private data or poison caches.

  • CVE-2014-3730

    Peter Kuma and Gavin Wahl discovered that Django incorrectly validated certain malformed URLs from user input. An attacker may use this to cause unexpected redirects.
