Django is a high-level Python Web framework that encourages rapid development and a clean, pragmatic design. It focuses on automating as much as possible and adhering to the DRY (Don't Repeat Yourself) principle.
- An open-redirect flaw was found in the way Django's django.utils.http.is_safe_url() function filtered authentication URLs. An attacker able to trick a victim into visiting a crafted URL could use this flaw to redirect that victim to a malicious site. (CVE-2016-2512)
- A timing attack flaw was found in the way Django's PBKDF2PasswordHasher performed password hashing. Passwords hashed with an older version of PBKDF2PasswordHasher used less hashing iterations, and thus allowed an attacker to enumerate existing users based on the time differences in the login requests. (CVE-2016-2513)
Red Hat would like to thank the Django project for reporting these issues.
