Summary

Django before 1.11.27, 2.x before 2.2.9, and 3.x before 3.0.1 allows account takeover. A suitably crafted email address (that is equal to an existing user's email address after case transformation of Unicode characters) would allow an attacker to be sent a password reset token for the matched user account. (One mitigation in the new releases is to send password reset tokens only to the registered user email address.)

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Password Recovery Exploitation
    An attacker may take advantage of the application feature to help users recover their forgotten passwords in order to gain access into the system with the same privileges as the original user. Generally password recovery schemes tend to be weak and insecure. Most of them use only one security question . For instance, mother's maiden name tends to be a fairly popular one. Unfortunately in many cases this information is not very hard to find, especially if the attacker knows the legitimate user. These generic security questions are also re-used across many applications, thus making them even more insecure. An attacker could for instance overhear a coworker talking to a bank representative at the work place and supplying their mother's maiden name for verification purposes. An attacker can then try to log in into one of the victim's accounts, click on "forgot password" and there is a good chance that the security question there will be to provide mother's maiden name. A weak password recovery scheme totally undermines the effectiveness of a strong password scheme.

    descriptionIt was discovered that there were two issues in Django, the Python web development framework : - CVE-2020-13254: Potential a data leakage via malformed memcached keys. In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage. In order to avoid this vulnerability, key validation is added to the memcached cache backends. - CVE-2020-13596: Possible XSS via admin ForeignKeyRawIdWidget. Query parameters to the admin ForeignKeyRawIdWidget were not properly URL encoded, posing an XSS attack vector. ForeignKeyRawIdWidget now ensures query parameters are correctly URL encoded. For more information, please see : https://www.djangoproject.com/weblog/2020/jun/03/security-releases/ This upload also addresses test failures introduced in 1.7.11-1+deb8u3 and 1.7.11-1+deb8u8 via the fixes for CVE-2018-7537 and CVE-2019-19844 respectfully.

"It was discovered that there was a potential account hijack
vulnerabilility in Django, the Python-based web development framework.

Django's password-reset form used a case-insensitive query to retrieve
accounts matching the email address requesting the password reset.
Because this typically involves explicit or implicit case
transformations, an attacker who knew the email address associated
with a user account could craft an email address which is distinct
from the address associated with that account, but which -- due to the
behavior of Unicode case transformations -- ceases to be distinct
after case transformation, or which will otherwise compare equal given
database case-transformation or collation behavior. In such a
situation, the attacker can receive a valid password-reset token for
the user account.

To resolve this, two changes were made in Django :

  - After retrieving a list of potentially-matching accounts
    from the database, Django's password reset functionality
    now also checks the email address for equivalence in
    Python, using the recommended identifier-comparison
    process from Unicode Technical Report 36, section
    2.11.2(B)(2).

  - When generating password-reset emails, Django now sends
    to the email address retrieved from the database, rather
    than the email address submitted in the password-reset
    request form.

For more information, please see :

https://www.djangoproject.com/weblog/2019/dec/18/security-releases/

For Debian 8 'Jessie', this issue has been fixed in python-django
version 1.7.11-1+deb8u8.

We recommend that you upgrade your python-django packages.

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."
