django.contrib.auth.forms.AuthenticationForm in Django 2.0 before 2.0.2, and 1.11.8 and 1.11.9, allows remote attackers to obtain potentially sensitive information by leveraging data exposure from the confirm_login_allowed() method, as demonstrated by discovering whether a user account is inactive.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - In Django 1.10.x before 1.10.8 and 1.11.x before 1.11.5, HTML autoescaping was disabled in a portion of
    the template for the technical 500 debug page. Given the right circumstances, this allowed a cross-site
    scripting attack. This vulnerability shouldn't affect most production sites since you shouldn't run with
    "DEBUG = True" (which makes this page accessible) in your production settings. (CVE-2017-12794)

    confirm_login_allowed() method, as demonstrated by discovering whether a user account is inactive.
    (CVE-2018-6188)

  - An issue was discovered in Django 2.0 before 2.0.3, 1.11 before 1.11.11, and 1.8 before 1.8.19. The
    django.utils.html.urlize() function was extremely slow to evaluate certain inputs due to catastrophic
    backtracking vulnerabilities in two regular expressions (only one regular expression for Django 1.8.x).
    The urlize() function is used to implement the urlize and urlizetrunc template filters, which were thus
    vulnerable. (CVE-2018-7536)

  - An issue was discovered in Django 2.0 before 2.0.3, 1.11 before 1.11.11, and 1.8 before 1.8.19. If
    django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were
    extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular
    expression. The chars() and words() methods are used to implement the truncatechars_html and
    truncatewords_html template filters, which were thus vulnerable. (CVE-2018-7537)

Django release notes :

CVE-2018-6188: Information leakage in AuthenticationForm

A regression in Django 1.11.8 made AuthenticationForm run its confirm_login_allowed() method even if an incorrect password is entered. This can leak information about a user, depending on what messages confirm_login_allowed() raises. If confirm_login_allowed() isn't overridden, an attacker enter an arbitrary username and see if that user has been set to is_active=False. If confirm_login_allowed() is overridden, more sensitive details could be leaked.

This issue is fixed with the caveat that AuthenticationForm can no longer raise the 'This account is inactive.' error if the authentication backend rejects inactive users (the default authentication backend, ModelBackend, has done that since Django 1.10). This issue will be revisited for Django 2.1 as a fix to address the caveat will likely be too invasive for inclusion in older versions.
