Description

Paul McMillan, Mozilla and the Django core team discovered several vulnerabilities in Django, a Python web framework :

  • CVE-2011-4136 When using memory-based sessions and caching, Django sessions are stored directly in the root namespace of the cache. When user data is stored in the same cache, a remote user may take over a session.

  • CVE-2011-4137, CVE-2011-4138 Django

"Paul McMillan, Mozilla and the Django core team discovered several
vulnerabilities in Django, a Python web framework :

  - CVE-2011-4136
    When using memory-based sessions and caching, Django
    sessions are stored directly in the root namespace of
    the cache. When user data is stored in the same cache, a
    remote user may take over a session.

  - CVE-2011-4137, CVE-2011-4138
    Django's field type URLfield by default checks supplied
    URL's by issuing a request to it, which doesn't time
    out. A Denial of Service is possible by supplying
    specially prepared URL's that keep the connection open
    indefinately or fill the Django's server memory.

  - CVE-2011-4139
    Django used X-Forwarded-Host headers to construct full
    URL's. This header may not contain trusted input and
    could be used to poison the cache.

  - CVE-2011-4140
    The CSRF protection mechanism in Django does not
    properly handle web-server configurations supporting
    arbitrary HTTP Host headers, which allows remote
    attackers to trigger unauthenticated forged requests."
