"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3744 advisory.

  - In Django 2.2 before 2.2.20, 3.0 before 3.0.14, and 3.1 before 3.1.8, MultiPartParser allowed directory
    traversal via uploaded files with suitably crafted file names. Built-in upload handlers were not affected
    by this vulnerability. (CVE-2021-28658)

  - In Django 2.2 before 2.2.21, 3.1 before 3.1.9, and 3.2 before 3.2.1, MultiPartParser, UploadedFile, and
    FieldFile allowed directory traversal via uploaded files with suitably crafted file names.
    (CVE-2021-31542)

  - Django before 2.2.24, 3.x before 3.1.12, and 3.2.x before 3.2.4 has a potential directory traversal via
    django.contrib.admindocs. Staff members could use the TemplateDetailView view to check the existence of
    arbitrary files. Additionally, if (and only if) the default admindocs templates have been customized by
    application developers to also show file contents, then not only the existence but also the file contents
    would have been exposed. In other words, there is directory traversal outside of the template root
    directories. (CVE-2021-33203)

  - In Django 2.2 before 2.2.24, 3.x before 3.1.12, and 3.2 before 3.2.4, URLValidator, validate_ipv4_address,
    and validate_ipv46_address do not prohibit leading zero characters in octal literals. This may allow a
    bypass of access control that is based on IP addresses. (validate_ipv4_address and validate_ipv46_address
    are unaffected with Python 3.9.5+..) . (CVE-2021-33571)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
