"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3164 advisory.

  - An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python
    3.7+ is used). FILE_UPLOAD_DIRECTORY_PERMISSIONS mode was not applied to intermediate-level directories
    created in the process of uploading files. It was also not applied to intermediate-level collected static
    directories when using the collectstatic management command. (CVE-2020-24583)

  - An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python
    3.7+ is used). The intermediate-level directories of the filesystem cache had the system's standard umask
    rather than 0o077. (CVE-2020-24584)

  - The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before
    3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and
    urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query
    parameters using a semicolon (;), they can cause a difference in the interpretation of the request between
    the proxy (running with default configuration) and the server. This can result in malicious requests being
    cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and
    therefore would not include it in a cache key of an unkeyed parameter. (CVE-2021-23336)

  - In Django 2.2 before 2.2.18, 3.0 before 3.0.12, and 3.1 before 3.1.6, the django.utils.archive.extract
    method (used by startapp --template and startproject --template) allows directory traversal via an
    archive with absolute paths or relative paths with dot segments. (CVE-2021-3281)

  - An issue was discovered in Django 3.2 before 3.2.14 and 4.0 before 4.0.6. The Trunc() and Extract()
    database functions are subject to SQL injection if untrusted data is used as a kind/lookup_name value.
    Applications that constrain the lookup name and kind choice to a known safe list are unaffected.
    (CVE-2022-34265)

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