"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3177 advisory.

  - An issue was discovered in Django 2.2 before 2.2.26, 3.2 before 3.2.11, and 4.0 before 4.0.1.
    UserAttributeSimilarityValidator incurred significant overhead in evaluating a submitted password that was
    artificially large in relation to the comparison values. In a situation where access to user registration
    was unrestricted, this provided a potential vector for a denial-of-service attack. (CVE-2021-45115)

  - An issue was discovered in Django 2.2 before 2.2.26, 3.2 before 3.2.11, and 4.0 before 4.0.1. Due to
    leveraging the Django Template Language's variable resolution logic, the dictsort template filter was
    potentially vulnerable to information disclosure, or an unintended method call, if passed a suitably
    crafted key. (CVE-2021-45116)

  - An issue was discovered in Django 2.2 before 2.2.28, 3.2 before 3.2.13, and 4.0 before 4.0.4.
    QuerySet.annotate(), aggregate(), and extra() methods are subject to SQL injection in column aliases via a
    crafted dictionary (with dictionary expansion) as the passed **kwargs. (CVE-2022-28346)

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