"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0574 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-42005:
    An issue was discovered in Django 5.0 before 5.0.8 and 4.2 before 4.2.15. QuerySet.values() and
    values_list() methods on models with a JSONField are subject to SQL injection in column aliases via a
    crafted JSON object key as a passed *arg.

    CVE-2024-41991:
    An issue was discovered in Django 5.0 before 5.0.8 and 4.2 before 4.2.15. The urlize and urlizetrunc
    template filters, and the AdminURLFieldWidget widget, are subject to a potential denial-of-service attack
    via certain inputs with a very large number of Unicode characters.

    CVE-2024-41990:
    An issue was discovered in Django 5.0 before 5.0.8 and 4.2 before 4.2.15. The urlize() and urlizetrunc()
    template filters are subject to a potential denial-of-service attack via very large inputs with a specific
    sequence of characters.

    CVE-2024-41989:
    An issue was discovered in Django 5.0 before 5.0.8 and 4.2 before 4.2.15. The floatformat template filter
    is subject to significant memory consumption when given a string representation of a number in scientific
    notation with a large exponent.

    CVE-2024-39614:
    An issue was discovered in Django 5.0 before 5.0.7 and 4.2 before 4.2.14. get_supported_language_variant()
    was subject to a potential denial-of-service attack when used with very long strings containing specific
    characters.

    CVE-2024-39330:
    An issue was discovered in Django 5.0 before 5.0.7 and 4.2 before 4.2.14. Derived classes of the
    django.core.files.storage.Storage base class, when they override generate_filename() without replicating
    the file-path validations from the parent class, potentially allow directory traversal via certain inputs
    during a save() call. (Built-in Storage sub-classes are unaffected.)

    CVE-2024-39329:
    An issue was discovered in Django 5.0 before 5.0.7 and 4.2 before 4.2.14. The
    django.contrib.auth.backends.ModelBackend.authenticate() method allows remote attackers to enumerate users
    via a timing attack involving login requests for users with an unusable password.

    CVE-2024-38875:
    An issue was discovered in Django 4.2 before 4.2.14 and 5.0 before 5.0.7. urlize and urlizetrunc were
    subject to a potential denial of service attack via certain inputs with a very large number of brackets.

    CVE-2022-28347:
    A SQL injection issue was discovered in QuerySet.explain() in Django 2.2 before 2.2.28, 3.2 before 3.2.13,
    and 4.0 before 4.0.4. This occurs by passing a crafted dictionary (with dictionary expansion) as the
    **options argument, and placing the injection payload in an option name.

    CVE-2022-28346:
    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-2021-33203:
    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-2021-32052:
    In Django 2.2 before 2.2.22, 3.1 before 3.1.10, and 3.2 before 3.2.2 (with Python 3.9.5+), URLValidator
    does not prohibit newlines and tabs (unless the URLField form field is used). If an application uses
    values with newlines in an HTTP response, header injection can occur. Django itself is unaffected because
    HttpResponse prohibits newlines in HTTP headers.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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