"The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3329
advisory.

  - An issue was discovered in the Multipart Request Parser in Django 3.2 before 3.2.18, 4.0 before 4.0.10,
    and 4.1 before 4.1.7. Passing certain inputs (e.g., an excessive number of parts) to multipart forms could
    result in too many open files or memory exhaustion, and provided a potential vector for a denial-of-
    service attack. (CVE-2023-24580)

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