The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2023-3591 advisory.

  • An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting methods by supplying a URL that starts with blank characters. (CVE-2023-24329)

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