"The CentOS Linux 7 host has a package installed that is affected by a vulnerability as referenced in the TuxCare
CENTOS7:CLSA-2024:1730142448 advisory.

  - A vulnerability in the package_index module of pypa/setuptools versions up to 69.1.1 allows for remote
    code execution via its download functions. These functions, which are used to download packages from URLs
    provided by users or retrieved from package index servers, are susceptible to code injection. If these
    functions are exposed to user-controlled inputs, such as package URLs, they can execute arbitrary commands
    on the system. The issue is fixed in version 70.0. (CVE-2024-6345)

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