"According to the version of the python-pip packages installed, the
EulerOS Virtualization installation on the remote host is affected by
the following vulnerability :

  - ** DISPUTED ** An issue was discovered in pip (all
    versions) because it installs the version with the
    highest version number, even if the user had intended
    to obtain a private package from a private index. This
    only affects use of the --extra-index-url option, and
    exploitation requires that the package does not already
    exist in the public index (and thus the attacker can
    put the package there with an arbitrary version
    number). NOTE: it has been reported that this is
    intended functionality and the user is responsible for
    using --extra-index-url securely.(CVE-2018-20225)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
