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

  - It was found that FreeIPA 4.2.0 and later could
    disclose password hashes to users having the 'System:
    Read Stage Users' permission. A remote, authenticated
    attacker could potentially use this flaw to disclose
    the password hashes belonging to Stage Users. This
    security issue does not result in disclosure of
    password hashes belonging to active standard users.
    NOTE: some developers feel that this report is a
    suggestion for a design change to Stage User
    activation, not a statement of a
    vulnerability.(CVE-2017-12169)

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.");
