"The version of Paessler PRTG Network Monitor installed on the remote host is prior to 18.2.40.1683. It is, therefore,
affected by a local file inclusion vulnerability:

  - PRTG Network Monitor before 18.2.40.1683 allows remote unauthenticated attackers to create users with read-write
    privileges (including administrator). A remote unauthenticated user can craft an HTTP request and override
    attributes of the 'include' directive in /public/login.htm and perform a Local File Inclusion attack, by including
    /api/addusers and executing it. By providing the 'id' and 'users' parameters, an unauthenticated attacker can create
    a user with read-write privileges (including administrator). (CVE-2018-19410)

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