"The version of SolarWinds Serv-U installed on the remote host is prior to 15.5 / 15.5. It is, therefore, affected by
multiple vulnerabilities as referenced in the serv-u_15_5 advisory.

  - SolarWinds Serv-U is vulnerable to a directory traversal vulnerability where remote code execution is
    possible depending on privileges given to the authenticated user. This issue requires a user to be
    authenticated and this is present when software environment variables are abused. Authentication is
    required for this vulnerability (CVE-2024-45711)

  - Application is vulnerable to Cross Site Scripting (XSS) an authenticated attacker with users' permissions
    can modify a variable with a payload. (CVE-2024-45714)

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