"The version of Rejetto HTTP File Server installed on the remote host is 2.x up to 2.3m. It is, therefore, affected by a
vulnerability:

  - Rejetto HTTP File Server, up to and including version 2.3m, is vulnerable to a template injection
    vulnerability. This vulnerability allows a remote, unauthenticated attacker to execute arbitrary commands
    on the affected system by sending a specially crafted HTTP request. As of the CVE assignment date, Rejetto
    HFS 2.3m is no longer supported. (CVE-2024-23692)

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