"The version of Apache httpd installed on the remote host is prior to 2.4.54. It is, therefore, affected by an 
authentication bypass vulnerability as referenced in the 2.4.54 advisory.

  - X-Forwarded-For dropped by hop-by-hop mechanism in mod_proxy: Apache HTTP Server 2.4.53 and earlier may not
    send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop
    mechanism. This may be used to bypass IP based authentication on the origin server/application.
    Acknowledgements: The Apache HTTP Server project would like to thank Gaetan Ferry (Synacktiv) for
    reporting this issue 

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