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

- 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.
