The version of macOS Server (formerly known as Mac OS X Server) installed on the remote host is prior to 5.2. It is, therefore, affected by the following vulnerabilities :

  - The Apache HTTP Server is affected by a     man-in-the-middle vulnerability known as 'httpoxy' due     to a failure to properly resolve namespace conflicts in     accordance with RFC 3875 section 4.1.18. The HTTP_PROXY     environment variable is set based on untrusted user data     in the 'Proxy' header of HTTP requests. The HTTP_PROXY     environment variable is used by some web client     libraries to specify a remote proxy server. An     unauthenticated, remote attacker can exploit this, via a     crafted 'Proxy' header in an HTTP request, to redirect     an application's internal HTTP traffic to an arbitrary     proxy server where it may be observed or manipulated.
    (CVE-2016-4694)

  - Multiple unspecified flaws exist that are related to     the RC4 algorithm that allow an unauthenticated, remote     attacker to defeat cryptographic protection mechanisms.
    (CVE-2016-4754)

The remote host is running a version of Mac OS X that is prior to 10.10.5, 10.11.x prior to 10.11.6, or is not macOS 10.12. It is, therefore, affected by multiple vulnerabilities in the following components :
