The remote host is missing a security update for macOS Server.
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.
- Multiple unspecified flaws exist that are related to
the RC4 algorithm that allow an unauthenticated, remote
attacker to defeat cryptographic protection mechanisms.
