The Apache HTTP Server in Apple OS X before 10.12 and OS X Server before
5.2 follows RFC 3875 section 4.1.18 and therefore does not protect
applications from the presence of untrusted CGI client data in the
HTTP_PROXY environment variable, which might allow remote attackers to
redirect an application’s outbound HTTP traffic to an arbitrary proxy
server via a crafted Proxy header in an HTTP request, aka an “httpoxy”
issue, a related issue to CVE-2016-5387.

Notes

Author Note
