What is CVE-2016-4694?
CVE-2016-4694 is a critical server-side request forgery vulnerability in Apple Mac Os X, published on 25 Sep 2016. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
