Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists when the CGI Servlet is enabled, follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable. A remote attacker can 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.
