How to fix?

Upgrade Echo:latest twisted to version 16.4.0-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream twisted package and not the twisted package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Twisted before 16.3.1 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue.
