A flaw was found in the Inets application in Erlang version 22.1 and possibly earlier, where it follows RFC 3875 section 4.1.18 and does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable. This flaw allows remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request.

Description Dhananjay Arunesh 2020-04-16 09:32:46 UTC 
A vulnerability was found in inets in Erlang possibly 22.1 and earlier 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, 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.

Comment 6 Nick Tait 2020-04-20 17:27:01 UTC 
Statement:

Red Hat CloudFroms 5.10 ship affected Erlang package, however, CloudFroms uses it as a dependency for Ansible Tower and do not expose it anywhere in product. Furthermore, Ansible Tower does not pass environment variables to RabbitMQ or Erlang which makes it not affected.

Red Hat OpenStack Platform ships the affected Erlang package, however it is only used as a dependency for RabbitMQ and is not exposed outside the management network. As this network is tightly-regulated to OpenStack administrators, the risk for abuse is significantly reduced.
