erlang: allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy serve

Published Dec 10, 2019

Description

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.

Affected products

Remediation

Red Hat 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.
