Remediation
Red Hat statement
Since the HTTP Response "Content Type" is "text/plain" most browsers won't execute any Javascipt in the response content. However if an attacker can trick a user into loading the response in an iFrame it is possible to exploit this vulnerability. Appropriate Cross Origin Resource (CORS) Allowed Domain configuration in OCP 3 should prevent an attacker from getting any response from a attacker hosted domain. Therefore make sure that corsAllowedDomains is specified correctly in your OCP 3 master-config.yaml. See [1] for more details on an issue with corsAllowedDomains in OCP 3. [1] https://bugzilla.redhat.com/show_bug.cgi?id=1694913 Also content sniffing browsers [2] do execute Javascript even when the "Content Type" HTTP Response header is set to "text/plain".
