Description Pedro Sampaio 2018-05-25 15:51:50 EDT

Incorrect caching of responses to requests including an Authorization header in HAProxy 1.8.0 through 1.8.9 (if cache enabled) allows attackers to achieve information disclosure via an unauthenticated remote request, related to the proto_http.c check_request_for_cacheability function.

Upstream patch:

Comment 4 Scott Gayou 2018-05-31 12:25:13 EDT

Statement:

Red Hat Product Security has rated this issue as having a security impact of Moderate, and a future update may address this flaw.

Comment 8 Jason Shepherd 2018-06-03 23:54:14 EDT

Openshift Container Platform does not make use of cache features available in HAProxy. See the upstream haproxy configuration template here:
