CVE-2018-20060

Description

From CVE.org

urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the Authorization header to be exposed to unintended hosts or transmitted in cleartext.

Statement

Red Hat Satellite 6.2 is on Maintenance Support 2 phase, hence only selected critical and important issues will be fixed. Please refer to Red Hat Satellite Product Life Cycle page for more information.

In Red Hat OpenStack Platform 13, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP python-urllib3 package.

Mitigation

Use `retries=urllib3.Retry(redirect=0)` when performing requests if you do not need redirection and handle the redirects manually if you need them.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
