CVE-2020-12666
Description
A flaw was found in macaron. Path URLs aren't cleaned before being redirected creating an open redirect in the static handler.
Statement
This issue has a low impact on both OpenShift Container Platform and OpenShift Service Mesh grafana containers. As neither components make use of the Static handler the impact is Low. A future version of Grafana may use the Macaron Static handler so we may fix this in a future release.
Red Hat Ceph Storage (RHCS) versions 3 and 4 use Grafana where the affected version of the macaron package is delivered. However the Static handler is not used by Ceph hence the impact by this vulnerability is Low. Ceph-2 has reached End of Extended Life Cycle Support and no longer fixing moderates/lows.
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).
