CVE-2020-15216
Description
From CVE.org
In goxmldsig (XML Digital Signatures implemented in pure Go) before version 1.1.0, with a carefully crafted XML file, an attacker can completely bypass signature validation and pass off an altered file as a signed one. A patch is available, all users of goxmldsig should upgrade to at least revision f6188febf0c29d7ffe26a0436212b19cb9615e64 or version 1.1.0
Statement
Whilst the OpenShift Container Platform (OCP) and OpenShift Service Mesh (OSSM) grafana container does include goxmldsig, it is only included as part of the SAML implementation. SAML is only available in the enterprise version of Grafana (https://grafana.com/docs/grafana/latest/auth/saml/). Hence the openshift4/ose-grafana and servicemesh-grafana containers have been marked as wont-fix and may be addressed in a future update.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
