CVE-2018-9090: Red Hat Tectonic

Medium severity, CVSS 6.1. EPSS: 0.8% chance of exploitation in the next 30 days.

CoreOS Tectonic 1.7.x and 1.8.x before 1.8.7-tectonic.2 deploys the Grafana web application using default credentials (admin/admin) for the administrator account located at grafana-credentials secret. This occurs because CoreOS does not randomize the administrative password to later be configured by Tectonic administrators. An attacker can insert an XSS payload into the dashboards.

Affected products

• Red Hat Tectonic: from 1.7.1-tectonic.1, before 1.8.7-tectonic.2 (fixed in 1.8.7-tectonic.2)
