Description
This security bulletin contains information about 1 security vulnerability.
1) Cross-site scripting (CVE-ID: CVE-2018-9090)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.
Remediation
Install update from vendor's website.
