CVE-2023-0594
Description
A flaw was found in the grafana package. This flaw allows a malicious user with the ability to introduce trace data to provide a JavaScript that changes the password for the user viewing the trace view (this could be an admin) to a known password, thus gaining access to the admin account.
Statement
This is an issue with Grafana Tempo which we don't ship in Red Hat Enterprise Linux. Hence, RHEL-8, 9 are not-affected.
Mitigation
Applying the Content-Security-Policy shipped with Grafana would block inline scripts from executing and would mitigate this.
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).
