AI-suggested

1. Immediate upgrade to VolkovLabs Business Links plugin version 2.4.0 or later to apply the official fix that sanitizes the URL input field. 2. Review and restrict Editor privileges within Grafana to only trusted users, minimizing the number of accounts that could exploit this vulnerability. 3. Implement strict input validation and Content Security Policy (CSP) headers at the web server or reverse proxy level to limit the execution of injected scripts. 4. Monitor Grafana logs for unusual administrative actions or privilege escalations, and enable alerting for suspicious activities. 5. Conduct regular security audits of Grafana plugins and configurations to detect outdated or vulnerable components. 6. Educate users with Editor roles about phishing and social engineering risks to reduce the likelihood of user interaction exploitation. 7. If upgrading immediately is not feasible, consider temporarily disabling the Business Links plugin or restricting access to the affected functionality until patched.

Description

The Volkov Labs Business Links panel for Grafana provides an interface to navigate using external links, internal dashboards, time pickers, and dropdown menus. Prior to version 2.4.0, a malicious actor with Editor privileges can escalate their privileges to Administrator and perform arbitrary administrative actions. This is possible because the plugin allows arbitrary JavaScript code injection in the [Layout] → [Link] → [URL] field. Version 2.4.0 contains a fix for the issue.
