FreeBSD : grafana -- XSS vulnerability (45eb98d6-3b13-11f0-97f7-b42e991fc52e)

high Nessus Plugin ID 237401

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 45eb98d6-3b13-11f0-97f7-b42e991fc52e advisory.

 [email protected] reports:
 A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect. This allows attackers to redirect users to a website that hosts a frontend plugin that will execute arbitrary JavaScript. This vulnerability does not require editor permissions and if anonymous access is enabled, the XSS will work. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read SSRF.

 The default Content-Security-Policy (CSP) in Grafana will block the XSS though the `connect-src` directive.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
