<p>On Nov. 2, during an internal security audit, we discovered that when the fine-grained access control beta feature is enabled and there is more than one organization in the Grafana instance, Grafana 8.0 introduced a mechanism which allowed users with the Organization Admin role to list, add, remove, and update users’ roles in other organizations in which they are not an admin.</p> |

<p>If an attacker is able to convince a victim to visit a URL referencing a vulnerable page, arbitrary JavaScript content may be executed within the context of the victim’s browser.</p> |
| 42 |
<p>The user visiting the malicious link must be unauthenticated, and the link must be for a page that contains the login button in the menu bar.</p> |
| 43 |
<p>There are two ways an unauthenticated user can open a page in Grafana that contains the login button:</p> |
| 44 |
<ul> |
| 45 |
<li>Anonymous authentication is enabled. This means all pages in Grafana would be open for the attack.</li> |
| 46 |
<li>The link is to an unauthenticated page. The following pages are vulnerable: |
| 47 |
<ul> |
| 48 |
<li><code>/dashboard-solo/snapshot/*</code></li> |
| 49 |
<li><code>/dashboard/snapshot/*</code></li> |
| 50 |
<li><code>/invite/:code</code></li> |
| 51 |
</ul> |
| 52 |
</li> |
| 53 |
</ul> |
| 54 |
<p>The url has to be crafted to exploit AngularJS rendering and contain the interpolation binding for AngularJS expressions. AngularJS uses double curly braces for interpolation binding: <code>{{ }}</code></p> |
| 55 |
<p>An example of an expression would be: <code>{{constructor.constructor(‘alert(1)’)()}}</code>. This can be included in the link URL like this:</p> |
| 56 |
<p><a href="https://play.grafana.org/dashboard/snapshot/%7B%7Bconstructor.constructor('alert(1)')()%7D%7D?orgId=1">https://play.grafana.org/dashboard/snapshot/%7B%7Bconstructor.constructor('alert(1)')()%7D%7D?orgId=1</a></p> |
| 57 |
<p>When the user follows the link and the page renders, the login button will contain the original link with a query parameter to force a redirect to the login page. The URL is not validated, and the AngularJS rendering engine will execute the JavaScript expression contained in the URL.</p> |
