Описание
Grafana is an open-source platform for monitoring and observability. In affected versions 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. 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. 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: {{ }} ex: {{constructor.constructor(‘alert(1)’)()}}. 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. Users are advised to upgrade as soon as possible. If for some reason you cannot upgrade, you can use a reverse proxy or similar to block access to block the literal string {{ in the path.
A cross-site scripting (XSS) vulnerability in grafana allows an attacker to execute arbitrary JavaScript code in the browser of a victim user. An attacker may send a link referencing a page where the victim is unauthenticated and contains the login button and including interpolation binding expressions (e.g. {{ and }} in AngularJS) in the URL.
Отчет
This issue did not affect the versions of grafana as shipped with Red Hat Enterprise Linux 8 as they provide an older version that does not include the vulnerability.
