|
|

|
info:
|
|
name: Grafana 8.0.0 <= v.8.2.2 - Angularjs Rendering Cross-Site Scripting
|
|
author: pdteam
|
|
severity: medium
|
|
description: 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.
|
|
remediation: Upgrade to 8.2.3 or higher.
