The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in "view.html" because of "showErrorMessage" in "js/graph.js". A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
Example:
/view.html?q={"metrics":[{"tags":{},"name":"123","group_by":[{"name":"tag","tags":["1"]}],"aggregators":[{"name":"sum","sampling":{"value":"<script>alert(document.domain)</script>","unit":"milliseconds"}}],"limit":"1"}],"plugins":[],"cache_time":0,"start_absolute":1570723200000,"end_absolute":1571241600000}&d=[{"scale":true}]Remediation
