Product | Affected Versions
Grafana OSS | 11.5.0 to 11.6.2, 11.5.0 to 11.5.5, 11.5.0 to 11.4.5, 11.5.0 to 11.3.7
How the Exploit Works
The exploit takes advantage of an open redirect vulnerability in Grafana OSS, using it as a springboard to launch XSS attacks. By manipulating URLs, an attacker can redirect victims to malicious websites where XSS payloads can be delivered. Furthermore, the vulnerability can be chained with path traversal vulnerabilities, enhancing the potential impact of the XSS attack.
Conceptual Example Code
Below is a conceptual example of an HTTP request that exploits the vulnerability:
GET /redirect?url=http://malicious-site.com/xss_payload HTTP/1.1
Host: vulnerable-grafana.example.comIn this example, the GET request asks the Grafana server to redirect to a malicious URL containing the XSS payload.
Mitigation Guidance
Affected users are advised to apply the vendor patch immediately. The vulnerability has been fixed in Grafana versions 12.0.2+security-01, 11.6.3+security-01, 11.5.6+security-01, 11.4.6+security-01 and 11.3.8+security-01. As a temporary mitigation, users may also implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS).
