|
|
|
|

|
Try to HTTP request to `https://example.com/login` and there is a form login
|
|
|
|
1. Find the related CVE by checking grafana version
|
|
* How to find the grafana version
|
|
|
|
Try to request to `https://example.com/login` and then check the source code. You will find the version in JSON body `"isEnterprise":false,"latestVersion:"9.0.0","version":"8.3.2"` so 8.3.2 is the grafana version. If you found outdated grafana version, find the CVEs at [CVEDetails](https://www.cvedetails.com/vulnerability-list/vendor_id-18548/product_id-47055/Grafana-Grafana.html)
