## XSS ([CVE-2022-21702](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-21702))
### Summary
On Jan. 16, an external security researcher, Jasu Viding contacted Grafana to disclose an XSS vulnerability in the way that Grafana handles data sources.
An attacker could serve HTML content through the Grafana datasource or plugin proxy and trick a user to visit this HTML page using a specially crafted link and execute a Cross-site Scripting (XSS) attack. The attacker could either compromise an existing datasource for a specific Grafana instance or either set up its own public service and instruct anyone to set it up in their Grafana instance.
We believe that this vulnerability is rated at CVSS 6.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N).
### Impact
Should an existing data source connected to Grafana be compromised, it could be used to inappropriately gain access to other data sources connected to the same Grafana org.
### Affected versions with MEDIUM severity
To be impacted, all of the following must be applicable:
**For data source proxy**:
- A Grafana instance running version v2.0.0-beta1 up to v8.3.4.
- A Grafana HTTP-based datasource configured with Server as Access Mode and a URL set.
- Attacker to be in control of the HTTP server serving the URL of above data source.
- A specially crafted link pointing at http://host/api/datasources/proxy/"data source id" and attacker somehow tricks a user of the above Grafana instance to click/visit the link.
- A user that’s already authenticated to above Grafana instance clicks on/visits the specially crafted link sent/provided by the attacker.
**For plugin proxy**:
- A Grafana instance running version v2.0.0-beta1 up to v8.3.4.
- A Grafana HTTP-based app plugin configured and enabled with a URL set.
- Attacker to be in control of the HTTP server serving the URL of above app.
- A specially crafted link pointing at http://host/api/plugin-proxy/"plugin id" and attacker somehow tricks a user of the above Grafana instance to click/visit the link.
- A user that’s already authenticated to above Grafana instance clicks on/visits the specially crafted link sent/provided by the attacker.
**Backend plugin resource**:
- A Grafana instance running version v7.0.0-beta1 up to v8.3.4.
- Attacker potentially needs to craft a custom plugin to be able to pull this off, but if an attacker can compromise/control the backend service that a backend plugin connects to, it might be possible to serve HTML content via the /api/plugins/"plugin Id"/resources* or /api/datasources/"id"/resources* routes.
- A specially crafted link pointing at /api/plugins/"plugin Id">/resources* or /api/datasources/"id"/resources* and attacker somehow tricks a user of the above Grafana instance to click/visit the link.
- A user that’s already authenticated to above Grafana instance clicks on/visits the specially crafted link sent/provided by the attacker.
### Root Causes
#### Trigger
Reproduced and confirmed via this Golang app:
```
package main
import (
"fmt"
"log"
"net/http"
)
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "<html><body><script>alert('XSS');</script></body></html>")
})
log.Fatal(http.ListenAndServe(":3011", nil))
}
```
A Prometheus datasource is configured in Grafana with URL http://localhost:3011.
When visitining http://localhost:3000/api/datasources/proxy/170 the scripts declared in the HTML page executes. Confirmed in both Chrome and Firefox.
### Solutions and mitigations
All installations between Grafana v2.0.0-beta1 up to v8.3.4 should be upgraded as soon as possible.
#### Workarounds
Using a proxy, set a response header Content Security Policy: sandbox for the following routes:
`/api/datasources/proxy*`
`/api/plugin-proxy*`
`/api/plugins/<pluginId>/resources*`
`/api/datasources/<id>/resources*`
Another possible mitigation is setting the response header Content-Disposition: attachment; “proxy.txt”. Confirmed in both Chrome and Firefox.

## CSRF ([CVE-2022-21703](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-21703))
### Summary
On Jan. 18, security researchers [jub0bs](https://twitter.com/jub0bs) and [abrahack](https://twitter.com/theabrahack) contacted Grafana to disclose a CSRF vulnerability which allows anonymous attackers to elevate their privileges by mounting cross-origin attacks against authenticated high-privilege Grafana users (for example, Editors or Admins).
We believe that this vulnerability is rated at CVSS 6.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N).
### Impact
An attacker can exploit this vulnerability for privilege escalation by tricking an authenticated user into inviting the attacker as a new user with high privileges.
### Affected versions with MEDIUM severity
All Grafana >=3.0-beta1 versions are affected by this vulnerability.
### Solutions and mitigations
All installations after Grafana v3.0-beta1 should be upgraded as soon as possible.
Note that if you are running Grafana behind any reverse proxy, you need to make sure that you are passing the original Host and Origin headers from the client request to Grafana.
In the case of Apache Server, you need to add `ProxyPreserveHost on` in your proxy [configuration](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html). In case of NGINX, you can need to add `proxy_set_header Host $http_host;` in your [configuration](http://nginx.org/en/docs/http/ngx_http_proxy_module.html).
Appropriate patches have been applied to [Grafana Cloud](https://grafana.com/cloud) and as always, we closely coordinated with all cloud providers licensed to offer Grafana Pro. They have received early notification under embargo and confirmed that their offerings are secure at the time of this announcement. This is applicable to Amazon Managed Grafana.

## Teams API IDOR([CVE-2022-21713](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-21713))
On Jan. 18, an external security researcher, Kürşad ALSAN from [NSPECT.IO](https://www.nspect.io) ([@nspectio](https://twitter.com/nspectio) on Twitter), contacted Grafana to disclose an IDOR (Insecure Direct Object Reference) vulnerability on Grafana Teams APIs.
We believe that this vulnerability is rated at CVSS 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N).
### Impact
This vulnerability only impacts the following API endpoints:
- `/teams/:teamId` - an authenticated attacker can view unintended data by querying for the specific team ID.
- `/teams/:search` - an authenticated attacker can search for teams and see the total number of available teams, including for those teams that the user does not have access to.
- `/teams/:teamId/members` - when editors_can_admin flag is enabled, an authenticated attacker can see unintended data by querying for the specific team ID.
### Affected versions with MEDIUM severity
All Grafana >=5.0.0-beta1 versions are affected by this vulnerability.
### Solutions and mitigations
All installations after Grafana v5.0.0-beta1 should be upgraded as soon as possible.
Appropriate patches have been applied to [Grafana Cloud](https://grafana.com/cloud) and as always, we closely coordinated with all cloud providers licensed to offer Grafana Pro. They have received early notification under embargo and confirmed that their offerings are secure at the time of this announcement. This is applicable to Amazon Managed Grafana.
