VUL-1: CVE-2021-43815: grafana: directory traversal for .csv files
Last modified: 2021-12-13 15:37:50 UTC
Grafana is an open-source platform for monitoring and observability. Grafana
prior to versions 8.3.2 and 7.5.12 has a directory traversal for arbitrary .csv
files. It only affects instances that have the developer testing tool called
TestData DB data source enabled and configured. The vulnerability is limited in
scope, and only allows access to files with the extension .csv to authenticated
users only. Grafana Cloud instances have not been affected by the vulnerability.
Versions 8.3.2 and 7.5.12 contain a patch for this issue. There is a workaround
available for users who cannot upgrade. Running a reverse proxy in front of
Grafana that normalizes the PATH of the request will mitigate the vulnerability.
The proxy will have to also be able to handle url encoded paths.
This vulnerability was originally split-off from CVE-2021-43813.
As per the upstream advisory , this only affects grafana >= 8.0.0-beta3, which I verified. Closing the issue, since we only ship older versions.
