CVE-2021-43815 (GCVE-0-2021-43815)

Vulnerability from cvelistv5 – Published: 2021-12-10 20:40 – Updated: 2024-08-04 04:03

Title

Grafana directory traversal for `.cvs` files

Summary

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.

Severity

4.3 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
