Grafana 8.4.3 allows reading files via (for example) a /dashboard/snapshot/%7B%7Bconstructor.constructor'/.. /.. /.. /.. /.. /.. /.. /.. /etc/passwd URI. NOTE: the vendor's position is that there is no vulnerability; this request yields a benign error page, not /etc/passwd content
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
