Alpine: multiple grafana packages: security update to 8.3.2-r0

medium Tenable Cloud Security Plugin ID 404802

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - Grafana is an open-source platform for monitoring and observability. Grafana prior to versions 8.3.2 and
 7.5.12 contains a directory traversal vulnerability for fully lowercase or fully uppercase .md files. The
 vulnerability is limited in scope, and only allows access to files with the extension .md to authenticated
 users only. Grafana Cloud instances have not been affected by the vulnerability. Users should upgrade to
 patched versions 8.3.2 or 7.5.12. 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. Alternatively, for fully lowercase or fully uppercase .md files,
 users can block /api/plugins/.*/markdown/.* without losing any functionality beyond inlined plugin help
 text. (CVE-2021-43813)

 - 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. (CVE-2021-43815)
