"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are
affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0812-1 advisory.

  - Grafana is an open-source platform for monitoring and observability. Starting with the 8.1 branch and
    prior to versions 8.5.16, 9.2.10, and 9.3.4, Grafana had a stored XSS vulnerability affecting the core
    plugin GeoMap. The stored XSS vulnerability was possible because SVG files weren't properly sanitized and
    allowed arbitrary JavaScript to be executed in the context of the currently authorized user of the Grafana
    instance. An attacker needs to have the Editor role in order to change a panel to include either an
    external URL to a SVG-file containing JavaScript, or use the `data:` scheme to load an inline SVG-file
    containing JavaScript. This means that vertical privilege escalation is possible, where a user with Editor
    role can change to a known password for a user having Admin role if the user with Admin role executes
    malicious JavaScript viewing a dashboard. Users may upgrade to version 8.5.16, 9.2.10, or 9.3.4 to receive
    a fix. (CVE-2022-23552)

  - Grafana is an open-source platform for monitoring and observability. Prior to versions 8.5.16 and 9.2.8,
    malicious user can create a snapshot and arbitrarily choose the `originalUrl` parameter by editing the
    query, thanks to a web proxy. When another user opens the URL of the snapshot, they will be presented with
    the regular web interface delivered by the trusted Grafana server. The `Open original dashboard` button no
    longer points to the to the real original dashboard but to the attacker's injected URL. This issue is
    fixed in versions 8.5.16 and 9.2.8. (CVE-2022-39324)

  - A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient
    to cause a denial of service from a small number of small requests. (CVE-2022-41723)

  - Prometheus Exporter Toolkit is a utility package to build exporters. Prior to versions 0.7.2 and 0.8.2, if
    someone has access to a Prometheus web.yml file and users' bcrypted passwords, they can bypass security by
    poisoning the built-in authentication cache. Versions 0.7.2 and 0.8.2 contain a fix for the issue. There
    is no workaround, but attacker must have access to the hashed password to use this functionality.
    (CVE-2022-46146)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
