"The remote SUSE Linux SUSE15 host has a package installed that is affected by multiple vulnerabilities as referenced in
the openSUSE-SU-2021:2662-1 advisory.

  - The snapshot feature in Grafana 6.7.3 through 7.4.1 can allow an unauthenticated remote attackers to
    trigger a Denial of Service via a remote API call if a commonly used configuration is set.
    (CVE-2021-27358)

  - Grafana Enterprise 7.2.x and 7.3.x before 7.3.10 and 7.4.x before 7.4.5 allows a dashboard editor to
    bypass a permission check concerning a data source they should not be able to access. (CVE-2021-27962)

  - The team sync HTTP API in Grafana Enterprise 7.4.x before 7.4.5 has an Incorrect Access Control issue. On
    Grafana instances using an external authentication service, this vulnerability allows any authenticated
    user to add external groups to existing teams. This can be used to grant a user team permissions that the
    user isn't supposed to have. (CVE-2021-28146)

  - The team sync HTTP API in Grafana Enterprise 6.x before 6.7.6, 7.x before 7.3.10, and 7.4.x before 7.4.5
    has an Incorrect Access Control issue. On Grafana instances using an external authentication service and
    having the EditorsCanAdmin feature enabled, this vulnerability allows any authenticated user to add
    external groups to any existing team. This can be used to grant a user team permissions that the user
    isn't supposed to have. (CVE-2021-28147)

  - One of the usage insights HTTP API endpoints in Grafana Enterprise 6.x before 6.7.6, 7.x before 7.3.10,
    and 7.4.x before 7.4.5 is accessible without any authentication. This allows any unauthenticated user to
    send an unlimited number of requests to the endpoint, leading to a denial of service (DoS) attack against
    a Grafana Enterprise instance. (CVE-2021-28148)

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