The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4226 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)

  - In Go before 1.14.14 and 1.15.x before 1.15.7, crypto/elliptic/p224.go can generate incorrect outputs,     related to an underflow of the lowest limb during the final complete reduction in the P-224 field.
    (CVE-2021-3114)

  - Go before 1.15.13 and 1.16.x before 1.16.5 has functions for DNS lookups that do not validate replies from     DNS servers, and thus a return value may contain an unsafe injection (e.g., XSS) that does not conform to     the RFC1035 format. (CVE-2021-33195)

  - In Go before 1.15.13 and 1.16.x before 1.16.5, some configurations of ReverseProxy (from     net/http/httputil) result in a situation where an attacker is able to drop arbitrary headers.
    (CVE-2021-33197)

  - The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an     X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS     server to cause a TLS client to panic. (CVE-2021-34558)

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

The remote SUSE Linux SUSE15 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1148-1 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.

The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2021:4226 advisory.

  - golang: crypto/tls: certificate of wrong type is causing TLS client to panic (CVE-2021-34558)

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

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0073 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2020-11110:
    Grafana through 6.7.1 allows stored XSS due to insufficient input protection in the originalUrl field,     which allows an attacker to inject JavaScript code that will be executed after clicking on Open Original     Dashboard after visiting the snapshot.

    CVE-2020-12052:
    Grafana version < 6.7.3 is vulnerable for annotation popup XSS.

    CVE-2020-12245:
    Grafana before 6.7.3 allows table-panel XSS via column.title or cellLinkTooltip.

    CVE-2020-24303:
    Grafana before 7.1.0-beta 1 allows XSS via a query alias for the ElasticSearch datasource.

    CVE-2020-27846:
    A signature verification vulnerability exists in crewjam/saml. This flaw allows an attacker to bypass SAML     Authentication. The highest threat from this vulnerability is to confidentiality, integrity, as well as     system availability.

    CVE-2019-15043:
    In Grafana 2.x through 6.x before 6.3.4, parts of the HTTP API allow unauthenticated use. This makes it     possible to run a denial of service attack against the server running Grafana.

    CVE-2020-12458:
    An information-disclosure flaw was found in Grafana through 6.7.3. The database directory /var/lib/grafana     and database file /var/lib/grafana/grafana.db are world readable. This can result in exposure of sensitive     information (e.g., cleartext or encrypted datasource passwords).

    CVE-2020-12459:
    In certain Red Hat packages for Grafana 6.x through 6.3.6, the configuration files     /etc/grafana/grafana.ini and /etc/grafana/ldap.toml (which contain a secret_key and a bind_password) are     world readable.

    CVE-2020-13379:
    The avatar feature in Grafana 3.0.1 through 7.0.1 has an SSRF Incorrect Access Control issue. This     vulnerability allows any unauthenticated user/client to make Grafana send HTTP requests to any URL and     return its result to the user/client. This can be used to gain information about the network that Grafana     is running on. Furthermore, passing invalid URL objects could be used for DOS'ing Grafana via SegFault.

    CVE-2020-13430:
    Grafana before 7.0.0 allows tag value XSS via the OpenTSDB datasource.

    CVE-2021-27358:
    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-2021-39226:
    Grafana is an open source data visualization platform. In affected versions unauthenticated and     authenticated users are able to view the snapshot with the lowest database key by accessing the literal     paths: /dashboard/snapshot/:key, or /api/snapshots/:key. If the snapshot public_mode configuration     setting is set to true (vs default of false), unauthenticated users are able to delete the snapshot with     the lowest database key by accessing the literal path: /api/snapshots-delete/:deleteKey. Regardless of the     snapshot public_mode setting, authenticated users are able to delete the snapshot with the lowest     database key by accessing the literal paths: /api/snapshots/:key, or /api/snapshots-delete/:deleteKey. The     combination of deletion and viewing enables a complete walk through all snapshot data while resulting in     complete snapshot data loss. This issue has been resolved in versions 8.1.6 and 7.5.11. If for some reason     you cannot upgrade you can use a reverse proxy or similar to block access to the literal paths:
    /api/snapshots/:key, /api/snapshots-delete/:deleteKey, /dashboard/snapshot/:key, and /api/snapshots/:key.
    They have no normal function and can be disabled without side effects.
