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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

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

Note that Nessus relies on the presence of the package as reported by the vendor.

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.
