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

  - grafana: snapshot feature allow an unauthenticated remote attacker to trigger a DoS via a remote API call     (CVE-2021-27358)

  - golang: crypto/elliptic: incorrect operations on the P-224 curve (CVE-2021-3114)

  - golang: net: lookup functions may return invalid host names (CVE-2021-33195)

  - golang: net/http/httputil: ReverseProxy forwards connection headers if first one is empty (CVE-2021-33197)

  - 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 AlmaLinux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ALSA-2021:4226 advisory.
