Grafana is an open-source platform for monitoring and observability. In Grafana Enterprise, the Request security feature allows list allows to configure Grafana in a way so that the instance doesn’t call or only calls specific hosts. The vulnerability present starting with version 7.4.0-beta1 and prior to versions 7.5.16 and 8.5.3 allows someone to bypass these security configurations if a malicious datasource (running on an allowed host) returns an HTTP redirect to a forbidden host. The vulnerability only impacts Grafana Enterprise when the Request security allow list is used and there is a possibility to add a custom datasource to Grafana which returns HTTP redirects. In this scenario, Grafana would blindly follow the redirects and potentially give secure information to the clients. Grafana Cloud is not impacted by this vulnerability. Versions 7.5.16 and 8.5.3 contain a patch for this issue. There are currently no known workarounds.

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4437-1 advisory.

  - ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before     1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon     crash. This occurs because a return value is not properly managed in a certain situation. (CVE-2021-36222)

  - In order to decrypt SM2 encrypted data an application is expected to call the API function     EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the     out parameter can be NULL and, on exit, the outlen parameter is populated with the buffer size     required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer     and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the out parameter. A bug     in the implementation of the SM2 decryption code means that the calculation of the buffer size required to     hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size     required by the second call. This can lead to a buffer overflow when EVP_PKEY_decrypt() is called by the     application a second time with a buffer that is too small. A malicious attacker who is able present SM2     content for decryption to an application could cause attacker chosen data to overflow the buffer by up to     a maximum of 62 bytes altering the contents of other data held after the buffer, possibly changing     application behaviour or causing the application to crash. The location of the buffer is application     dependent but is typically heap allocated. Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k).
    (CVE-2021-3711)

  - Grafana is an open-source platform for monitoring and observability. In affected versions if an attacker     is able to convince a victim to visit a URL referencing a vulnerable page, arbitrary JavaScript content     may be executed within the context of the victim's browser. The user visiting the malicious link must be     unauthenticated and the link must be for a page that contains the login button in the menu bar. The url     has to be crafted to exploit AngularJS rendering and contain the interpolation binding for AngularJS     expressions. AngularJS uses double curly braces for interpolation binding: {{ }} ex:
    {{constructor.constructor(alert(1)')()}}. When the user follows the link and the page renders, the login     button will contain the original link with a query parameter to force a redirect to the login page. The     URL is not validated and the AngularJS rendering engine will execute the JavaScript expression contained     in the URL. Users are advised to upgrade as soon as possible. If for some reason you cannot upgrade, you     can use a reverse proxy or similar to block access to block the literal string {{ in the path.
    (CVE-2021-41174)

  - Grafana is an open-source platform for monitoring and observability. In affected versions when the fine-     grained access control beta feature is enabled and there is more than one organization in the Grafana     instance admins are able to access users from other organizations. Grafana 8.0 introduced a mechanism     which allowed users with the Organization Admin role to list, add, remove, and update users' roles in     other organizations in which they are not an admin. With fine-grained access control enabled, organization     admins can list, add, remove and update users' roles in another organization, where they do not have     organization admin role. All installations between v8.0 and v8.2.3 that have fine-grained access control     beta enabled and more than one organization should be upgraded as soon as possible. If you cannot upgrade,     you should turn off the fine-grained access control using a feature flag. (CVE-2021-41244)

  - Grafana is an open-source platform for monitoring and observability. Grafana versions 8.0.0-beta1 through     8.3.0 (except for patched versions) iss vulnerable to directory traversal, allowing access to local files.
    The vulnerable URL path is: `<grafana_host_url>/public/plugins//`, where is the plugin ID for any     installed plugin. At no time has Grafana Cloud been vulnerable. Users are advised to upgrade to patched     versions 8.0.7, 8.1.8, 8.2.7, or 8.3.1. The GitHub Security Advisory contains more information about     vulnerable URL paths, mitigation, and the disclosure timeline. (CVE-2021-43798)

  - Grafana is an open-source platform for monitoring and observability. Grafana prior to versions 8.3.2 and     7.5.12 contains a directory traversal vulnerability for fully lowercase or fully uppercase .md files. The     vulnerability is limited in scope, and only allows access to files with the extension .md to authenticated     users only. Grafana Cloud instances have not been affected by the vulnerability. Users should upgrade to     patched versions 8.3.2 or 7.5.12. For users who cannot upgrade, running a reverse proxy in front of     Grafana that normalizes the PATH of the request will mitigate the vulnerability. The proxy will have to     also be able to handle url encoded paths. Alternatively, for fully lowercase or fully uppercase .md files,     users can block /api/plugins/.*/markdown/.* without losing any functionality beyond inlined plugin help     text. (CVE-2021-43813)

  - Grafana is an open-source platform for monitoring and observability. Grafana prior to versions 8.3.2 and     7.5.12 has a directory traversal for arbitrary .csv files. It only affects instances that have the     developer testing tool called TestData DB data source enabled and configured. The vulnerability is limited     in scope, and only allows access to files with the extension .csv to authenticated users only. Grafana     Cloud instances have not been affected by the vulnerability. Versions 8.3.2 and 7.5.12 contain a patch for     this issue. There is a workaround available for users who cannot upgrade. Running a reverse proxy in front     of Grafana that normalizes the PATH of the request will mitigate the vulnerability. The proxy will have to     also be able to handle url encoded paths. (CVE-2021-43815)

  - Grafana is an open-source platform for monitoring and observability. Versions on the 8.x and 9.x branch     prior to 9.0.3, 8.5.9, 8.4.10, and 8.3.10 are vulnerable to stored cross-site scripting via the Unified     Alerting feature of Grafana. An attacker can exploit this vulnerability to escalate privilege from editor     to admin by tricking an authenticated admin to click on a link. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10     contain a patch. As a workaround, it is possible to disable alerting or use legacy alerting.
    (CVE-2022-31097)

  - Grafana is an open-source platform for monitoring and observability. In versions 5.3 until 9.0.3, 8.5.9,     8.4.10, and 8.3.10, it is possible for a malicious user who has authorization to log into a Grafana     instance via a configured OAuth IdP which provides a login name to take over the account of another user     in that Grafana instance. This can occur when the malicious user is authorized to log in to Grafana via     OAuth, the malicious user's external user id is not already associated with an account in Grafana, the     malicious user's email address is not already associated with an account in Grafana, and the malicious     user knows the Grafana username of the target user. If these conditions are met, the malicious user can     set their username in the OAuth provider to that of the target user, then go through the OAuth flow to log     in to Grafana. Due to the way that external and internal user accounts are linked together during login,     if the conditions above are all met then the malicious user will be able to log in to the target user's     Grafana account. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch for this issue. As a     workaround, concerned users can disable OAuth login to their Grafana instance, or ensure that all users     authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.
    (CVE-2022-31107)

  - Grafana is an open-source platform for monitoring and observability. Versions prior to 9.1.6 and 8.5.13     are vulnerable to an escalation from admin to server admin when auth proxy is used, allowing an admin to     take over the server admin account and gain full control of the grafana instance. All installations should     be upgraded as soon as possible. As a workaround deactivate auth proxy following the instructions at:
    https://grafana.com/docs/grafana/latest/setup-grafana/configure-security/configure-authentication/auth-     proxy/ (CVE-2022-35957)

  - Grafana is an open-source platform for monitoring and observability. In versions prior to 8.5.13, 9.0.9,     and 9.1.6, Grafana is subject to Improper Preservation of Permissions resulting in privilege escalation on     some folders where Admin is the only used permission. The vulnerability impacts Grafana instances where     RBAC was disabled and enabled afterwards, as the migrations which are translating legacy folder     permissions to RBAC permissions do not account for the scenario where the only user permission in the     folder is Admin, as a result RBAC adds permissions for Editors and Viewers which allow them to edit and     view folders accordingly. This issue has been patched in versions 8.5.13, 9.0.9, and 9.1.6. A workaround     when the impacted folder/dashboard is known is to remove the additional permissions manually.
