Grafana is an open source observability and data visualization platform. Versions prior to 9.1.8 and 8.5.14 are vulnerable to a bypass in the plugin signature verification. An attacker can convince a server admin to download and successfully run a malicious plugin even though unsigned plugins are not allowed. Versions 9.1.8 and 8.5.14 contain a patch for this issue. As a workaround, do not install plugins downloaded from untrusted sources.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - grafana: session control failure may lead to information disclosure (CVE-2022-32275)

  - protobufjs: prototype pollution using user-controlled protobuf message (CVE-2023-36665)

  - The package protobufjs before 6.11.3 are vulnerable to Prototype Pollution which can allow an attacker to     add/modify properties of the Object.prototype. This vulnerability can occur in multiple ways: 1. by     providing untrusted user input to util.setProperty or to ReflectionObject.setParsedOption functions 2. by     parsing/loading .proto files (CVE-2022-25878)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Oracle Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2023-6420 advisory.

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0353-1 advisory.

  - Grafana is an open source observability and data visualization platform. Versions prior to 9.1.8 and     8.5.14 are vulnerable to a bypass in the plugin signature verification. An attacker can convince a server     admin to download and successfully run a malicious plugin even though unsigned plugins are not allowed.
    Versions 9.1.8 and 8.5.14 contain a patch for this issue. As a workaround, do not install plugins     downloaded from untrusted sources. (CVE-2022-31123)

  - Grafana is an open source observability and data visualization platform. Versions of Grafana for endpoints     prior to 9.1.8 and 8.5.14 could leak authentication tokens to some destination plugins under some     conditions. The vulnerability impacts data source and plugin proxy endpoints with authentication tokens.
    The destination plugin could receive a user's Grafana authentication token. Versions 9.1.8 and 8.5.14     contain a patch for this issue. As a workaround, do not use API keys, JWT authentication, or any HTTP     Header based authentication. (CVE-2022-31130)

  - Grafana is an open source observability and data visualization platform. Starting with version 5.0.0-beta1     and prior to versions 8.5.14 and 9.1.8, Grafana could leak the authentication cookie of users to plugins.
    The vulnerability impacts data source and plugin proxy endpoints under certain conditions. The destination     plugin could receive a user's Grafana authentication cookie. Versions 9.1.8 and 8.5.14 contain a patch for     this issue. There are no known workarounds. (CVE-2022-39201)

  - Grafana is an open source data visualization platform for metrics, logs, and traces. Versions prior to     9.1.8 and 8.5.14 allow one user to block another user's login attempt by registering someone else'e email     address as a username. A Grafana user's username and email address are unique fields, that means no other     user can have the same username or email address as another user. A user can have an email address as a     username. However, the login system allows users to log in with either username or email address. Since     Grafana allows a user to log in with either their username or email address, this creates an usual     behavior where `user_1` can register with one email address and `user_2` can register their username as     `user_1`'s email address. This prevents `user_1` logging into the application since `user_1`'s password     won't match with `user_2`'s email address. Versions 9.1.8 and 8.5.14 contain a patch. There are no     workarounds for this issue. (CVE-2022-39229)

  - Grafana is an open-source platform for monitoring and observability. Versions prior to 9.2.4, or 8.5.15 on     the 8.X branch, are subject to Improper Input Validation. Grafana admins can invite other members to the     organization they are an admin for. When admins add members to the organization, non existing users get an     email invite, existing members are added directly to the organization. When an invite link is sent, it     allows users to sign up with whatever username/email address the user chooses and become a member of the     organization. This introduces a vulnerability which can be used with malicious intent. This issue is     patched in version 9.2.4, and has been backported to 8.5.15. There are no known workarounds.
    (CVE-2022-39306)

  - Grafana is an open-source platform for monitoring and observability. When using the forget password on the     login page, a POST request is made to the `/api/user/password/sent-reset-email` URL. When the username or     email does not exist, a JSON response contains a user not found message. This leaks information to     unauthenticated users and introduces a security risk. This issue has been patched in 9.2.4 and backported     to 8.5.15. There are no known workarounds. (CVE-2022-39307)
