CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2022-31123 – Grafana plugin signature bypass vulnerability
https://notcve.org/view.php?id=CVE-2022-31123
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. • https://github.com/grafana/grafana/releases/tag/v9.1.8 https://github.com/grafana/grafana/security/advisories/GHSA-rhxj-gh46-jvw8 https://security.netapp.com/advisory/ntap-20221124-0002 https://access.redhat.com/security/cve/CVE-2022-31123 https://bugzilla.redhat.com/show_bug.cgi?id=2131147 • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 7.6EPSS: 0%CPEs: 3EXPL: 0CVE-2022-36062 – Grafana folders admin only permission privilege escalation
https://notcve.org/view.php?id=CVE-2022-36062
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. • https://github.com/grafana/grafana/security/advisories/GHSA-p978-56hq-r492 https://security.netapp.com/advisory/ntap-20221215-0001 • CWE-281: Improper Preservation of Permissions •
CVSS: 6.6EPSS: 0%CPEs: 4EXPL: 0CVE-2022-35957 – Authentication Bypass in Grafana via auth proxy allowing escalation from admin to server admin
https://notcve.org/view.php?id=CVE-2022-35957
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/ Grafana es una plataforma de código abierto para la monitorización y la observabilidad. Las versiones anteriores a 9.1.6 y 8.5.13, son vulnerables a una escalada de admin a server admin cuando es usado auth proxy, lo que permite a un admin tomar la cuenta de server admin y obtener el control total de la instancia de grafana. • https://github.com/grafana/grafana/security/advisories/GHSA-ff5c-938w-8c9q https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WYU5C2RITLHVZSTCWNGQWA6KSPYNXM2H https://security.netapp.com/advisory/ntap-20221215-0001 https://access.redhat.com/security/cve/CVE-2022-35957 https://bugzilla.redhat.com/show_bug.cgi?id=2125514 • CWE-288: Authentication Bypass Using an Alternate Path or Channel CWE-290: Authentication Bypass by Spoofing •
CVSS: 8.3EPSS: 0%CPEs: 1EXPL: 0CVE-2022-31176 – Grafana Image Renderer leaking files
https://notcve.org/view.php?id=CVE-2022-31176
Grafana Image Renderer is a Grafana backend plugin that handles rendering of panels & dashboards to PNGs using a headless browser (Chromium/Chrome). An internal security review identified an unauthorized file disclosure vulnerability. It is possible for a malicious user to retrieve unauthorized files under some network conditions or via a fake datasource (if user has admin permissions in Grafana). All Grafana installations should be upgraded to version 3.6.1 as soon as possible. As a workaround it is possible to [disable HTTP remote rendering](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/#plugingrafana-image-renderer). • https://github.com/grafana/grafana-image-renderer/pull/364 https://github.com/grafana/grafana-image-renderer/security/advisories/GHSA-2cfh-233g-m4c5 https://security.netapp.com/advisory/ntap-20221209-0004 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-306: Missing Authentication for Critical Function •
CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2022-31107 – Grafana account takeover via OAuth vulnerability
https://notcve.org/view.php?id=CVE-2022-31107
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. • https://github.com/grafana/grafana/security/advisories/GHSA-mx47-6497-3fv2 https://grafana.com/docs/grafana/next/release-notes/release-notes-8-4-10 https://grafana.com/docs/grafana/next/release-notes/release-notes-8-5-9 https://grafana.com/docs/grafana/next/release-notes/release-notes-9-0-3 https://security.netapp.com/advisory/ntap-20220901-0010 https://access.redhat.com/security/cve/CVE-2022-31107 https://bugzilla.redhat.com/show_bug.cgi?id=2104367 • CWE-287: Improper Authentication CWE-863: Incorrect Authorization •
