Improper Authentication in Grafana - CVE-2023-3128

Vulnerability identifier: #VU77652

CSH Severity: High

CVSS v4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2023-3128

CWE-ID: CWE-287

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in Azure AD OAuth implementation. Grafana is validating Azure AD accounts based on the email claim. On Azure AD, the profile email field is not unique and can be easily modified. A remote attacker can modify their profile and provide the email address of  an existing Grafana user, bypass authentication process and gain unauthorized access to the application.

The vulnerability affects Grafana installations with Azure AD OAuth configured for a multi-tenant app.
