CWE ID Description
CWE-863 The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
CWE-1220 The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.
CWE-639 The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

Executive Summary

This vulnerability allows a service account with user-management permissions in one organization to read, modify, disable, or delete users in other organizations on the same Grafana Enterprise instance. It occurs through the SCIM API due to an insecure direct object reference issue. Only instances with SCIM enabled are affected.

Detection Guidance

Check Grafana instance logs for unusual SCIM API activity, such as unauthorized user modifications across organizations. Verify if service accounts with user-management permissions exist outside their intended scope.

Impact Analysis

An attacker with access to a service account could manipulate user accounts across organizations, leading to unauthorized access, data breaches, or service disruption. This could compromise sensitive data and violate user privacy.

Compliance Impact

This vulnerability could lead to unauthorized access or modification of user data, violating GDPR's data protection principles or HIPAA's security requirements. Compliance may be compromised due to potential data breaches or lack of proper access controls.

Mitigation Strategies

Upgrade Grafana Enterprise to versions 11.6.0, 12.4.13, 13.0.11, 13.1.8, or 13.2.4. Disable SCIM if not required. Review and restrict service account permissions to prevent cross-organization access.
