Analysis
Critical improper access control vulnerability in Mist Community Edition's API Token Handler (create_token function) that allows unauthenticated remote attackers to manipulate token generation. Affected versions up to 4.7.1 are vulnerable; the vulnerability has been publicly disclosed with exploitation techniques available, and upgrading to version 4.7.2 provides the necessary fix. The CVSS 7.3 score reflects medium-to-high severity with potential for confidentiality, integrity, and availability impact.
Technical Context
The vulnerability exists in src/mist/api/auth/views.py within the create_token function of Mist Community Edition's REST API authentication layer. The root cause is classified as CWE-266 (Improper Privilege Management), indicating that the token creation endpoint fails to properly enforce access controls or privilege boundaries before issuing API tokens. This suggests attackers can bypass authentication or authorization checks during token generation, potentially allowing them to obtain tokens with elevated privileges or create tokens on behalf of other users. The affected component is part of the API authentication framework, making this a critical control point in the application's security posture. CPE context: cpe:2.3:a:mist:mist_community_edition:*:*:*:*:*:*:*:* (versions <= 4.7.1).
Affected Products
- product: Mist Community Edition; vendor: Mist; affected_versions: up to and including 4.7.1; vulnerable_component: src/mist/api/auth/views.py - create_token function; patched_version: 4.7.2; patch_identifier: db10ecb62ac832c1ed4924556d167efb9bc07fad
Remediation
- action: Immediate Upgrade; details: Upgrade Mist Community Edition to version 4.7.2 or later. Patch commit db10ecb62ac832c1ed4924556d167efb9bc07fad addresses the improper access control in the create_token function. - action: Interim Mitigation (if upgrade delayed); details: Implement network-level access controls restricting access to the API token endpoint (typically /api/auth/token or similar) to trusted networks. Consider implementing rate limiting and monitoring for abnormal token creation patterns. Review audit logs for unauthorized token creation attempts. - action: Post-Patch Verification; details: After upgrading to 4.7.2, audit all API tokens for unauthorized or suspicious creation timestamps. Revoke any tokens created during the vulnerability window. Rotate credentials for service accounts that may have been compromised. - action: Monitoring; details: Implement logging and alerting on the /api/auth/token endpoint for: (1) Failed authentication attempts, (2) Token creation without proper authorization context, (3) Unusual token creation rates, (4) Tokens created for unexpected user accounts or service principals.
