CVE-2024-1626 in lunary
Summary
by MITRE • 04/16/2024
An Insecure Direct Object Reference (IDOR) vulnerability exists in the lunary-ai/lunary repository, version 0.3.0, within the project update endpoint. The vulnerability allows authenticated users to modify the name of any project within the system without proper authorization checks, by directly referencing the project's ID in the PATCH request to the '/v1/projects/:projectId' endpoint. This issue arises because the endpoint does not verify if the provided project ID belongs to the currently authenticated user, enabling unauthorized modifications across different organizational projects.

The vulnerability described in CVE-2024-1626 represents a critical Insecure Direct Object Reference flaw that undermines the authorization mechanisms of the lunary-ai/lunary application. This weakness manifests within the project update endpoint of version 0.3.0, where authenticated users can manipulate project data without proper access controls. The vulnerability specifically targets the '/v1/projects/:projectId' endpoint, which fails to validate whether the requesting user has legitimate authorization to modify the targeted project resource. This design flaw allows attackers to construct malicious PATCH requests with arbitrary project IDs, effectively bypassing the intended access controls that should restrict modifications to only those projects owned by the authenticated user.
The technical implementation of this vulnerability stems from a fundamental lack of proper input validation and authorization checks within the backend service. When a user submits a PATCH request to update a project, the system should verify that the project ID corresponds to a resource that belongs to the authenticated user's organizational context. However, the current implementation directly accepts the project ID parameter without performing ownership verification, creating a direct reference to objects that should be protected by access control mechanisms. This pattern aligns with CWE-639, which specifically addresses Insecure Direct Object Reference vulnerabilities where applications fail to verify that the user has proper authorization to access the requested resource. The flaw essentially allows any authenticated user to traverse the application's object reference system and modify resources they should not have access to, creating a significant privilege escalation risk.
The operational impact of this vulnerability extends beyond simple data modification, potentially enabling more severe security consequences within the application's ecosystem. An attacker with valid authentication credentials could exploit this weakness to modify project configurations, potentially disrupting service operations or gaining unauthorized access to sensitive project data. The vulnerability particularly affects multi-tenant environments where multiple organizations share the same application instance, as it allows cross-organizational project manipulation. This capability could enable data leakage between organizations, project hijacking, or service disruption attacks. From an attacker's perspective, the vulnerability requires minimal skill to exploit since it only requires knowledge of the target project ID and the ability to make authenticated requests, making it highly attractive for exploitation in real-world scenarios.
From a cybersecurity framework perspective, this vulnerability directly maps to several ATT&CK techniques including T1078 for valid accounts and T1566 for credential harvesting, as unauthorized modifications can occur through legitimate authenticated sessions. The issue also relates to privilege escalation and lateral movement within the application's access control model. Organizations should implement robust input validation and access control mechanisms to prevent such vulnerabilities, including proper object ownership verification, role-based access controls, and comprehensive authorization checks. The recommended mitigations include implementing strict project ownership verification before allowing any modifications, adding audit logging for project changes, and ensuring that all resource access requests are validated against the authenticated user's permissions. Additionally, organizations should consider implementing automated security scanning tools to detect similar patterns in their codebase, as this type of vulnerability often occurs in applications where authorization logic is not properly enforced during resource manipulation operations.
