Summary
by MITRE • 10/29/2024
In version 1.3.2 of lunary-ai/lunary, an Insecure Direct Object Reference (IDOR) vulnerability exists. A user can view or delete external users by manipulating the 'id' parameter in the request URL. The application does not perform adequate checks on the 'id' parameter, allowing unauthorized access to external user data.

The vulnerability identified as CVE-2024-7474 represents a critical Insecure Direct Object Reference flaw within the lunary-ai/lunary application version 1.3.2. This security weakness stems from inadequate input validation and authorization checks when processing the 'id' parameter in API requests. The flaw allows malicious actors to manipulate URL parameters to access or manipulate data belonging to external users without proper authentication or authorization. Such vulnerabilities fall under CWE-284 which specifically addresses inadequate access control mechanisms and demonstrate how improper validation of user inputs can lead to unauthorized data exposure.
The technical implementation of this vulnerability occurs when the application processes user requests containing an 'id' parameter without verifying whether the requesting user has legitimate access rights to the target resource. This oversight creates a pathway where any authenticated user can potentially enumerate or manipulate user accounts belonging to other parties by simply altering the identifier value in the request URL. The vulnerability specifically affects the application's user management functionality where external user data is accessible through predictable API endpoints that lack proper access control enforcement. This type of flaw commonly occurs in applications that rely on direct object references rather than implementing proper access control checks before processing user requests.
The operational impact of this vulnerability extends beyond simple data exposure to include potential data manipulation and unauthorized actions against external user accounts. An attacker could not only view sensitive information belonging to other users but also delete user accounts or modify their data, leading to potential service disruption and data loss. The vulnerability affects the confidentiality, integrity, and availability of the application's user management system, potentially compromising user privacy and trust in the platform. This issue particularly impacts multi-tenant applications where user isolation is critical, as it allows privilege escalation through simple parameter manipulation.
Mitigation strategies for CVE-2024-7474 should focus on implementing proper access control mechanisms and input validation. The application must validate that users can only access resources they are authorized to view or modify by implementing proper authorization checks before processing any request containing an 'id' parameter. This includes implementing role-based access control or attribute-based access control mechanisms to ensure users cannot access external user data. The fix should involve replacing direct object references with indirect references that map to legitimate user resources, ensuring proper session management and authentication verification. Organizations should also implement proper logging and monitoring to detect unauthorized access attempts and ensure that all API endpoints perform adequate validation before executing any data manipulation operations. This vulnerability aligns with ATT&CK technique T1078 which covers valid accounts and privilege escalation, as it allows unauthorized access to user accounts through manipulation of application parameters.
