CVE-2024-1666 in lunary
Summary
by MITRE • 04/16/2024
In lunary-ai/lunary version 1.0.0, an authorization flaw exists that allows unauthorized radar creation. The vulnerability stems from the lack of server-side checks to verify if a user is on a free account during the radar creation process, which is only enforced in the web UI. As a result, attackers can bypass the intended account upgrade requirement by directly sending crafted requests to the server, enabling the creation of an unlimited number of radars without payment.

The vulnerability identified as CVE-2024-1666 resides within the lunary-ai/lunary application version 1.0.0 and represents a critical authorization flaw that undermines the platform's access control mechanisms. This security weakness specifically targets the radar creation functionality, where the application fails to enforce proper server-side validation of user account privileges. The flaw demonstrates a classic case of insufficient server-side checks that should have been implemented to prevent unauthorized access to premium features, creating a scenario where attackers can bypass intended business logic controls through direct API manipulation.
The technical implementation of this vulnerability stems from the application's reliance on client-side validation for account tier enforcement, particularly in the radar creation workflow. While the web user interface correctly enforces account limitations for free users, the underlying API endpoints lack the necessary server-side authorization checks to validate user permissions before processing radar creation requests. This architectural oversight creates a path for malicious actors to directly interact with the application's backend services through crafted HTTP requests, circumventing the intended user experience restrictions that should prevent free account holders from creating unlimited radars.
The operational impact of this vulnerability extends beyond simple unauthorized feature access, as it enables unlimited resource consumption and potential revenue loss for the service provider. Attackers can exploit this flaw to create an unlimited number of radars without any payment requirements, effectively bypassing the platform's monetization strategy. This unauthorized access could lead to system resource exhaustion, increased operational costs, and potential denial of service conditions for legitimate users. The vulnerability also represents a significant business risk as it allows unauthorized users to consume premium resources that should be restricted to paying customers, potentially causing substantial financial harm to the organization.
Security professionals should note that this vulnerability aligns with CWE-668, which describes "Exposure of Resource to Wrong Sphere," and demonstrates poor access control implementation. The flaw also maps to ATT&CK technique T1078.004, "Valid Accounts: Cloud Accounts," as it allows unauthorized access to premium features through legitimate account manipulation. Organizations should implement comprehensive server-side validation checks that verify user permissions and account status before processing any premium feature requests. The mitigation strategy should include enforcing proper authentication and authorization at the API level, implementing rate limiting for resource creation operations, and establishing robust session management controls to prevent unauthorized access to restricted functionality.
The remediation approach requires immediate implementation of server-side access control checks that validate user account tiers and permissions before allowing radar creation operations. This includes adding proper API endpoint validation that verifies account status, implementing comprehensive logging of all radar creation attempts, and establishing automated monitoring for unusual usage patterns that may indicate exploitation of this vulnerability. Additionally, organizations should conduct thorough security testing to identify similar authorization flaws in other application components and ensure that all business logic validation occurs server-side rather than relying on client-side enforcement mechanisms.
