CVE-2024-4151 in lunary
Summary
by MITRE • 05/20/2024
An Improper Access Control vulnerability exists in lunary-ai/lunary version 1.2.2, where users can view and update any prompts in any projects due to insufficient access control checks in the handling of PATCH and GET requests for template versions. This vulnerability allows unauthorized users to manipulate or access sensitive project data, potentially leading to data integrity and confidentiality issues.

The vulnerability identified as CVE-2024-4151 represents a critical improper access control flaw within the lunary-ai/lunary platform version 1.2.2. This security weakness stems from inadequate authorization mechanisms that fail to properly validate user permissions when processing template version requests. The affected system permits any authenticated user to access and modify prompts across all projects regardless of their actual role or assigned privileges, fundamentally undermining the application's security model. Such a flaw directly violates fundamental security principles and creates a pathway for unauthorized data manipulation that can compromise both data integrity and confidentiality.
The technical implementation of this vulnerability manifests through the lack of proper access control validation during PATCH and GET request processing for template versions. When users submit requests to modify or retrieve prompt templates, the system fails to verify whether the requesting user has appropriate authorization levels to perform these operations on the target project. This absence of access control checks creates a universal privilege escalation vector where any authenticated individual can traverse project boundaries and manipulate templates belonging to other users or teams. The flaw operates at the application logic level, specifically within the API endpoint handling mechanisms that should enforce project-level access controls.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass potential data integrity breaches and confidentiality compromises. An attacker with access to the system can not only read sensitive prompts and template configurations but also modify them to inject malicious content or alter project parameters. This capability enables sophisticated attacks including data exfiltration through prompt manipulation, injection of malicious code into templates, or the creation of backdoors within project configurations. The vulnerability affects the entire project ecosystem as it allows attackers to potentially gain access to all prompts across different projects, making it particularly dangerous for multi-tenant environments or organizations with multiple concurrent projects.
This vulnerability aligns with CWE-285, which specifically addresses improper access control issues in software systems, and maps to ATT&CK technique T1078.004 for valid accounts and T1566.001 for spearphishing via social media. The flaw represents a fundamental breakdown in the principle of least privilege, where users receive more access rights than necessary for their legitimate operations. Organizations utilizing this software may face significant compliance violations under data protection regulations such as gdpr, hipaa, and pci dss due to the unauthorized access capabilities this vulnerability enables. The impact is particularly severe in enterprise environments where prompt templates often contain proprietary information, customer data, or system configuration details that should remain restricted to authorized personnel only.
Mitigation strategies for CVE-2024-4151 require immediate implementation of proper access control validation mechanisms throughout the application's API endpoints. Organizations should deploy comprehensive authorization checks that verify user permissions against project ownership and role assignments before processing any template version requests. The fix must include mandatory authentication validation, role-based access controls, and proper session management to ensure that users can only access resources they are authorized to modify. Additionally, implementing audit logging for all template access and modification activities will help detect unauthorized access attempts and provide forensic evidence for security investigations. Organizations should also consider implementing rate limiting and monitoring mechanisms to detect potential abuse of the vulnerability and ensure proper access control enforcement across all API endpoints handling template data.
