CVE-2024-7475 is an improper access control vulnerability categorized under CWE-862 affecting lunary-ai/lunary, specifically version 1.3.2. The vulnerability allows an attacker with no privileges and no user interaction to remotely update the Security Assertion Markup Language (SAML) configuration without authorization. SAML is a widely used protocol for single sign-on (SSO) and federated identity management, and its configuration controls how authentication assertions are handled between identity providers and service providers. By manipulating the SAML configuration, an attacker can alter authentication flows, potentially injecting fraudulent login requests or bypassing authentication mechanisms. This can lead to unauthorized access to user accounts and theft of sensitive user information. The vulnerability has a CVSS v3.0 score of 9.1, indicating critical severity due to its network attack vector, lack of required privileges, and high impact on confidentiality and integrity. Although no public exploits are currently known, the nature of the vulnerability makes it a high-value target for attackers aiming to compromise authentication systems. The root cause is missing authorization checks on the API or interface that manages SAML configuration updates, allowing any remote actor to make unauthorized changes. This flaw highlights the importance of enforcing strict access control policies on sensitive configuration endpoints in identity management software.

For European organizations, the impact of CVE-2024-7475 is significant due to the critical role of SAML in enterprise authentication and access control. Exploitation can lead to unauthorized access to corporate resources, data breaches involving personal and sensitive information, and potential lateral movement within networks. This can undermine trust in identity providers and disrupt business operations reliant on federated authentication. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitivity of their data and regulatory requirements like GDPR. The breach of user confidentiality and integrity can result in severe legal and financial consequences. Additionally, the lack of authentication requirement for exploitation increases the attack surface, making it easier for threat actors to target vulnerable systems remotely. The absence of known patches or mitigations at the time of disclosure further elevates the risk for affected entities.

To mitigate CVE-2024-7475, organizations should immediately audit and restrict access to the SAML configuration management interfaces within lunary-ai/lunary deployments. Implement role-based access control (RBAC) or attribute-based access control (ABAC) to ensure only authorized administrators can modify SAML settings. Network-level protections such as firewall rules or VPN requirements should be applied to limit access to configuration endpoints. Monitor logs for unauthorized or suspicious changes to authentication configurations. If possible, apply vendor patches or updates as soon as they become available. In the interim, consider disabling remote configuration capabilities or isolating the affected service from untrusted networks. Conduct thorough penetration testing and code review to identify and remediate similar access control weaknesses. Educate administrators on secure configuration management practices and enforce multi-factor authentication for administrative access. Finally, maintain an incident response plan to quickly address any exploitation attempts.
