CVE-2024-5710 is a vulnerability classified under CWE-862 (Missing Authorization) affecting berriai/litellm version 1.34.34. The issue lies in the team management functionality where access control checks are insufficient or missing on various endpoints. This flaw allows an attacker with low privileges to bypass authorization and perform unauthorized operations such as creating, updating, viewing, deleting, blocking, and unblocking any teams, as well as adding or removing any members from any teams. The vulnerability is network exploitable (AV:N) but requires low privileges (PR:L) and no user interaction (UI:N). The impact is primarily on integrity (I:H), as unauthorized modifications to team structures and memberships can disrupt organizational workflows and potentially lead to further privilege escalation or insider threats. Availability and confidentiality are not directly impacted. The CVSS score of 5.3 reflects a medium severity due to the requirement for some privileges and the complexity of exploitation. No patches are currently linked, and no known exploits have been reported in the wild, indicating the vulnerability is newly disclosed. Organizations using berriai/litellm should assess their exposure and implement compensating controls until patches are available.

For European organizations, this vulnerability poses a significant risk to the integrity of team management within berriai/litellm deployments. Unauthorized manipulation of teams and memberships can lead to disruption of collaboration, unauthorized access to sensitive projects, and potential insider threats if attackers add malicious actors to critical teams. This could affect sectors relying heavily on team-based workflows such as technology, finance, government, and research institutions. The lack of confidentiality and availability impact reduces the risk of data leakage or denial of service, but the integrity compromise could facilitate further attacks or data manipulation. Organizations with regulatory compliance requirements around access control and data integrity (e.g., GDPR, NIS2 Directive) may face compliance risks if this vulnerability is exploited. The medium severity rating suggests prioritization but not emergency response unless combined with other vulnerabilities or active exploitation.

1. Monitor berriai/litellm vendor communications closely for official patches or updates addressing CVE-2024-5710 and apply them promptly. 2. Until patches are available, restrict access to team management endpoints to trusted administrators only, using network segmentation, firewall rules, or API gateways. 3. Implement strict role-based access controls (RBAC) within the application to limit team management capabilities to authorized personnel. 4. Conduct regular audits of team membership and management logs to detect unauthorized changes or suspicious activities. 5. Employ anomaly detection tools to flag unusual team creation, deletion, or membership modifications. 6. Educate administrators and users about the risks of privilege escalation and enforce the principle of least privilege. 7. If possible, disable or limit team management features temporarily in high-risk environments. 8. Integrate multi-factor authentication (MFA) for accounts with team management privileges to reduce risk of credential compromise. 9. Prepare incident response plans specific to unauthorized access or manipulation of team structures.
