CVE-2024-12778 is a vulnerability classified under CWE-770 (Allocation of Resources Without Limits or Throttling) found in aimhubio/aim version 3.25.0, a platform used for tracking machine learning experiments and metrics. The flaw arises because the Aim web API allows clients to request an unlimited number of tracked metrics in a single API call. The server is single-threaded, so when a large volume of metrics is requested simultaneously, it leads to excessive resource consumption, blocking the server's processing capability and causing it to become unresponsive. This results in a denial of service (DoS) condition, where legitimate users cannot access the service. The vulnerability does not require authentication or user interaction, making it remotely exploitable over the network. The CVSS v3.0 score of 7.5 reflects a high severity due to the network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact is limited to availability, with no direct confidentiality or integrity compromise. No patches or exploits are currently reported, but the lack of request throttling and single-threaded server design are key technical weaknesses that enable this attack.

For European organizations, especially those leveraging aimhubio/aim for machine learning experiment tracking and metrics aggregation, this vulnerability poses a significant availability risk. A successful exploitation can disrupt critical AI/ML workflows, delay model development cycles, and impact dependent business processes. Organizations in sectors such as finance, healthcare, and manufacturing that rely on AI-driven analytics could face operational downtime. The denial of service could also affect collaborative teams relying on Aim's web interface for real-time metric monitoring. Since the vulnerability is remotely exploitable without authentication, attackers can launch DoS attacks from outside the network, increasing the threat surface. The lack of confidentiality or integrity impact reduces the risk of data breaches but does not diminish the operational disruption potential. Given the increasing adoption of AI tools in Europe, the disruption caused by this vulnerability could have cascading effects on innovation and productivity.

To mitigate CVE-2024-12778, organizations should implement strict rate limiting and throttling on the number of metrics that can be requested per API call to prevent resource exhaustion. Introducing pagination or batching mechanisms for metric retrieval can reduce the load per request. Architectural improvements such as moving from a single-threaded to a multi-threaded or asynchronous server model will improve resilience against high request volumes. Monitoring API usage patterns and setting alert thresholds for abnormal request spikes can help detect exploitation attempts early. Network-level protections like Web Application Firewalls (WAFs) can be configured to block or throttle suspicious traffic targeting the metrics API endpoints. Until an official patch is released, organizations should consider restricting external access to the Aim web API or deploying it behind VPNs or zero-trust network architectures. Regularly updating to newer versions once patches are available is essential. Additionally, educating development and operations teams about safe API usage and resource management will help prevent similar issues.
