CVE-2025-2240 identifies a vulnerability in the smallrye-fault-tolerance component used within Red Hat Build of Apache Camel 4.8 for Quarkus 3.15, specifically affecting versions 6.3.0 and 6.5.0. The vulnerability arises from improperly controlled sequential memory allocation when the metrics URI is accessed. Each request to this URI causes the creation of a new object within the meterMap, which is not properly managed or released, leading to continuous growth in memory consumption. This uncontrolled allocation can exhaust system memory, resulting in an out-of-memory (OOM) condition that causes the application or service to crash or become unresponsive, effectively a denial of service (DoS). The vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, increasing its risk profile. The CVSS 3.1 score of 7.5 reflects a high severity due to the potential for complete service disruption. While no known exploits have been reported in the wild, the vulnerability's characteristics make it a viable target for attackers aiming to disrupt services. The affected product, Red Hat Build of Apache Camel for Quarkus, is widely used in enterprise integration and microservices architectures, making the impact potentially broad. The flaw does not impact confidentiality or integrity but severely affects availability. The lack of authentication requirements means any unauthenticated user with network access to the metrics endpoint can trigger the issue. The vulnerability was published on March 12, 2025, and is tracked under CVE-2025-2240.

For European organizations, the primary impact of CVE-2025-2240 is the risk of denial of service due to out-of-memory conditions triggered remotely. Enterprises relying on Red Hat Build of Apache Camel for Quarkus in critical business processes, including financial services, telecommunications, and public sector infrastructure, may experience service outages or degraded performance. This can disrupt business continuity, cause financial losses, and damage reputation. The vulnerability does not expose sensitive data but can indirectly impact availability of services relied upon by customers and partners. Organizations with exposed metrics endpoints or insufficient network segmentation are particularly vulnerable. The risk is heightened in environments where automated monitoring or alerting is not configured to detect abnormal memory usage. Given the widespread use of Red Hat and Apache Camel in Europe, especially in countries with strong enterprise IT sectors, the threat could affect a significant number of deployments. Additionally, the vulnerability could be leveraged as part of a multi-stage attack to distract or degrade defenses while other attacks are conducted.

To mitigate CVE-2025-2240, European organizations should first apply any available patches or updates from Red Hat as soon as they are released. In the absence of patches, organizations should restrict access to the metrics URI by implementing network-level controls such as firewall rules or VPN requirements to limit exposure to trusted users only. Rate limiting or throttling requests to the metrics endpoint can reduce the risk of memory exhaustion. Monitoring memory usage and application logs for unusual patterns can provide early warning signs of exploitation attempts. Additionally, consider disabling the metrics endpoint if it is not essential for operations. Employing application-layer gateways or API management solutions to enforce access policies and detect anomalous behavior can further reduce risk. Organizations should also review their incident response plans to include scenarios involving DoS attacks targeting application memory. Finally, educating developers and operations teams about secure coding and resource management best practices can help prevent similar issues in future releases.
