CVE-2022-45399 is a security vulnerability identified in the Jenkins Cluster Statistics Plugin, specifically versions 0.4.6 and earlier. The vulnerability arises due to a missing permission check, which allows an attacker with limited privileges (requiring some level of authentication but no user interaction) to delete recorded Jenkins Cluster Statistics data. This plugin is used within Jenkins environments to collect and display cluster-wide statistics, which can be critical for monitoring and managing Jenkins instances in large-scale CI/CD pipelines. The vulnerability is classified under CWE-862 (Missing Authorization), indicating that the plugin fails to properly enforce authorization controls before allowing deletion operations. The CVSS v3.1 base score is 4.3 (medium severity), with the vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, meaning the attack can be performed remotely over the network with low attack complexity, requires low privileges, no user interaction, and impacts only the integrity of the statistics data without affecting confidentiality or availability. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability could be exploited by authenticated users who have limited permissions but are not authorized to delete cluster statistics, potentially leading to loss of important monitoring data and impacting operational visibility of Jenkins clusters.

For European organizations relying on Jenkins for continuous integration and deployment, especially those using the Cluster Statistics Plugin, this vulnerability could undermine the integrity of their monitoring data. Loss or deletion of cluster statistics can impair the ability of DevOps teams to track performance, detect anomalies, or audit usage patterns, potentially delaying incident response or masking other malicious activities. While the vulnerability does not directly impact confidentiality or availability, the integrity loss could indirectly affect operational decision-making and compliance reporting. Organizations with large Jenkins deployments or those in regulated industries where audit trails are critical (e.g., finance, healthcare, manufacturing) may face increased risk. Additionally, attackers with low-level access could exploit this vulnerability to cover tracks or disrupt monitoring without needing elevated privileges or user interaction, increasing the threat surface.

1. Implement strict access controls and role-based permissions within Jenkins to ensure that only fully trusted users have any level of write or delete permissions on the Cluster Statistics Plugin data. 2. Monitor Jenkins user activity logs for unusual deletion events or access patterns related to the Cluster Statistics Plugin. 3. If possible, temporarily disable or remove the Cluster Statistics Plugin until an official patch or update is released by the Jenkins project. 4. Regularly back up Jenkins configuration and plugin data, including cluster statistics, to enable recovery in case of unauthorized deletions. 5. Apply the principle of least privilege rigorously across Jenkins users, ensuring that users with only limited privileges cannot perform deletion operations. 6. Stay updated with Jenkins security advisories and apply patches promptly once available. 7. Consider implementing additional monitoring or alerting on Jenkins API calls related to cluster statistics deletion to detect exploitation attempts early.
