CVE-2024-11741 is a medium-severity vulnerability identified in the Grafana open-source monitoring and observability platform. The issue specifically affects the Grafana Alerting VictorOps integration component. This vulnerability arises because the integration was not properly protected, allowing users with Viewer-level permissions—who normally have read-only access—to potentially access sensitive information that should be restricted. The vulnerability is classified under CWE-200, which pertains to the exposure of sensitive information to unauthorized actors. The affected Grafana versions include 10.4.0, 11.1.0, 11.2.0, 11.3.0, and 11.4.0, with fixes released in subsequent patch versions (e.g., 11.5.0, 11.4.1, 11.3.3, 11.2.6, 11.1.11, 11.0.11, and 10.4.15). The CVSS v3.1 base score is 4.3, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) shows that the vulnerability can be exploited remotely over the network with low attack complexity, requires low privileges (Viewer role), no user interaction, and impacts confidentiality only, without affecting integrity or availability. There are no known exploits in the wild at the time of publication. This vulnerability could allow unauthorized users with limited access to view sensitive alerting configuration or data within the VictorOps integration, potentially leaking operational or security-related information that could be leveraged for further attacks or reconnaissance.

For European organizations, the exposure of sensitive information through Grafana's VictorOps integration can have several consequences. Grafana is widely used across industries for monitoring IT infrastructure, applications, and security telemetry. Unauthorized access to alerting configurations or sensitive monitoring data could reveal operational insights, incident response procedures, or security alerts. This information leakage may aid attackers in crafting targeted attacks or evading detection. Although the vulnerability does not allow modification or disruption of services, the confidentiality breach could undermine compliance with data protection regulations such as GDPR, especially if the exposed information includes personal or sensitive operational data. Organizations relying on Grafana for critical infrastructure monitoring could face increased risk of reconnaissance by malicious actors. The medium severity suggests a moderate risk, but the ease of exploitation by users with Viewer permissions—who are commonly granted in many organizations—raises concerns about insider threats or compromised low-privilege accounts.

European organizations should promptly upgrade affected Grafana instances to the fixed versions listed (e.g., 11.5.0 or later). If immediate upgrading is not feasible, organizations should review and restrict Viewer role assignments to only trusted users, minimizing exposure. Additionally, audit and monitor access logs for unusual Viewer activity related to the VictorOps integration. Implement network segmentation and access controls to limit exposure of Grafana instances to trusted networks and users. Organizations should also review the configuration of the VictorOps integration to ensure it does not expose unnecessary sensitive data. Employing multi-factor authentication (MFA) for all Grafana users, including Viewers, can reduce the risk of account compromise. Finally, integrate Grafana monitoring with security information and event management (SIEM) systems to detect anomalous access patterns promptly.
