Description

Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Installations of Icinga 2 with the IDO writer enabled are affected. If you use service custom variables in role restrictions, and you regularly decommission service objects, users with said roles may still have access to a collection of content. Note that this only applies if a role has implicitly permitted access to hosts, due to permitted access to at least one of their services. If access to a host is permitted by other means, no sensible information has been disclosed to unauthorized users. This issue has been resolved in versions 2.8.6, 2.9.6 and 2.10 of Icinga Web 2.

Technical Analysis

CVE-2022-24714 is an authorization vulnerability classified under CWE-863, affecting Icinga Web 2, an open-source monitoring web interface and framework widely used for IT infrastructure and service monitoring. The vulnerability specifically impacts installations of Icinga 2 that have the IDO (Icinga Data Output) writer enabled, which is a common configuration for persisting monitoring data. The issue arises when service custom variables are used in role-based access restrictions and service objects are regularly decommissioned. In such scenarios, users assigned roles with permissions implicitly granted through access to at least one service may retain unauthorized access to collections of content related to decommissioned services. This occurs because the authorization logic does not properly revoke access when service objects are removed, leading to potential exposure of monitoring data that should no longer be accessible. Importantly, this vulnerability only affects access control when host access is implicitly granted via service permissions; if host access is granted through other means, no sensitive information is disclosed. The flaw was addressed in Icinga Web 2 versions 2.8.6, 2.9.6, and 2.10, indicating that users running earlier versions remain vulnerable. There are no known exploits in the wild, and the vulnerability requires authenticated users with specific role permissions to exploit, limiting its attack surface but still posing a risk within organizations that rely on Icinga Web 2 for monitoring critical infrastructure.

Potential Impact

For European organizations, the impact of this vulnerability can be significant, especially for those in sectors with stringent monitoring and compliance requirements such as finance, telecommunications, energy, and government. Unauthorized access to monitoring data could lead to exposure of sensitive operational details, including service statuses, custom variables, and potentially configuration information. This could facilitate further reconnaissance by malicious insiders or external attackers who have compromised user credentials. While the vulnerability does not directly allow remote code execution or system takeover, the leakage of monitoring data can undermine operational security, enable targeted attacks, and violate data protection regulations such as GDPR if sensitive information is exposed. Organizations relying heavily on Icinga Web 2 for real-time monitoring and incident response may experience degraded trust in their monitoring systems, potentially delaying detection and remediation of actual incidents. The medium severity rating reflects the limited scope of exploitation (authenticated users with specific roles) but acknowledges the potential for meaningful information disclosure and operational impact.

Mitigation Recommendations

To mitigate this vulnerability, European organizations should prioritize upgrading Icinga Web 2 installations to versions 2.8.6, 2.9.6, 2.10, or later, where the authorization flaw has been fixed. In addition, organizations should audit role-based access controls, especially roles that use service custom variables for permissions, to ensure that decommissioned service objects do not inadvertently grant access. Implementing strict lifecycle management for service objects and regularly reviewing and cleaning up obsolete roles and permissions can reduce residual access risks. Monitoring and logging user access to sensitive monitoring data can help detect anomalous access patterns indicative of exploitation attempts. Organizations should also consider restricting the number of users with roles that implicitly grant access to hosts via services, applying the principle of least privilege. Where feasible, segregate monitoring environments and restrict access to critical monitoring interfaces through network segmentation and multi-factor authentication to further reduce risk. Finally, maintaining an up-to-date inventory of affected systems and integrating vulnerability management processes to track and remediate such issues promptly is essential.
