CVE-2024-24820 in icingaweb2-module-director
Summary
by MITRE • 02/09/2024
Icinga Director is a tool designed to make Icinga 2 configuration handling easy. Not any of Icinga Director's configuration forms used to manipulate the monitoring environment are protected against cross site request forgery (CSRF). It enables attackers to perform changes in the monitoring environment managed by Icinga Director without the awareness of the victim. Users of the map module in version 1.x, should immediately upgrade to v2.0. The mentioned XSS vulnerabilities in Icinga Web are already fixed as well and upgrades to the most recent release of the 2.9, 2.10 or 2.11 branch must be performed if not done yet. Any later major release is also suitable. Icinga Director will receive minor updates to the 1.8, 1.9, 1.10 and 1.11 branches to remedy this issue. Upgrade immediately to a patched release. If that is not feasible, disable the director module for the time being.

The vulnerability identified as CVE-2024-24820 affects Icinga Director, a critical configuration management tool for Icinga 2 monitoring systems that provides a web-based interface for managing complex monitoring environments. This tool serves as a bridge between administrators and the underlying Icinga 2 infrastructure, making it a prime target for attackers seeking to compromise monitoring operations. The vulnerability stems from the absence of cross site request forgery protection mechanisms within Icinga Director's configuration forms, which are used to manipulate the monitoring environment. This fundamental security flaw allows attackers to execute unauthorized modifications to the monitoring configuration without user consent or awareness, potentially leading to complete compromise of the monitoring infrastructure.
The technical implementation of this vulnerability resides in the lack of proper CSRF token validation within Icinga Director's web forms and API endpoints that handle configuration changes. According to CWE-352, this represents a classic cross site request forgery vulnerability where the application fails to verify that requests originate from legitimate users. The absence of anti-CSRF tokens means that authenticated users can be tricked into performing actions through malicious web pages or emails, making this a particularly dangerous vulnerability in monitoring environments where configuration changes can have severe operational consequences. Attackers could leverage this weakness to add or modify monitoring objects, disable alerts, or even redirect monitoring traffic to malicious endpoints.
The operational impact of this vulnerability extends beyond simple configuration modifications, as it can lead to complete disruption of monitoring services and potential security breaches within the infrastructure. When attackers exploit this vulnerability, they can manipulate critical monitoring parameters such as host checks, service checks, notification settings, and alert thresholds without the knowledge of legitimate administrators. This can result in missed security incidents, false positives, or complete monitoring outages that could go undetected for extended periods. The vulnerability affects the map module specifically in version 1.x, but the broader implications suggest that any configuration change made through the Director interface could be exploited, making this a systemic risk to the entire monitoring ecosystem.
The recommended mitigation strategies include immediate upgrades to patched versions of Icinga Director, specifically version 2.0 for the map module and the latest releases in the 1.8, 1.9, 1.10, and 1.11 branches. Organizations should also ensure they upgrade Icinga Web components to the most recent releases in the 2.9, 2.10, or 2.11 branches, as mentioned in the advisory. The ATT&CK framework categorizes this type of vulnerability under T1566 - Phishing, where attackers can leverage CSRF to trick users into performing malicious actions. When immediate upgrades are not feasible, administrators should consider disabling the director module temporarily, though this represents a more disruptive solution that would impact legitimate administrative operations. The vulnerability highlights the critical importance of implementing proper CSRF protection mechanisms in web applications that handle sensitive configuration data, particularly in security monitoring tools where unauthorized access can have cascading effects throughout the entire infrastructure.
