CVE-2014-2330 in Check_MK
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities in the Multisite GUI in Check_MK before 1.2.5i2 allow remote attackers to hijack the authentication of users for requests that (1) upload arbitrary snapshots, (2) delete arbitrary files, or possibly have other unspecified impact via unknown vectors.

The CVE-2014-2330 vulnerability represents a critical cross-site request forgery flaw within the Multisite GUI component of Check_MK monitoring software versions prior to 1.2.5i2. This vulnerability exists in the web-based administrative interface that allows system administrators to manage monitoring configurations and perform various operational tasks through a graphical user interface. The flaw specifically affects the way the application handles user authentication tokens and request validation within its multisite functionality, creating a pathway for malicious actors to exploit the trust relationship between authenticated users and the web application.
The technical implementation of this CSRF vulnerability stems from the absence of proper anti-CSRF token validation mechanisms within the affected GUI components. When authenticated users navigate to maliciously crafted web pages or click on compromised links, the attacker can leverage the user's existing session to execute unauthorized actions without requiring knowledge of the user's credentials. The vulnerability permits attackers to perform high-impact operations including uploading arbitrary snapshot files that could contain malicious code or scripts, as well as deleting arbitrary files from the system, potentially leading to complete system compromise or data destruction. The unspecified nature of additional attack vectors suggests that the vulnerability may enable further exploitation techniques beyond the documented capabilities.
From an operational impact perspective, this vulnerability poses severe risks to monitoring infrastructure security, as Check_MK systems are typically deployed in critical network monitoring environments where unauthorized access can lead to complete operational disruption. The ability to upload arbitrary snapshots could enable attackers to inject malicious monitoring configurations, while file deletion capabilities could destroy essential monitoring data or system components. Organizations relying on Check_MK for network monitoring and alerting would face significant operational challenges if this vulnerability were exploited, potentially leading to undetected network intrusions or complete service outages. The vulnerability affects the fundamental security model of the application by allowing attackers to leverage legitimate user sessions for unauthorized administrative actions.
Security practitioners should implement immediate mitigations including updating to Check_MK version 1.2.5i2 or later, which includes proper CSRF token validation mechanisms. Network segmentation and monitoring of administrative GUI access can help detect suspicious activities, while implementing web application firewalls with CSRF protection capabilities provides additional defense layers. The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications, and maps to ATT&CK technique T1566.001 for credential access through social engineering and T1078 for valid accounts usage. Organizations should also conduct comprehensive security assessments of their monitoring infrastructure to identify any other potential CSRF vulnerabilities in similar applications and ensure proper input validation and token management across all web-based administrative interfaces.
