CVE-2025-28131 in Network Analyzer
Summary
by MITRE • 04/01/2025
A Broken Access Control vulnerability in Nagios Network Analyzer 2024R1.0.3 allows low-privilege users with "Read-Only" access to perform administrative actions, including stopping system services and deleting critical resources. This flaw arises due to improper authorization enforcement, enabling unauthorized modifications that compromise system integrity and availability.

The vulnerability identified as CVE-2025-28131 represents a critical Broken Access Control flaw in Nagios Network Analyzer version 2024R1.0.3 which fundamentally undermines the application's security model. This issue allows users with minimal privileges to escalate their capabilities and execute administrative functions that should be restricted to authorized personnel only. The vulnerability manifests through improper authorization enforcement mechanisms that fail to properly validate user permissions before executing sensitive operations. Security researchers have identified that the system does not adequately verify access rights when processing requests for system service management or resource deletion operations, creating a pathway for privilege escalation attacks.
The technical implementation of this vulnerability stems from inadequate input validation and authorization checks within the application's access control framework. When low-privilege users attempt to perform administrative actions, the system fails to properly authenticate their elevated permissions, allowing them to bypass security controls that should prevent such operations. This flaw operates at the core of the application's authorization model, where the distinction between read-only and administrative privileges becomes meaningless due to insufficient validation logic. The vulnerability specifically affects the service management and resource deletion functions, which are typically restricted to users with administrative or root-level privileges. This misconfiguration creates a dangerous situation where unauthorized individuals can disrupt system operations by stopping critical services or removing essential resources.
From an operational perspective, this vulnerability poses significant risks to system integrity and availability within network monitoring environments. The ability of read-only users to stop system services can lead to complete service disruption and loss of network visibility, which is particularly concerning for organizations relying on continuous monitoring capabilities. When critical resources are deleted by unauthorized users, it can result in data loss, configuration corruption, and extended recovery periods that impact business continuity. The impact extends beyond immediate service disruption to include potential data integrity compromises, as the deletion of critical monitoring components can lead to gaps in network surveillance. Organizations may experience increased incident response times due to the loss of monitoring capabilities, while also facing potential compliance violations if monitoring systems are compromised.
The vulnerability aligns with CWE-285, which addresses improper authorization issues in software systems, and demonstrates characteristics consistent with ATT&CK technique T1078.004 for valid accounts and T1485 for data destruction. Organizations should implement immediate mitigations including thorough access control reviews, implementation of role-based access controls with least privilege principles, and regular security assessments of authorization mechanisms. System administrators should consider implementing additional monitoring for unusual administrative activity patterns and establish strict audit trails for all service management and resource deletion operations. The recommended remediation approach includes patching the application to enforce proper authorization checks, implementing multi-factor authentication for administrative functions, and conducting comprehensive security training for all users to understand the importance of access control mechanisms. Organizations should also consider network segmentation and additional defensive measures to limit the potential impact of such vulnerabilities in their operational environments.
