CVE-2026-38057 in Evolution iQ-Series terminals
Summary
by MITRE • 07/10/2026
The iDirect iQ200 does not validate CSRF tokens on state-changing API endpoints after authentication. The /api/reboot endpoint accepts POST requests authenticated solely by a session cookie that lacks the SameSite attribute. A remote attacker can host a malicious web page that, when visited by an authenticated administrator, automatically submits a cross-site POST request causing an immediate device reboot and satellite link loss. Repeated attacks can sustain a denial-of-service condition.

The iDirect iQ200 network device presents a critical cross-site request forgery vulnerability that compromises the integrity of its authentication mechanisms and exposes operational infrastructure to unauthorized control. This flaw exists within the device's API endpoint handling where the /api/reboot endpoint fails to implement proper CSRF token validation despite requiring authentication through session cookies. The vulnerability represents a fundamental breakdown in the security model that allows attackers to execute arbitrary administrative commands without proper authorization, effectively undermining the device's access controls and operational stability.
The technical implementation of this vulnerability stems from the absence of CSRF protection mechanisms on state-changing API endpoints within the iQ200 device. When an administrator authenticates to the system, they receive a session cookie that lacks the SameSite attribute, which is a critical security feature designed to prevent cross-site request forgery attacks by ensuring that cookies are only sent with requests originating from the same site. Without this protection, the session cookie becomes vulnerable to exploitation through malicious web pages that can trigger automatic form submissions when visited by authenticated users. This particular implementation flaw allows for immediate execution of administrative functions without requiring additional authentication factors or validation steps that should normally accompany such critical operations.
The operational impact of this vulnerability extends beyond simple device rebooting to encompass significant business continuity and security implications. When exploited, the vulnerability enables remote attackers to cause immediate device reboots through carefully crafted malicious web pages that automatically submit POST requests to the vulnerable endpoint. The consequences include instantaneous satellite link loss, which can disrupt critical communications infrastructure, particularly in mission-critical applications such as telecommunications, maritime communications, or emergency services where continuous connectivity is essential. The ability to repeatedly trigger these reboots creates a sustained denial-of-service condition that can effectively disable the device and compromise network operations for extended periods.
This vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery (CSRF) weaknesses in web applications, and demonstrates a clear violation of secure coding practices that should be implemented to protect state-changing operations. The attack vector follows patterns consistent with ATT&CK technique T1190, which describes exploiting vulnerabilities in remote services to gain unauthorized access to systems. Additionally, the lack of proper SameSite attribute implementation on session cookies represents a failure to adhere to security best practices outlined in various industry standards including NIST SP 800-53 and ISO/IEC 27001 controls related to secure authentication and session management.
Organizations should immediately implement mitigations including deploying CSRF tokens on all state-changing API endpoints, implementing proper SameSite attributes on session cookies, and restricting API access through network segmentation. The device firmware should be updated to enforce token validation mechanisms before executing administrative functions, while network administrators should consider implementing additional monitoring controls to detect unauthorized reboot activities. The vulnerability also highlights the need for comprehensive security testing of network infrastructure devices, particularly those handling critical communications systems, to identify similar implementation flaws that could lead to operational disruptions and security breaches.
