CVE-2025-67013 identifies a security vulnerability in the ETL Systems Ltd DEXTRA Series Digital L-Band Distribution System version 1.8. The core issue is the lack of Cross-Site Request Forgery (CSRF) protections on the web management interface, specifically on critical configuration endpoints. CSRF is an attack technique that forces an authenticated user’s browser to submit unwanted requests to a web application, potentially causing unauthorized actions. In this case, the absence of CSRF tokens or validation of Origin/Referer headers means that an attacker can craft malicious web pages or links that, when visited by an authenticated administrator, execute unauthorized configuration changes on the device. These configuration changes could alter system behavior, degrade service quality, or open further attack vectors. The vulnerability does not require user interaction beyond visiting a malicious page while authenticated, and no authentication bypass is needed since the victim must be logged in. No CVSS score has been assigned yet, and there are no known exploits in the wild as of the publication date. The DEXTRA Series is used in satellite and broadcast communication environments to distribute L-Band signals, making the integrity and availability of these systems critical. The lack of CSRF protection is a significant security oversight that could be exploited to disrupt operations or compromise system integrity.

For European organizations, particularly those in satellite communications, broadcasting, and related infrastructure sectors, this vulnerability poses a significant risk. Unauthorized configuration changes could lead to service outages, signal disruption, or interception of broadcast content, impacting business continuity and regulatory compliance. Confidentiality could be compromised if attackers alter settings to redirect or capture data streams. Integrity is at risk due to potential unauthorized modifications of system parameters. Availability may be affected if malicious configurations cause system failures or degraded performance. Given the critical role of L-Band distribution in satellite communications, disruptions could have cascading effects on media distribution, emergency communications, and defense-related operations. Organizations relying on ETL Systems’ DEXTRA Series must consider this vulnerability seriously, especially as no patches or mitigations are currently published. The absence of known exploits does not diminish the risk, as the vulnerability is straightforward to exploit with minimal prerequisites.

Organizations should immediately restrict access to the web management interface of the DEXTRA Series devices to trusted networks and personnel only, ideally via VPN or isolated management VLANs. Implement network-level controls such as firewall rules to limit access to the management interface. Monitor administrative access logs for unusual activity. Until ETL Systems releases a patch or firmware update, consider deploying web application firewalls (WAFs) that can detect and block CSRF attack patterns. Educate administrators to avoid visiting untrusted websites while logged into management consoles. If possible, disable web management interfaces when not in use or replace them with more secure management methods such as SSH with strong authentication. Engage with ETL Systems support to obtain timelines for security updates and request guidance on interim mitigations. Conduct regular security assessments and penetration tests focusing on management interfaces to detect similar vulnerabilities.
