CVE-2025-4009 in SVDN 3080ipx-10G
Summary
by MITRE • 05/28/2025
The Evertz SVDN 3080ipx-10G is a High Bandwidth Ethernet Switching Fabric for Video Application. This device exposes a web management interface on port 80. This web management interface can be used by administrators to control product features, setup network switching, and register license among other features. The application has been developed in PHP with the webEASY SDK, also named ‘ewb’ by Evertz.
This web interface has two endpoints that are vulnerable to arbitrary command injection and the authentication mechanism has a flaw leading to authentication bypass.
Remote unauthenticated attackers can gain arbitrary command execution with elevated privileges ( root ) on affected devices.
This level of access could lead to serious business impact such as the interruption of media streaming, modification of media being streamed, alteration of closed captions being generated, among others.

The Evertz SVDN 3080ipx-10G represents a critical network infrastructure component designed for high-bandwidth video switching applications in professional media environments. This device operates as a sophisticated switching fabric that handles video streams with high reliability and performance standards. The system exposes a web management interface on port 80, providing administrators with comprehensive control over device features including network switching configurations and license registration processes. The web interface is built using PHP technology with the webEASY SDK framework, commonly referred to as 'ewb' by Evertz, which creates a complex attack surface due to the combination of web application vulnerabilities and network infrastructure exposure.
The vulnerability landscape for this device presents two distinct but interconnected attack vectors that together create a severe security risk. The first vector involves two specific endpoints within the web management interface that are susceptible to arbitrary command injection attacks, allowing attackers to execute malicious commands on the underlying system. The second vector stems from a fundamental flaw in the authentication mechanism that enables unauthenticated attackers to bypass the system's access controls entirely. This dual vulnerability creates a pathway where remote attackers can achieve complete system compromise without requiring valid credentials, effectively eliminating the traditional perimeter security controls that would normally protect such critical infrastructure.
The operational impact of this vulnerability extends far beyond simple system compromise, creating substantial business disruption risks for organizations relying on this equipment. The root-level access granted to attackers enables them to manipulate video streams in real-time, potentially causing service interruptions that could affect broadcast schedules and live event coverage. The ability to modify media content during transmission creates serious risks for content integrity, while the capacity to alter closed captioning data could result in compliance violations and accessibility issues. These capabilities directly violate industry standards for media infrastructure security and could result in significant financial and reputational damage to organizations depending on this equipment for their core operations.
Organizations must implement immediate mitigations to protect against this vulnerability, including network segmentation to isolate the affected device from untrusted networks and implementing strict firewall rules to restrict access to port 80. The most effective long-term solution involves applying vendor-provided patches once available, though organizations should consider network monitoring and intrusion detection systems to identify potential exploitation attempts. This vulnerability aligns with CWE-77 and CWE-287 categories, representing command injection and authentication bypass flaws respectively, which together create a dangerous combination that violates fundamental security principles. The attack pattern follows ATT&CK techniques related to privilege escalation and command execution, making this vulnerability particularly concerning for security teams responsible for protecting media and broadcast infrastructure environments.
