The Evertz SDVN 3080ipx-10G is utilized in high-bandwidth video switching applications. Professionals in broadcasting and streaming services implement this device for its capability to manage various network configurations and media streaming functions. The device features a web management interface where administrators can control settings related to video transmission and switch management. It runs on a PHP-based system with the webEASY SDK, which is integral for media professionals looking to integrate with existing network infrastructures. The Evertz SDVN 3080ipx-10G is vital for operations demanding reliable media distribution and intricate network assignments, particularly in studios and live events. This makes it a cornerstone for media distribution infrastructure, widely adopted due to its robust functionality and control features.
The vulnerability in question arises from arbitrary command injection via two exposed endpoints within the web management interface. These endpoints inadvertently allow remote unauthenticated users to execute commands as the root user, leading to a comprehensive security threat. With such vulnerabilities, attackers can perform unauthorized actions which may compromise system integrity and availability. This security flaw was identified due to improper input validation and insufficient authentication mechanisms on affected devices. Command injection weaknesses allow exploitation, granting malicious actors access to execute arbitrary commands, potentially altering system operations. Such vulnerabilities have substantial implications, particularly where sensitive media and network information is involved, necessitating immediate security audits.
Technically, the vulnerability is present in the PHP-based endpoints of the Evertz SDVN platform. Attackers can exploit these via crafted HTTP requests that bypass authentication checks. Specifically, a payload embedded in the query string is mishandled, granting elevated permissions that should not be accessible to unauthenticated users. By targeting the HTTP GET requests for specific PHP scripts, adversaries can gain unauthorized access. The vulnerable endpoints fail to adequately filter and sanitize incoming requests, facilitating command injection. This design flaw is further compounded by the exposed nature of the service, making it feasible for attackers to automate the exploitation of these vulnerabilities over the network.
Successful exploitation of this vulnerability could severely disrupt operations. Potential effects include unauthorized access to critical media control systems, interruption of media streams, or manipulation of streamed content. Such actions could impact service delivery, resulting in downtime or distorted media output. Financial and reputational damage can ensue from prolonged downtime and data breaches. Given that these systems often operate in real-time environments, any unplanned disruptions could significantly impair business operations. Additionally, access to internal networks and data poses serious threats to confidentiality and integrity.
