VITEC EZ TV Platform Server Unauthenticated File Upload RCE.

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-82504

The vulnerability affects an IPTV and digital signage platform server. Such platforms are commonly deployed as web-based management interfaces or media distribution portals, which are frequently exposed to the network to facilitate remote access for administrative tasks or content management. The vulnerability allows unauthenticated file uploads, consistent with an internet-accessible web application service.

Horizon Alert

Summary of the vulnerability and why it matters

This critical vulnerability allows unauthenticated remote attackers to upload and execute arbitrary files on VITEC EZ TV Platform servers, potentially leading to unauthorized code execution. The issue lies in an unrestricted file upload vulnerability within the upload handler, which lacks proper authentication and file type validation.

Unrestricted file upload allows remote code execution.

Attack Path

How an attacker could exploit the issue

Attackers can reach and trigger this vulnerability by exploiting an unprotected file upload feature within the VITEC EZ TV Platform Server. This feature allows unauthenticated remote attackers to upload arbitrary files by manipulating the X-FILENAME request header. By uploading a malicious ASPX file to the web-accessible uploads directory, an attacker can achieve remote code execution on the server.

Unauthenticated remote access required.
Uploading malicious files via X-FILENAME header.
Remote code execution in web server context.

Live Threat

Current exploitation, exposure, and threat context

Frequently asked questions

What is the VITEC EZ TV Platform Server?

It is an enterprise-grade solution designed for IPTV distribution and digital signage management. Organizations use this platform to centrally control, stream, and deliver video content across their networks. Because it acts as a web-based hub for media and management tasks, it often serves as the backbone for an organization's internal or public-facing video infrastructure.

What does CVE-2026-82504 mean by unrestricted file upload?

This vulnerability, classified as CWE-434 (Unrestricted Upload of File with Dangerous Type) and CWE-306 (Missing Authentication for Critical Function), describes a system that fails to verify the identity of a user or the content of an uploaded file. Because the platform does not restrict what is sent to its upload handler, an attacker can bypass security controls to place malicious scripts directly onto the server where they can be run as code.

How is this vulnerability triggered by an attacker?

An attacker triggers the flaw by sending a specifically crafted network request to the server's upload handler. By manipulating the X-FILENAME header, they can force the server to save a file—such as an ASPX script—into a web-accessible directory. Importantly, standard usage of the platform for legitimate content delivery does not trigger this; the bug requires the deliberate submission of malicious files designed to bypass the platform's intended functions.

Is my VITEC EZ TV server at risk?

Halo Surface Signal indicates that because this platform is typically deployed as a web-based management interface, it is frequently accessible over the network to support remote administrative tasks. If your server instance is configured to be reachable via the internet, it is at higher risk of being targeted by unauthenticated remote attackers who can interact with the vulnerable upload handler.

How should I respond to this security advisory?

Prioritize identifying all active VITEC EZ TV Platform Server instances within your environment and confirming their version numbers. If you are running a version prior to 8.5.0, evaluate your patching options immediately. Versions 8.3.0 through 8.4.1 have specific updates available, while all older releases require an upgrade to 8.5.0 or higher to eliminate the security gap.
