# CVE-2026-82504: VITEC EZ TV Platform Server Unauthenticated File Upload via UploadHandler.ashx

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

VITEC EZ TV Platform Server before 8.5.0 contains an unrestricted file upload vulnerability in the upload handler that allows unauthenticated remote attackers to upload arbitrary files by supplying a target filename in the X-FILENAME request header with no authentication or file type validation required. Attackers can upload a malicious ASPX file directly to the web-accessible uploads directory, where it is immediately executable by the web server, achieving remote code execution in the context of the web server process. Patches are available for versions 8.3.0, 8.3.1, 8.4.0, and 8.4.1. Users running releases prior to 8.3.0 should upgrade to 8.5.0+.

## Remediation

- fix: All customers on an EZ TV Platform Server Version prior to 8.5.0 should contact the Vitec Helpdesk immediately to schedule patch or upgrade. (source: CNA: VulnCheck)
