Summary
VITEC EZ TV Platform Server contains a file upload flaw in its upload handler that lets an unauthenticated attacker on the network upload arbitrary files, including malicious ASPX files that the web server can run, which can lead to remote code execution. The attack requires no login or user action.
Original description
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+.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-82504 (VITEC EZ TV Platform Server Unauthenticated File Upload via UploadHandler.ashx), using the cve.now data below.
Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.
What cve.now has for CVE-2026-82504 (entry last updated 2026-11-13):
Affected:
- VITEC EZ TV Platform Server: fixed in 8.5.0
Fixed versions: 8.5.0.
Conditions (all must be true for the bug to be hit):
- EZ TV Platform Server releases before 8.5.0 (source: https://www.vulncheck.com/advisories/vitec-ez-tv-platform-server-unauthenticated-file-upload-via-uploadhandler-ashx)
- The web server executes uploaded ASPX files from the web-accessible uploads directory (source: https://www.vulncheck.com/advisories/vitec-ez-tv-platform-server-unauthenticated-file-upload-via-uploadhandler-ashx)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, no login, no user action.
CISA KEV: CVE-2026-82504 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-82504 only. If you also check another CVE, look up its own KEV status; never assume it from this one.
How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.
Verify against the linked advisories before concluding, and cite the date you read each one:
- https://www.vitec.com/dl/vitec-ez-tv-platform-datasheet
- https://www.vulncheck.com/advisories/vitec-ez-tv-platform-server-unauthenticated-file-upload-via-uploadhandler-ashx
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.
Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-82504
Is CVE-2026-82504 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The server accepts file uploads without adequate restriction, so a malicious ASPX file can be placed directly in the web-accessible uploads directory. The web server then executes that file, which allows remote code execution in the context of the web server process.Source: vulncheck.com
Which versions are affected by CVE-2026-82504?
EZ TV Platform Server: before 8.5.0.Source: cve.now feed data
Am I affected, and how do I check?
EZ TV Platform Server releases before 8.5.0 are affected, in setups where the web server executes uploaded ASPX files from the web-accessible uploads directory. To check, compare the installed version of EZ TV Platform Server with 8.5.0 and confirm whether ASPX files in that uploads directory are executed by the web server.Source: vulncheck.com
How do I fix CVE-2026-82504?
Upgrade to a fixed version: 8.5.0. The vendor's advisory also recommends 8.3.0 or 8.3.1 or 8.4.0 or 8.4.1 or later.Source: cve.now feed data, vulncheck.com
