Title

WWBN AVideo has Unauthenticated FFmpeg Remote Server Status Disclosure via check.ffmpeg.json.php

Summary

WWBN AVideo is an open source video platform. In versions 26.0 and prior, the plugin/API/check.ffmpeg.json.php endpoint probes the FFmpeg remote server configuration and returns connectivity status without any authentication. All sibling FFmpeg management endpoints (kill.ffmpeg.json.php, list.ffmpeg.json.php, ffmpeg.php) require User::isAdmin().

GHSA-2VG4-RRX4-QCPQ

Vulnerability from github – Published: 2026-04-04 06:16 – Updated: 2026-04-07 14:20

Summary

AVideo: Unauthenticated FFmpeg Remote Server Status Disclosure via check.ffmpeg.json.php

Details

Summary

The plugin/API/check.ffmpeg.json.php endpoint probes the FFmpeg remote server configuration and returns connectivity status without any authentication. All sibling FFmpeg management endpoints (kill.ffmpeg.json.php, list.ffmpeg.json.php, ffmpeg.php) require User::isAdmin().

Details

The entire file at plugin/API/check.ffmpeg.json.php:

<?php
$configFile = __DIR__.'/../../videos/configuration.php';
require_once $configFile;
header('Content-Type: application/json');

$obj = testFFMPEGRemote();

die(json_encode($obj));

No User::isAdmin(), User::isLogged(), or any access control check exists.

Compare with sibling endpoints in the same directory: - kill.ffmpeg.json.php checks User::isAdmin() - list.ffmpeg.json.php checks User::isAdmin()

Proof of Concept

curl "https://your-avideo-instance.com/plugin/API/check.ffmpeg.json.php"

Returns information about whether the platform uses a standalone FFmpeg server and its current reachability.

Impact

Infrastructure reconnaissance revealing the encoding architecture. Limited direct impact but aids targeted attack planning.

Recommended Fix

Add an admin authentication check at plugin/API/check.ffmpeg.json.php:3, after require_once $configFile;:

if (!User::isAdmin()) {
    forbiddenPage('Admin only');
}

All sibling FFmpeg management endpoints (`kill.ffmpeg.json.php`, `list.ffmpeg.json.php`, `ffmpeg.php`) require `User::isAdmin()`.\n\n## Details\n\nThe entire file at `plugin/API/check.ffmpeg.json.php`:\n\n```php\n\u003c?php\n$configFile = __DIR__.\u0027/../../videos/configuration.php\u0027;\nrequire_once $configFile;\nheader(\u0027Content-Type: application/json\u0027);\n\n$obj = testFFMPEGRemote();\n\ndie(json_encode($obj));\n```\n\nNo `User::isAdmin()`, `User::isLogged()`, or any access control check exists.\n\nCompare with sibling endpoints in the same directory:\n- `kill.ffmpeg.json.php` checks `User::isAdmin()`\n- `list.ffmpeg.json.php` checks `User::isAdmin()`\n\n## Proof of Concept\n\n```bash\ncurl \"https://your-avideo-instance.com/plugin/API/check.ffmpeg.json.php\"\n```\n\nReturns information about whether the platform uses a standalone FFmpeg server and its current reachability.\n\n## Impact\n\nInfrastructure reconnaissance revealing the encoding architecture. Limited direct impact but aids targeted attack planning.\n\n## Recommended Fix\n\nAdd an admin authentication check at `plugin/API/check.ffmpeg.json.php:3`, after `require_once $configFile;`:\n\n```php\nif (!User::isAdmin()) {\n    forbiddenPage(\u0027Admin only\u0027);\n}\n```\n\n---\n*Found by [aisafe.io](https://aisafe.io)*",
