AVideo: Unauthenticated Information Disclosure via Disabled CLI Guard in install/test.php

Summary

The install/test.php diagnostic script has its CLI-only access guard disabled by commenting out the die() statement. The script remains accessible via HTTP after installation, exposing video viewer statistics including IP addresses, session IDs, and user agents to unauthenticated visitors.

Details

The disabled guard at install/test.php:5-7:

if (!isCommandLineInterface()) {
    //return die('Command Line only');
}

The script also enables verbose error reporting:

error_reporting(E_ALL);
ini_set('display_errors', '1');

It then queries VideoStatistic::getLastStatistics() and outputs the result via var_dump():

$resp = VideoStatistic::getLastStatistics(getVideos_id(), User::getId());
var_dump($resp);

The VideoStatistic object contains: ip (viewer IP address), session_id, user_agent, users_id, and JSON metadata. The display_errors=1 setting also leaks internal filesystem paths in any PHP warnings.

The install/ directory is not restricted by .htaccess (it only disables directory listing via Options -Indexes) and no web server rules block access to individual PHP files in this directory.

Proof of Concept

# Request viewer stats for video ID 1
curl "https://your-avideo-instance.com/install/test.php?videos_id=1"

Confirmed accessible on live AVideo instances (HTTP 200).

Impact

Unauthenticated disclosure of viewer IP addresses (PII under GDPR), session identifiers, and user agents. The enabled display_errors also reveals internal server paths on errors.

CWE: CWE-200 (Exposure of Sensitive Information)

Severity: Low

Recommended Fix

Uncomment the CLI guard at install/test.php:6 to restore the intended access restriction:

if (!isCommandLineInterface()) {
    return die('Command Line only');
}
