CVE-2024-51992 — platform

Impact

This vulnerability is a method exposure issue (CWE-749: Exposed Dangerous Method or Function) in the Orchid Platform’s asynchronous modal functionality, affecting users of Orchid Platform version 8 through 14.42.x. Attackers could exploit this vulnerability to call arbitrary methods within the Screen class, leading to potential brute force of database tables, validation checks against user credentials, and disclosure of the server’s real IP address.

Patches

The issue has been patched in the latest release, version 14.43.0, released on November 6, 2024. Users should upgrade to version 14.43.0 or later to address this vulnerability.

Workarounds

If upgrading to version 14.43.0 is not immediately possible, you can mitigate the vulnerability by implementing middleware to intercept and validate requests to asynchronous modal endpoints, allowing only approved methods and parameters.

Example middleware:

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class PreventBruteForceOnAsyncRoute
{
    /**
     * Methods that are restricted from being invoked via the async route.
     */
    protected array $restrictedMethods = [
        'validate',
        'handle',
        '__invoke',
        'validateWith',
        'validateWithBag',
        'callAction',
    ];

    /**
     * Handle an incoming request.
     */
    public function handle(Request $request, Closure $next): Response
    {
        // Retrieve the current route from the request.
        /** @var \Illuminate\Routing\Route|null $route */
        $route = $request->route();

        // Allow requests to routes other than "platform.async".
        if ($route?->getName() !== 'platform.async') {
            return $next($request);
        }

        // Block requests attempting to invoke any of the restricted methods.
        if (in_array($route->parameter('method'), $this->restrictedMethods)) {
            abort(503, sprintf(
                'Access to the "%s" method is restricted.',
                $route->parameter('method')
            ));
        }

        // Continue request processing for other cases.
        return $next($request);
    }
}
