Insufficient Session Expiration in Sylius

Impact

The reset password token was not set to null after the password was changed. This is causing behaviour in which the same token can be used several times, so it can result in a leak of the existing token and an unauthorised password change.

Patches

The issue is fixed in versions: 1.10.11, 1.11.2 and above

Workarounds

You have to overwrite your Sylius\Bundle\ApiBundle\CommandHandler\ResetPasswordHandler class using this code:

<?php
declare(strict_types=1);

namespace App\CommandHandler\Account;

use Sylius\Bundle\ApiBundle\Command\Account\ResetPassword;
use Sylius\Component\Core\Model\ShopUserInterface;
use Sylius\Component\Resource\Metadata\MetadataInterface;
use Sylius\Component\User\Repository\UserRepositoryInterface;
use Sylius\Component\User\Security\PasswordUpdaterInterface;
use Symfony\Component\Messenger\Handler\MessageHandlerInterface;
use Webmozart\Assert\Assert;

final class ResetPasswordHandler implements MessageHandlerInterface
{
    private UserRepositoryInterface $userRepository;
    private MetadataInterface $metadata;
    private PasswordUpdaterInterface $passwordUpdater;

    public function __construct(
        UserRepositoryInterface $userRepository,
        MetadataInterface $metadata,
        PasswordUpdaterInterface $passwordUpdater
    ) {
        $this->userRepository = $userRepository;
        $this->metadata = $metadata;
        $this->passwordUpdater = $passwordUpdater;
    }

    public function __invoke(ResetPassword $command): void
    {
        /** @var ShopUserInterface|null $user */
        $user = $this->userRepository->findOneBy(['passwordResetToken' => $command->resetPasswordToken]);

        Assert::notNull($user, 'No user found with reset token: ' . $command->resetPasswordToken);

        $resetting = $this->metadata->getParameter('resetting');
        $lifetime = new \DateInterval($resetting['token']['ttl']);

        if (!$user->isPasswordRequestNonExpired($lifetime)) {
            throw new \InvalidArgumentException('Password reset token has expired');
        }

        if ($command->resetPasswordToken !== $user->getPasswordResetToken()) {
            throw new \InvalidArgumentException('Password reset token does not match.');
        }

        $user->setPlainPassword($command->newPassword);

        $this->passwordUpdater->updatePassword($user);
        $user->setPasswordResetToken(null);
    }
}

And register it in container:

App\CommandHandler\Account\ResetPasswordHandler:
    arguments:
        - '@sylius.repository.shop_user'
        - !service
              class: Sylius\Component\Resource\Metadata\MetadataInterface
              factory: [ '@sylius.resource_registry', 'get' ]
              arguments:
                    - 'sylius.shop_user'
                    - '@sylius.security.password_updater'
    tags:
        - { name: messenger.message_handler, bus: sylius.command_bus }
        - { name: messenger.message_handler, bus: sylius_default.bus }
