CVE-2022-24742

Workarounds

The application must strictly redirect to the login page even when the browser back button is pressed. Another possibility is to set more strict cache policies for restricted content (like no-store). It can be achieved with the following class:

<?php

declare(strict_types=1);

namespace App\EventListener;

use App\SectionResolver\ShopCustomerAccountSubSection;
use Sylius\Bundle\AdminBundle\SectionResolver\AdminSection;
use Sylius\Bundle\CoreBundle\SectionResolver\SectionProviderInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\ResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;

final class CacheControlSubscriber implements EventSubscriberInterface
{
    /** @var SectionProviderInterface */
    private $sectionProvider;

    public function __construct(SectionProviderInterface $sectionProvider)
    {
        $this->sectionProvider = $sectionProvider;
    }

    public static function getSubscribedEvents(): array
    {
        return [
            KernelEvents::RESPONSE => 'setCacheControlDirectives',
        ];
    }

    public function setCacheControlDirectives(ResponseEvent $event): void
    {
        if (
            !$this->sectionProvider->getSection() instanceof AdminSection &&
            !$this->sectionProvider->getSection() instanceof ShopCustomerAccountSubSection
        ) {
            return;
        }

        $response = $event->getResponse();

        $response->headers->addCacheControlDirective('no-cache', true);
        $response->headers->addCacheControlDirective('max-age', '0');
        $response->headers->addCacheControlDirective('must-revalidate', true);
        $response->headers->addCacheControlDirective('no-store', true);
    }
}

After that register service in the container:

services:
    App\EventListener\CacheControlSubscriber:
        arguments: ['@sylius.section_resolver.uri_based_section_resolver']
        tags:
            - { name: kernel.event_subscriber, event: kernel.response }

The code above requires changes in ShopUriBasedSectionResolver in order to work. To backport mentioned logic, you need to replace the Sylius\Bundle\ShopBundle\SectionResolver\ShopUriBasedSectionResolver class with:

<?php

declare(strict_types=1);

namespace App\SectionResolver;

use Sylius\Bundle\CoreBundle\SectionResolver\SectionInterface;
use Sylius\Bundle\CoreBundle\SectionResolver\UriBasedSectionResolverInterface;
use Sylius\Bundle\ShopBundle\SectionResolver\ShopSection;

final class ShopUriBasedSectionResolver implements UriBasedSectionResolverInterface
{
    /** @var string */
    private $shopCustomerAccountUri;

    public function __construct(string $shopCustomerAccountUri = 'account')
    {
        $this->shopCustomerAccountUri = $shopCustomerAccountUri;
    }

    public function getSection(string $uri): SectionInterface
    {
        if (str_contains($uri, $this->shopCustomerAccountUri)) {
            return new ShopCustomerAccountSubSection();
        }

        return new ShopSection();
    }
}

services:
    sylius.section_resolver.shop_uri_based_section_resolver:
        class: App\SectionResolver\ShopUriBasedSectionResolver
        tags:
            - { name: sylius.uri_based_section_resolver, priority: -10 }

You also need to define a new subsection for the Customer Account that is used in the above services:

<?php

declare(strict_types=1);

namespace App\SectionResolver;

use Sylius\Bundle\ShopBundle\SectionResolver\ShopSection;

class ShopCustomerAccountSubSection extends ShopSection
{
}

Any other user can view the data if the browser tab remains open after logging out. Once someone logs out and leaves the browser open, the potential attacker may use the back button to see the content exposed on given screens. No action may be performed though, and any website refresh will block further reads. It may, however, lead to a data leak, like for example customer details, payment gateway configuration, etc.- but only if these were pages checked by the administrator.

This vulnerability requires full access to the computer to take advantage of it.

CVE-2022-24742 has a CVSS score of 5.0 (Medium). The vector is requires local access, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.9.10, 1.10.11, 1.11.2); upgrading removes the vulnerable code path.

Kodem intelligence

The issue is fixed in versions: 1.9.10, 1.10.11, 1.11.2 and above.

1. What is CVE-2022-24742? CVE-2022-24742 is a medium-severity security vulnerability in sylius/sylius (composer), affecting versions < 1.9.10. It is fixed in 1.9.10, 1.10.11, 1.11.2.
2. How severe is CVE-2022-24742? CVE-2022-24742 has a CVSS score of 5.0 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of sylius/sylius are affected by CVE-2022-24742? sylius/sylius (composer) versions < 1.9.10 is affected.
4. Is there a fix for CVE-2022-24742? Yes. CVE-2022-24742 is fixed in 1.9.10, 1.10.11, 1.11.2. Upgrade to this version or later.
5. Is CVE-2022-24742 exploitable, and should I be worried? Whether CVE-2022-24742 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2022-24742 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2022-24742?
   • Upgrade sylius/sylius to 1.9.10 or later
   • Upgrade sylius/sylius to 1.10.11 or later
   • Upgrade sylius/sylius to 1.11.2 or later
