Description

Internal exception message exposure for login action

Impact

Exception messages from internal exceptions (like database exception) are wrapped by \Symfony\Component\Security\Core\Exception\AuthenticationServiceException and propagated through the system to UI. Therefore, some internal system information may leak and be visible to the customer.

A validation message with the exception details will be presented to the user when one will try to log into the shop.

Workarounds

The src/Sylius/Bundle/UiBundle/Resources/views/Security/_login.html.twig file should be overridden and lines https://github.com/Sylius/Sylius/blob/1.4/src/Sylius/Bundle/UiBundle/Resources/views/Security/_login.html.twig#L13-L17 should be replaced with

        {% if last_error %}
            <div class="ui left aligned basic segment">
                {{ messages.error(last_error.messageKey) }}
            </div>
        {% endif %}

The messageKey field should be used instead of the message.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
