Description

Impact

A security vulnerability was discovered in the /api/v2/shop/adjustments/{id} endpoint, which retrieves order adjustments based on incremental integer IDs. The vulnerability allows an attacker to enumerate valid adjustment IDs and retrieve order tokens. Using these tokens, an attacker can access guest customer order details - sensitive guest customer information.

Patches

The issue is fixed in versions: 1.9.12, 1.10.16, 1.11.17, 1.12.19, 1.13.4 and above.
The /api/v2/shop/adjustments/{id} will always return 404 status.

Workarounds

Using YAML configuration:

Create config/api_platform/Adjustment.yaml file:

# config/api_platform/Adjustment.yaml

'%sylius.model.adjustment.class%':
    itemOperations:
        shop_get:
            controller: ApiPlatform\Core\Action\NotFoundAction
            read: false
            output: false

Or using XML configuration:

Note: This is the only way of disabling the vulnerable endpoint for Sylius 1.9, as YAML configuration is not supported in that version.

Copy the original configuration from vendor:

# create directory if it doesn't exist
mkdir -p config/api_platform

cp vendor/sylius/sylius/src/Sylius/Bundle/ApiBundle/Resources/config/api_resources/Adjustment.xml config/api_platform

And change the shop_get operation in copied config/api_platform/Adjustment.xml file:

<!-- config/api_platform/Adjustment.xml -->

...
<itemOperation name="shop_get">
    <attribute name="method">GET</attribute>
    <attribute name="path">/shop/adjustments/{id}</attribute>
    <attribute name="controller">ApiPlatform\Core\Action\NotFoundAction</attribute>
    <attribute name="read">false</attribute>
    <attribute name="output">false</attribute>
</itemOperation>
...

Update your API platform paths config if needed so the new configuration file is loaded:

# config/packages/api_platform.yaml
api_platform:
    mapping:
        paths:
          - '%kernel.project_dir%/vendor/sylius/sylius/src/Sylius/Bundle/ApiBundle/Resources/config/api_resources'
          ...
          - '%kernel.project_dir%/config/api_platform'

CVSS v4 base metrics

Exploitability Metrics
Attack Vector: This metric reflects the context by which vulnerability exploitation is possible. This metric value (and consequently the resulting severity) will be larger the more remote (logically, and physically) an attacker can be in order to exploit the vulnerable system. The assumption is that the number of potential attackers for a vulnerability that could be exploited from across a network is larger than the number of potential attackers that could exploit a vulnerability requiring physical access to a device, and therefore warrants a greater severity.
Attack Complexity: This metric captures measurable actions that must be taken by the attacker to actively evade or circumvent existing built-in security-enhancing conditions in order to obtain a working exploit. These are conditions whose primary purpose is to increase security and/or increase exploit engineering complexity. A vulnerability exploitable without a target-specific variable has a lower complexity than a vulnerability that would require non-trivial customization. This metric is meant to capture security mechanisms utilized by the vulnerable system.
Attack Requirements: This metric captures the prerequisite deployment and execution conditions or variables of the vulnerable system that enable the attack. These differ from security-enhancing techniques/technologies (ref Attack Complexity) as the primary purpose of these conditions is not to explicitly mitigate attacks, but rather, emerge naturally as a consequence of the deployment and execution of the vulnerable system.
Privileges Required: This metric describes the level of privileges an attacker must possess prior to successfully exploiting the vulnerability. The method by which the attacker obtains privileged credentials prior to the attack (e.g., free trial accounts), is outside the scope of this metric. Generally, self-service provisioned accounts do not constitute a privilege requirement if the attacker can grant themselves privileges as part of the attack.
User interaction: This metric captures the requirement for a human user, other than the attacker, to participate in the successful compromise of the vulnerable system. This metric determines whether the vulnerability can be exploited solely at the will of the attacker, or whether a separate user (or user-initiated process) must participate in some manner.
Vulnerable System Impact Metrics
Confidentiality: This metric measures the impact to the confidentiality of the information managed by the VULNERABLE SYSTEM due to a successfully exploited vulnerability. Confidentiality refers to limiting information access and disclosure to only authorized users, as well as preventing access by, or disclosure to, unauthorized ones.
Integrity: This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information. Integrity of the VULNERABLE SYSTEM is impacted when an attacker makes unauthorized modification of system data. Integrity is also impacted when a system user can repudiate critical actions taken in the context of the system (e.g. due to insufficient logging).
Availability: This metric measures the impact to the availability of the VULNERABLE SYSTEM resulting from a successfully exploited vulnerability. While the Confidentiality and Integrity impact metrics apply to the loss of confidentiality or integrity of data (e.g., information, files) used by the system, this metric refers to the loss of availability of the impacted system itself, such as a networked service (e.g., web, database, email). Since availability refers to the accessibility of information resources, attacks that consume network bandwidth, processor cycles, or disk space all impact the availability of a system.
Subsequent System Impact Metrics
Confidentiality: This metric measures the impact to the confidentiality of the information managed by the SUBSEQUENT SYSTEM due to a successfully exploited vulnerability. Confidentiality refers to limiting information access and disclosure to only authorized users, as well as preventing access by, or disclosure to, unauthorized ones.
Integrity: This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information. Integrity of the SUBSEQUENT SYSTEM is impacted when an attacker makes unauthorized modification of system data. Integrity is also impacted when a system user can repudiate critical actions taken in the context of the system (e.g. due to insufficient logging).
Availability: This metric measures the impact to the availability of the SUBSEQUENT SYSTEM resulting from a successfully exploited vulnerability. While the Confidentiality and Integrity impact metrics apply to the loss of confidentiality or integrity of data (e.g., information, files) used by the system, this metric refers to the loss of availability of the impacted system itself, such as a networked service (e.g., web, database, email).

Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Learn more on MITRE.

Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. Learn more on MITRE.
