CVE-2022-24748 is a medium-severity vulnerability affecting Shopware, an open commerce platform built on the Symfony PHP framework and Vue.js. The vulnerability arises from improper authentication due to insufficient API route checking in Shopware versions prior to 6.4.8.2. Specifically, it allows unauthorized users to modify customer data and create orders without possessing the necessary application permissions. This flaw is categorized under CWE-287 (Improper Authentication), indicating that the system fails to properly verify the identity or privileges of a user before granting access to sensitive operations. The vulnerability does not require user interaction or authentication, making it exploitable by unauthenticated attackers who can send crafted API requests to the affected Shopware platform. There are no known workarounds, and the only remediation is upgrading to version 6.4.8.2 or later, where the API route checking has been corrected to enforce proper permission validation. Although no known exploits have been reported in the wild, the nature of the vulnerability implies a significant risk to the confidentiality and integrity of customer data and transactional records within affected e-commerce environments. The vulnerability's exploitation could lead to unauthorized data manipulation, fraudulent order creation, and potential disruption of business operations.

For European organizations using Shopware versions prior to 6.4.8.2, this vulnerability poses a direct threat to the confidentiality and integrity of customer information and transactional data. Attackers exploiting this flaw could alter customer details, potentially leading to data breaches involving personally identifiable information (PII), which would have regulatory implications under GDPR. Unauthorized order creation could result in financial losses, inventory mismanagement, and reputational damage. The availability of the platform might also be indirectly affected if attackers manipulate orders or customer data to disrupt normal business processes. Given the widespread use of Shopware among European e-commerce businesses, especially small and medium enterprises (SMEs), the vulnerability could have a broad impact on the retail and online commerce sectors. Additionally, compromised customer trust and potential regulatory penalties could have long-term adverse effects on affected organizations.

The primary and only effective mitigation is to upgrade all Shopware platform instances to version 6.4.8.2 or later, where the improper authentication issue has been resolved. Organizations should prioritize patching vulnerable systems promptly. Beyond upgrading, it is recommended to implement strict network segmentation and firewall rules to limit external access to Shopware API endpoints, reducing the attack surface. Monitoring and logging API requests for unusual activity, such as unexpected customer data modifications or order creations, can help detect exploitation attempts early. Employing Web Application Firewalls (WAFs) with custom rules to block unauthorized API calls may provide additional protection until patches are applied. Regular security audits and penetration testing focused on API security should be conducted to identify similar weaknesses. Finally, organizations should review and enforce least privilege principles for API permissions and ensure that application-level access controls are correctly configured.
