CVE-2024-22406 is a critical SQL injection vulnerability (CWE-89) affecting Shopware, an open headless commerce platform widely used for e-commerce solutions. The vulnerability resides in the Shopware application API's search functionality, specifically in the 'aggregations' object where the 'name' field is improperly sanitized. This flaw allows attackers to inject malicious SQL commands through the 'name' parameter, enabling time-based SQL injection attacks. Exploiting this vulnerability does not require authentication or user interaction, and it can be triggered remotely over the network. The vulnerability impacts Shopware versions prior to 6.5.7.4, with patches and security plugins available for older 6.1 to 6.4 versions. The CVSS v3.1 base score is 9.3 (critical), reflecting the high impact on confidentiality due to potential data exposure, while integrity remains unaffected and availability impact is low. The vulnerability allows attackers to perform time-based blind SQL injection, which can be used to extract sensitive data from the backend database by measuring response delays. Although no known exploits are currently reported in the wild, the ease of exploitation and critical severity make this a significant threat to organizations using vulnerable Shopware versions. The recommended mitigation is to update to Shopware 6.5.7.4 or apply the provided security plugins for older versions to ensure full protection.

For European organizations using Shopware as their e-commerce platform, this vulnerability poses a severe risk to the confidentiality of customer data, including personal information and potentially payment details stored in the backend database. Successful exploitation could lead to unauthorized data disclosure, undermining customer trust and potentially violating GDPR regulations, which impose strict requirements on data protection and breach notification. Although the vulnerability does not directly affect data integrity or availability, the exposure of sensitive data can result in significant financial and reputational damage. Additionally, attackers could leverage the extracted information for further attacks such as identity theft or fraud. Given the widespread adoption of Shopware in Europe, especially among small and medium-sized enterprises in Germany, France, and the Netherlands, the threat landscape is considerable. Organizations failing to patch or mitigate this vulnerability risk regulatory penalties and loss of competitive advantage due to compromised customer trust.

1. Immediate upgrade to Shopware version 6.5.7.4, which contains the official patch addressing this SQL injection vulnerability. 2. For organizations unable to upgrade immediately, apply the official security plugins available for Shopware versions 6.1 through 6.4 to mitigate the vulnerability. 3. Conduct a thorough audit of all Shopware API endpoints, especially those exposing search and aggregation functionalities, to ensure no other injection vectors exist. 4. Implement Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the 'aggregations.name' parameter. 5. Monitor application logs for unusual query patterns or time delays indicative of time-based SQL injection attempts. 6. Enforce strict input validation and parameterized queries in any custom Shopware extensions or integrations to prevent similar injection flaws. 7. Educate development and security teams about secure coding practices related to database queries and API security. 8. Prepare an incident response plan focused on rapid detection and containment of SQL injection attacks, including data breach notification procedures compliant with GDPR.
