Comprehensive Technical Analysis of EUVD-2024-0406

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2024-0406 affects the Shopware open headless commerce platform, specifically within the application API's search functionality. The 'name' field in the "aggregations" object is susceptible to SQL injection, which can be exploited using time-based SQL queries. This vulnerability has a CVSS base score of 9.3, indicating a critical severity level. The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L) highlights the following characteristics:

• Attack Vector (AV:N): Network, meaning the vulnerability is exploitable remotely.
• Attack Complexity (AC:L): Low, indicating that the attack does not require special conditions.
• Privileges Required (PR:N): None, meaning no privileges are required to exploit the vulnerability.
• User Interaction (UI:N): None, indicating that no user interaction is required.
• Scope (S:C): Changed, meaning the vulnerability can affect resources beyond the security scope managed by the security authority.
• Confidentiality (C:H): High, indicating a complete loss of confidentiality.
• Integrity (I:N): None, indicating no impact on integrity.
• Availability (A:L): Low, indicating a reduced performance or interruptions in resource availability.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is through the Shopware application API, specifically targeting the search functionality. An attacker can inject malicious SQL code into the 'name' field of the "aggregations" object. Time-based SQL injection techniques can be used to extract information by observing the time delay in responses. This method allows attackers to:

• Extract sensitive data from the database.
• Perform unauthorized actions within the database.
• Potentially escalate privileges or gain further access to the system.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of Shopware:

• Shopware 6.1
• Shopware 6.2
