CVE-2017-12415 in eShop Community Edition
Summary
by MITRE
OXID eShop Community Edition before 6.0.0 RC2 (development), 4.10.x before 4.10.5 (maintenance), and 4.9.x before 4.9.10 (legacy), Enterprise Edition before 6.0.0 RC2 (development), 5.2.x before 5.2.10 (legacy), and 5.3.x before 5.3.5 (maintenance), and Professional Edition before 6.0.0 RC2 (development), 4.9.x before 4.9.10 (legacy) and 4.10.x before 4.10.5 (maintenance) allow remote attackers to hijack the cart session of a client via Cross-Site Request Forgery (CSRF) if the following pre-conditions are met: (1) the attacker knows which shop is presently used by the client, (2) the attacker knows the exact time when the customer will add product items to the cart, (3) the attacker knows which product items are already in the cart (has to know their article IDs), and (4) the attacker would be able to trick user into clicking a button (submit form) of an e-mail or remote site within the period of visiting the shop and placing an order.

This vulnerability represents a critical cross-site request forgery flaw in the OXID eShop platform that enables remote attackers to hijack user cart sessions and manipulate shopping cart contents. The vulnerability affects multiple versions across different product editions including Community, Enterprise, and Professional editions, with specific affected ranges spanning from version 4.9.x through 4.10.x and 5.2.x through 5.3.x releases. The flaw operates under specific pre-conditions that must be met for successful exploitation, requiring attackers to possess detailed knowledge about the target user's shopping behavior and timing. The technical implementation involves the absence of proper CSRF protection mechanisms in the cart session handling functionality, allowing malicious actors to craft requests that appear legitimate to the eShop server while being initiated by the victim's browser. This vulnerability directly maps to CWE-352, which classifies cross-site request forgery as a weakness that allows attackers to perform actions on behalf of authenticated users without their knowledge or consent. The operational impact is significant as attackers can manipulate the contents of user shopping carts, potentially leading to unauthorized purchases, inventory discrepancies, and financial loss for both customers and merchants. The vulnerability's exploitation requires precise timing and knowledge of the target user's session state, making it particularly dangerous in scenarios where attackers can predict user behavior patterns or have access to information about ongoing shopping sessions. The attack vector involves tricking users into clicking malicious links or submitting forms from email communications or compromised websites, leveraging the trust relationship between the user's browser and the eShop application. This vulnerability exposes a fundamental flaw in the session management and request validation mechanisms of the eShop platform, where the application fails to properly authenticate and validate the origin of cart modification requests. The impact extends beyond simple cart manipulation to potentially compromise the integrity of the entire shopping process, affecting order processing, payment handling, and inventory management systems. Organizations using affected versions of OXID eShop should prioritize immediate remediation through version upgrades to mitigate this CSRF vulnerability and protect their customers' shopping experiences. The remediation process should include implementing proper CSRF tokens in all cart-related requests and ensuring that session management mechanisms properly validate the authenticity of user-initiated actions. This vulnerability aligns with ATT&CK technique T1531, which involves the use of unauthorized commands to manipulate application functionality, and demonstrates how web application vulnerabilities can be leveraged to compromise user sessions and data integrity. The security implications of this vulnerability underscore the importance of implementing comprehensive CSRF protection mechanisms in e-commerce platforms and highlight the critical need for regular security assessments of web applications handling sensitive user data and financial transactions.
