CVE-2019-13026 in OXID eShop
Summary
by MITRE
OXID eShop 6.0.x before 6.0.5 and 6.1.x before 6.1.4 allows SQL Injection via a crafted URL, leading to full access by an attacker. This includes all shopping cart options, customer data, and the database. No interaction between the attacker and the victim is necessary.

The vulnerability identified as CVE-2019-13026 represents a critical SQL injection flaw within the OXID eShop platform that affects versions prior to 6.0.5 and 6.1.4. This vulnerability exists in the web application's input validation mechanisms, specifically within the URL parameter handling functionality. The flaw allows malicious actors to inject arbitrary SQL commands through carefully crafted URLs, bypassing the application's normal security controls and authentication mechanisms. The vulnerability is particularly concerning because it operates without requiring any user interaction or engagement from the victim, making it an automated and highly dangerous threat vector.
The technical exploitation of this vulnerability stems from improper input sanitization within the OXID eShop's backend processing logic. When the application receives URL parameters, it fails to adequately validate or escape user-supplied data before incorporating it into SQL queries. This creates an environment where an attacker can inject malicious SQL payloads directly through URL structure, potentially manipulating the database queries to execute unauthorized operations. The vulnerability maps directly to CWE-89 which defines SQL injection as the insertion of malicious SQL code into input fields for execution by the database. The attack vector specifically targets the application's parameter parsing functionality, where user input flows directly into database operations without proper sanitization or parameterization.
The operational impact of this vulnerability extends far beyond simple data theft, as it grants attackers complete administrative access to the entire eShop platform. Successful exploitation allows unauthorized parties to view, modify, or delete all customer data, including personal information, payment details, and shopping cart contents. The database access encompasses full read-write capabilities, enabling attackers to manipulate product catalogs, alter pricing structures, modify customer accounts, and potentially install backdoors for persistent access. This level of compromise directly violates fundamental security principles and can result in significant financial losses, regulatory penalties, and reputational damage for affected organizations. The vulnerability's classification under the MITRE ATT&CK framework would likely map to T1071.004 for application layer protocol manipulation and T1046 for network service enumeration, as attackers would need to identify and exploit this specific SQL injection point.
Organizations affected by CVE-2019-13026 should immediately implement comprehensive mitigation strategies including updating to the patched versions 6.0.5 and 6.1.4, which contain proper input validation and parameterization fixes. Additionally, network-based intrusion detection systems should be configured to monitor for suspicious URL patterns and SQL injection attempts. Database access controls should be reviewed and strengthened with proper privilege separation, ensuring that application database accounts have minimal necessary permissions. Web application firewalls can provide additional protection layers, though they should not be relied upon as the sole defense mechanism. Regular security auditing and penetration testing should be conducted to identify similar vulnerabilities, while input validation should be implemented consistently across all application components. The vulnerability demonstrates the critical importance of proper parameterization and input validation in preventing SQL injection attacks, aligning with industry best practices outlined in OWASP Top Ten and NIST cybersecurity guidelines.
