The vulnerability identified as CVE-2019-15565 represents a critical SQL injection flaw within the ICOMMKT connector module for PrestaShop platforms. This issue affects versions prior to 1.0.7 and specifically targets the icommktconnector.php file, which serves as the primary interface for communication between PrestaShop and the ICOMMKT service. The vulnerability stems from inadequate input validation and sanitization mechanisms within the module's codebase, creating an exploitable condition that allows malicious actors to inject arbitrary SQL commands into the database layer. The ICOMMKT connector is designed to facilitate data synchronization and communication between PrestaShop stores and external marketing platforms, making it a valuable target for attackers seeking to compromise e-commerce operations.
The technical implementation of this vulnerability occurs when user-supplied input is directly incorporated into SQL query construction without proper sanitization or parameterization. Attackers can manipulate the icommktconnector.php script by providing malicious input through parameters that are processed by the module's database interaction functions. This flaw aligns with CWE-89, which categorizes SQL injection vulnerabilities as a result of insufficient input validation in database queries. The vulnerability operates at the application level and can be exploited remotely, requiring no privileged access or authentication to the PrestaShop system. The attack vector typically involves manipulating URL parameters or form inputs that are passed to the vulnerable module, enabling unauthorized access to the underlying database infrastructure.
The operational impact of this vulnerability extends beyond simple data theft, as successful exploitation can lead to complete database compromise and potential system takeover. Attackers can execute arbitrary commands on the database server, potentially gaining access to sensitive customer information including personal details, payment data, and order histories. The vulnerability also poses risks to business continuity as it could enable data manipulation, deletion, or unauthorized modification of critical e-commerce data. Additionally, the compromise of customer information can result in significant regulatory compliance violations under data protection laws such as GDPR, potentially leading to substantial financial penalties and reputational damage. The vulnerability's presence in a widely used PrestaShop module increases the attack surface across numerous e-commerce platforms, making it particularly dangerous in a landscape where many small businesses may not have adequate security monitoring in place.
Organizations should prioritize immediate remediation by upgrading to ICOMMKT connector version 1.0.7 or later, which includes proper input validation and parameterized query implementations. Security measures should include implementing web application firewalls to monitor and filter suspicious database queries, conducting regular security audits of third-party modules, and establishing robust input validation protocols throughout the application stack. The vulnerability demonstrates the importance of maintaining up-to-date e-commerce platforms and modules, as well as implementing defense-in-depth strategies that include database access controls, query monitoring, and regular security assessments. From an ATT&CK framework perspective, this vulnerability maps to techniques involving SQL injection and privilege escalation, highlighting the need for comprehensive security controls that address both application-level and infrastructure-level threats. Organizations should also consider implementing database activity monitoring solutions to detect anomalous query patterns that may indicate exploitation attempts, while ensuring proper access controls and least-privilege principles are enforced for database connections.
