The vulnerability identified as CVE-2009-4891 represents a critical SQL injection flaw in CS-Cart version 2.0.0 Beta 3, specifically within the index.php file. This vulnerability manifests when the product_id parameter is passed through a products.view action, creating an exploitable entry point for remote attackers to execute arbitrary SQL commands against the underlying database system. The flaw stems from inadequate input validation and sanitization practices within the application's parameter handling mechanism, allowing malicious actors to manipulate database queries through crafted input data.
This SQL injection vulnerability falls under CWE-89, which specifically addresses improper neutralization of special elements used in SQL commands. The attack vector exploits the application's failure to properly escape or validate user-supplied input before incorporating it into database queries. When a remote attacker submits a malformed product_id parameter, the application processes this input directly into SQL execution without proper sanitization, enabling the injection of malicious SQL code that can be executed with the privileges of the database user account.
The operational impact of this vulnerability is severe and multifaceted, encompassing data integrity compromise, unauthorized access to sensitive information, and potential complete system takeover. Attackers can leverage this vulnerability to extract confidential data including user credentials, customer information, and business-sensitive records. The vulnerability also enables attackers to modify or delete database content, potentially leading to data corruption or complete database compromise. Furthermore, successful exploitation can provide attackers with a foothold for further lateral movement within the network infrastructure, as database credentials are often shared across multiple systems.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1071.004 which covers application layer protocol manipulation, specifically targeting web application vulnerabilities. The attack chain typically involves reconnaissance to identify the vulnerable parameter, crafting of malicious SQL payloads, and execution of the injection attack. The vulnerability's remote nature means that exploitation can occur from any location with internet access, making it particularly dangerous for publicly accessible web applications. Organizations using CS-Cart 2.0.0 Beta 3 should implement immediate mitigations including input validation, parameterized queries, and proper database access controls. The recommended remediation approach involves upgrading to a patched version of CS-Cart, implementing proper input sanitization, and establishing web application firewalls to detect and block malicious SQL injection attempts. Additionally, regular security assessments and database query monitoring should be implemented to prevent similar vulnerabilities from being introduced in future development cycles.
