CVE-2025-50972 is a critical SQL Injection vulnerability identified in AbanteCart version 1.4.2. This vulnerability allows unauthenticated attackers to execute arbitrary SQL commands against the backend database by manipulating the 'tmpl_id' parameter in the 'index.php' script. The vulnerability is exploitable without requiring any authentication or user interaction, significantly increasing the risk of exploitation. Three distinct exploitation techniques have been demonstrated: error-based SQL injection using a crafted FLOOR() function payload, time-based blind SQL injection leveraging the SLEEP() function to infer data, and UNION-based SQL injection to extract arbitrary data from the database. These methods enable attackers to retrieve sensitive information, modify database contents, or potentially escalate privileges within the application or underlying system. The absence of a CVSS score indicates that this vulnerability is newly disclosed, but the technical details and attack vectors suggest a high severity level. The lack of available patches or mitigations at the time of publication further exacerbates the risk. AbanteCart is an open-source e-commerce platform used by various online retailers, and exploitation of this vulnerability could lead to data breaches, financial fraud, and loss of customer trust.

For European organizations using AbanteCart 1.4.2, this vulnerability poses a significant threat to the confidentiality, integrity, and availability of their e-commerce platforms. Successful exploitation could result in unauthorized access to customer data, including personally identifiable information (PII) and payment details, potentially violating GDPR requirements and leading to substantial regulatory penalties. Data manipulation or deletion could disrupt business operations, causing financial losses and reputational damage. Additionally, attackers could leverage the vulnerability to implant malicious code or backdoors, facilitating further attacks such as ransomware or supply chain compromises. Given the critical role of e-commerce in European markets, especially for SMEs relying on platforms like AbanteCart, the impact could be widespread. The vulnerability's unauthenticated nature means attackers can scan and exploit vulnerable instances remotely, increasing the likelihood of attacks targeting European businesses.

European organizations should immediately assess their use of AbanteCart 1.4.2 and related versions for the presence of the vulnerable 'tmpl_id' parameter in 'index.php'. Until an official patch is released, organizations should implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the 'tmpl_id' parameter, including patterns related to FLOOR(), SLEEP(), and UNION SQL commands; 2) Conduct thorough input validation and sanitization on all user-supplied parameters, especially 'tmpl_id', to reject unexpected or malicious input; 3) Restrict database user privileges to the minimum necessary to limit the impact of potential SQL injection; 4) Monitor application logs and database queries for anomalous activity indicative of SQL injection attempts; 5) Consider temporarily disabling or restricting access to vulnerable endpoints if feasible; 6) Stay alert for official patches or updates from AbanteCart and apply them promptly upon release; 7) Educate development and security teams about secure coding practices to prevent similar vulnerabilities in the future.
