CVE-2024-50802 identifies a SQL Injection vulnerability in AbanteCart version 1.4.0, specifically in the update() function located in public_html/admin/controller/responses/listing_grid/email_templates.php. The vulnerability arises due to improper sanitization of the id parameter, which is used in SQL queries without adequate validation or parameterization. An attacker with authenticated administrative privileges can exploit this flaw by injecting malicious SQL code through the id parameter, potentially leading to unauthorized data disclosure, modification, or deletion. The vulnerability affects the confidentiality of sensitive data primarily, with some impact on data integrity and availability. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:L) indicates that the attack can be performed remotely over the network with low complexity but requires high privileges and no user interaction. Although no public exploits have been reported yet, the presence of this vulnerability in a widely used e-commerce platform poses a tangible risk. The lack of an official patch at the time of publication necessitates immediate attention from administrators to implement compensating controls. The CWE-89 classification confirms this as a classic SQL Injection issue, a well-known and critical web application security problem.

The exploitation of this SQL Injection vulnerability can have severe consequences for organizations running AbanteCart 1.4.0. Attackers with administrative access could extract sensitive customer data, including personal and payment information, leading to privacy violations and regulatory non-compliance. The partial integrity impact means attackers might alter email templates or other database records, potentially disrupting business operations or enabling phishing attacks through manipulated communications. Availability impact, though limited, could result from database errors or crashes induced by malicious queries. Given that the vulnerability requires authenticated access, the threat is primarily to organizations with compromised or weak administrative credentials. The risk extends to e-commerce businesses globally, especially those relying on AbanteCart for online storefront management. The absence of known exploits in the wild suggests a window for proactive mitigation, but the medium severity rating underscores the need for timely remediation to avoid data breaches and reputational damage.

To mitigate CVE-2024-50802, organizations should first verify if they are running AbanteCart version 1.4.0 and restrict administrative access to trusted personnel only. Immediate steps include implementing strict input validation and sanitization for the id parameter in the affected update() function, ideally by applying parameterized queries or prepared statements to prevent SQL Injection. If an official patch becomes available, it should be applied promptly. In the absence of a patch, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the id parameter. Regularly audit administrative accounts for suspicious activity and enforce strong authentication mechanisms, such as multi-factor authentication, to reduce the risk of credential compromise. Additionally, monitor database logs for anomalous queries and maintain up-to-date backups to enable recovery in case of data corruption or loss. Educate administrators about the risks of SQL Injection and the importance of secure coding practices for any customizations.
