CVE-2024-33269 is a critical SQL Injection vulnerability identified in the Prestaddons flashsales plugin, version 1.9.7 and earlier. The vulnerability resides in the FsModel::getFlashSales method, which fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows an unauthenticated attacker to inject arbitrary SQL commands remotely, potentially manipulating the backend database. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The CVSS v3.1 base score is 9.8, reflecting the ease of exploitation (network vector, no privileges or user interaction required) and the severe impact on confidentiality, integrity, and availability. Successful exploitation could lead to unauthorized data disclosure, modification, or deletion, and possibly full system compromise if the database controls critical application logic or authentication data. As of the publication date, no patches or official fixes have been released, and no public exploits have been observed in the wild. This vulnerability primarily affects e-commerce websites using the Prestaddons flashsales plugin, which is a popular add-on for Prestashop platforms. Given the critical nature and the lack of mitigations, attackers could weaponize this vulnerability quickly once exploit code becomes available.

The impact of CVE-2024-33269 is severe for organizations running Prestaddons flashsales on their e-commerce platforms. Exploitation can lead to unauthorized access to sensitive customer data, including personal and payment information, resulting in data breaches and regulatory non-compliance. Attackers could alter or delete sales data, disrupt business operations, or escalate privileges within the application or underlying infrastructure. The vulnerability’s ease of exploitation without authentication or user interaction increases the risk of widespread attacks. This could damage brand reputation, cause financial losses, and lead to legal liabilities. Organizations relying on this plugin for flash sales and promotions are particularly vulnerable to operational disruptions and data integrity issues. The absence of a patch means organizations must rely on immediate mitigation strategies to reduce exposure until an official fix is available.

1. Immediately audit all Prestaddons flashsales plugin installations and identify affected versions (1.9.7 and earlier). 2. If possible, disable or remove the flashsales plugin temporarily to eliminate the attack surface until a patch is released. 3. Implement Web Application Firewall (WAF) rules specifically targeting SQL injection patterns against the FsModel::getFlashSales endpoint or related URLs. 4. Employ strict input validation and parameterized queries in custom code if modifications are possible. 5. Monitor web server and database logs for unusual or suspicious SQL queries indicative of exploitation attempts. 6. Restrict database user permissions to the minimum necessary to limit the impact of potential injection attacks. 7. Stay alert for official patches or updates from Prestaddons and apply them immediately upon release. 8. Conduct penetration testing focused on SQL injection vectors to verify the effectiveness of mitigations. 9. Educate development and security teams about this vulnerability and the importance of secure coding practices to prevent similar issues.
