CVE-2025-12215 identifies a SQL injection vulnerability in projectworlds Online Shopping System version 1.0, located in the /login_submit.php file. The vulnerability arises from improper sanitization of the 'keywords' parameter, which can be manipulated by remote attackers to inject malicious SQL commands. This injection flaw allows attackers to execute arbitrary SQL queries on the backend database, potentially leading to unauthorized data disclosure, data modification, or even full system compromise depending on the database privileges. The attack vector is network-based, requiring no authentication or user interaction, which significantly lowers the barrier for exploitation. The CVSS 4.0 score of 6.9 (medium severity) reflects the moderate impact on confidentiality, integrity, and availability, with an exploitability rating indicating low complexity and no privileges required. Although no active exploitation has been reported, the public availability of exploit code increases the likelihood of attacks. The vulnerability affects only version 1.0 of the product, which is an online shopping system commonly used by small to medium-sized e-commerce websites. The absence of official patches or vendor advisories necessitates immediate mitigation efforts by users. This vulnerability exemplifies a classic injection flaw that can be mitigated by adopting secure coding practices such as prepared statements and rigorous input validation.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive customer data, including personal and payment information, resulting in data breaches and regulatory non-compliance under GDPR. Integrity of transaction data could be compromised, leading to fraudulent orders or financial losses. Availability of the e-commerce platform may be disrupted if attackers execute destructive SQL commands or cause database corruption. The reputational damage and potential legal consequences could be significant, especially for retailers with large customer bases. Small and medium enterprises using projectworlds Online Shopping System may lack robust security teams, increasing their risk exposure. The remote and unauthenticated nature of the attack vector means that attackers can target these systems at scale, potentially affecting multiple European countries with active e-commerce sectors. The medium severity rating suggests that while the impact is serious, it may not lead to full system takeover without additional vulnerabilities or misconfigurations.

1. Immediate code review and remediation of the /login_submit.php file to implement parameterized queries or prepared statements for all database interactions involving the 'keywords' parameter. 2. Implement strict input validation and sanitization to reject or neutralize malicious input before it reaches the database layer. 3. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the vulnerable parameter. 4. Conduct thorough security testing, including automated scanning and manual penetration testing, to identify any other injection points. 5. Monitor logs for unusual database queries or repeated failed login attempts that may indicate exploitation attempts. 6. If patching is not immediately possible, consider temporarily disabling or restricting access to the vulnerable functionality. 7. Educate development teams on secure coding practices to prevent recurrence of injection flaws. 8. Maintain regular backups of databases to enable recovery in case of data corruption or loss. 9. Engage with the vendor or community to obtain or develop official patches or updates for the affected product version.
