CVE-2025-14217 identifies a SQL injection vulnerability in the code-projects Currency Exchange System version 1.0, specifically in the /edittrns.php file. The vulnerability arises from improper sanitization of the 'ID' parameter, which an attacker can manipulate remotely without authentication or user interaction. By injecting crafted SQL statements, an attacker can execute arbitrary queries on the backend database, potentially extracting sensitive financial data, modifying transaction records, or disrupting service availability. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the vulnerability is remotely exploitable with low attack complexity and no privileges required, but with limited impact on confidentiality, integrity, and availability (each rated low). No patches are currently linked, and no exploits are reported in the wild, but a public exploit exists, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is used in financial environments to manage currency exchange transactions. The lack of authentication requirements and remote exploitability make this a significant threat vector for attackers targeting financial data integrity and confidentiality. Organizations using this system should urgently review their codebase, implement input validation, and apply prepared statements or parameterized queries to mitigate the risk.

For European organizations, this vulnerability poses a risk of unauthorized data access and manipulation within currency exchange transaction systems. Exploitation could lead to leakage of sensitive financial data, unauthorized modification of transaction records, and potential disruption of financial services. This can result in financial losses, regulatory non-compliance (e.g., GDPR violations due to data breaches), reputational damage, and operational downtime. Given the financial sector's critical role in Europe, such an attack could undermine trust in affected institutions and cause cascading effects in financial markets. Organizations relying on this software for transaction processing or financial reporting are particularly vulnerable. The medium severity rating suggests that while the impact is significant, it may not lead to full system compromise but still requires prompt remediation to avoid exploitation.

1. Immediately audit and sanitize all user inputs in the /edittrns.php file, especially the 'ID' parameter, using strict validation and allowlisting. 2. Refactor the code to use prepared statements or parameterized queries to prevent SQL injection. 3. Conduct a comprehensive code review of the entire application to identify and remediate similar injection flaws. 4. Monitor network traffic and application logs for suspicious SQL queries or unusual activity targeting the vulnerable endpoint. 5. Restrict database user permissions to the minimum necessary to limit the impact of potential exploitation. 6. If possible, isolate the vulnerable system behind a web application firewall (WAF) configured to detect and block SQL injection attempts. 7. Develop and test patches promptly and deploy them in all affected environments. 8. Educate developers and administrators on secure coding practices to prevent future injection vulnerabilities. 9. Implement regular vulnerability scanning and penetration testing focused on injection flaws. 10. Maintain an incident response plan to quickly address any exploitation attempts.
