CVE-2025-14216 identifies a SQL injection vulnerability in the code-projects Currency Exchange System version 1.0, specifically in the /viewserial.php endpoint. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is directly used in SQL queries. This allows an unauthenticated remote attacker to inject arbitrary SQL code, potentially enabling unauthorized access to sensitive database information, data manipulation, or disruption of service. The vulnerability does not require any user interaction or privileges, making it easier to exploit remotely. The CVSS 4.0 base score is 6.9 (medium), reflecting the network attack vector, low complexity, no authentication, and partial impact on confidentiality, integrity, and availability. Although no exploits are currently reported in the wild, the public disclosure increases the likelihood of future exploitation attempts. The affected product is a currency exchange system, which typically handles sensitive financial data, increasing the risk profile. The lack of available patches or mitigations from the vendor necessitates immediate defensive measures by users. The vulnerability highlights the critical need for secure coding practices such as input validation and use of parameterized queries to prevent SQL injection attacks.

For European organizations, especially those in the financial sector or providing currency exchange services, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of sensitive financial data, customer information, or transaction records, undermining confidentiality. Integrity could be compromised through unauthorized modification or deletion of data, potentially affecting financial calculations and reporting. Availability might be impacted if attackers execute destructive SQL commands or cause database corruption, leading to service outages. Given the remote and unauthenticated nature of the attack, threat actors could exploit this vulnerability at scale, targeting multiple organizations. This could result in regulatory penalties under GDPR due to data breaches, reputational damage, and financial losses. The medium severity score suggests moderate but non-trivial risk, warranting prompt attention to prevent escalation. Organizations relying on this software without timely patches are particularly vulnerable to targeted attacks or opportunistic exploitation.

1. Immediately audit all instances of the code-projects Currency Exchange System version 1.0 to identify affected deployments. 2. Implement input validation and sanitization on the 'ID' parameter in /viewserial.php to reject or properly escape malicious input. 3. Refactor database queries to use parameterized statements or prepared queries to eliminate direct injection vectors. 4. Deploy Web Application Firewalls (WAFs) with rules targeting SQL injection patterns specific to this vulnerability as a temporary protective measure. 5. Monitor database logs and application logs for unusual query patterns or errors indicative of injection attempts. 6. Restrict database user permissions to the minimum necessary to limit potential damage if exploited. 7. Engage with the vendor or community to obtain or develop official patches or updates addressing this vulnerability. 8. Conduct security awareness training for developers to prevent similar vulnerabilities in future releases. 9. Consider isolating or segmenting the vulnerable application within the network to reduce exposure. 10. Prepare incident response plans to quickly address potential exploitation events.
