CVE-2025-11608 identifies a SQL injection vulnerability in the code-projects E-Banking System version 1.0, specifically within the /register.php file's POST parameter handler that processes username and password inputs. The vulnerability arises from improper sanitization or validation of these input parameters, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This can lead to unauthorized database queries, enabling attackers to read, modify, or delete sensitive banking data, bypass authentication mechanisms, or escalate privileges within the application. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low complexity and no privileges or user interaction needed, but with limited impact on confidentiality, integrity, and availability. No patches or fixes have been published yet, and no known exploits are currently observed in the wild, but public disclosure increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, suggesting that upgrading or applying vendor patches when available is critical. The lack of secure coding practices in input handling highlights a significant risk for financial institutions relying on this software, as SQL injection is a well-known attack vector that can lead to severe data breaches and operational disruption.

For European organizations, particularly banks and financial institutions using code-projects E-Banking System 1.0, this vulnerability poses a significant risk to sensitive customer data and transactional integrity. Exploitation could lead to unauthorized access to user credentials, financial records, and personal information, resulting in financial fraud, identity theft, and regulatory non-compliance with GDPR and other data protection laws. The integrity of banking operations could be compromised, potentially causing service outages or manipulation of transaction data. The reputational damage and financial penalties from a breach could be substantial. Given the remote exploitability without authentication, attackers could target multiple institutions simultaneously, increasing the threat landscape. The medium severity rating suggests that while the vulnerability is serious, it may require some attacker skill or conditions to fully exploit, but the impact on confidentiality and integrity remains significant. European regulators and cybersecurity agencies would likely prioritize mitigation efforts to protect critical financial infrastructure.

Organizations should immediately audit their deployment of code-projects E-Banking System version 1.0 to identify affected instances. Until a vendor patch is available, implement strict input validation and sanitization on all user-supplied data, especially the username and password fields in /register.php. Employ parameterized queries or prepared statements to prevent SQL injection. Use Web Application Firewalls (WAFs) with rules designed to detect and block SQL injection attempts targeting the vulnerable endpoint. Conduct thorough code reviews and penetration testing focused on input handling and authentication modules. Monitor logs for unusual database queries or failed login attempts indicative of exploitation attempts. Segregate and limit database privileges for the application to minimize potential damage. Prepare incident response plans specific to SQL injection attacks. Engage with the vendor for timely patch releases and apply updates promptly once available. Additionally, raise awareness among development teams about secure coding practices to prevent similar vulnerabilities.
