CVE-2025-13449 is a SQL injection vulnerability identified in the code-projects Online Shop Project version 1.0. The flaw exists in the /login.php script, where the Password argument is not properly sanitized or parameterized, allowing attackers to inject arbitrary SQL queries remotely without requiring authentication or user interaction. This vulnerability can be exploited by crafting malicious input that manipulates the backend SQL query logic, potentially enabling attackers to bypass authentication, extract sensitive user credentials, modify or delete database records, or disrupt service availability. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity, with the vector indicating network attack vector, low attack complexity, no privileges or user interaction needed, and limited impact on confidentiality, integrity, and availability. Although no active exploits have been reported in the wild, the public disclosure of exploit code increases the likelihood of exploitation attempts. The affected product is an e-commerce platform, making it a high-value target for attackers seeking financial data or customer information. The lack of patches or official fixes at the time of publication necessitates immediate mitigation efforts by users of the software. The vulnerability highlights the critical need for secure coding practices such as input validation and use of prepared statements to prevent injection attacks.

For European organizations using the code-projects Online Shop Project 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of customer and business data. Successful exploitation could lead to unauthorized access to user accounts, exposure of sensitive personal and payment information, and potential financial fraud. Data integrity could be compromised by unauthorized modification or deletion of database records, impacting order processing and inventory management. Availability may also be affected if attackers disrupt database operations or cause application crashes. The reputational damage and regulatory consequences under GDPR for data breaches could be severe, especially for e-commerce businesses handling large volumes of EU citizen data. The remote, unauthenticated nature of the exploit increases the attack surface, making it easier for threat actors to target vulnerable systems across Europe. Organizations relying on this software without timely remediation may face increased risk of data breaches, financial loss, and operational disruption.

European organizations should immediately audit their use of the code-projects Online Shop Project version 1.0 and prioritize upgrading or patching the affected /login.php component. In the absence of an official patch, developers should implement input validation and sanitization on the Password parameter to prevent SQL injection. The use of parameterized queries or prepared statements is critical to eliminate injection vectors. Additionally, organizations should deploy web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting login endpoints. Regular security testing, including automated vulnerability scanning and manual code reviews, should be conducted to identify and remediate injection flaws. Monitoring logs for suspicious login attempts and anomalous database queries can help detect exploitation attempts early. Organizations should also ensure that database accounts used by the application have the least privileges necessary to limit the impact of any successful injection. Finally, educating developers on secure coding practices and maintaining an incident response plan for potential breaches will enhance overall resilience.
