CVE-2025-0297 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Book Shop application. The vulnerability exists in the /detail.php file, specifically in the handling of the 'id' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code into the backend database queries. This injection flaw allows unauthorized actors to interfere with the queries executed by the application, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability does not require user interaction and can be exploited remotely without authentication, increasing its risk profile. Although the exact database type and query structure are not disclosed, the ability to inject SQL commands typically enables attackers to extract sensitive customer information, manipulate order details, or escalate privileges within the application. The CVSS 4.0 score assigned is 5.3 (medium severity), reflecting the vulnerability's moderate impact and ease of exploitation with limited privileges required. No public exploit code is currently known to be in the wild, but the disclosure of the vulnerability increases the likelihood of future exploitation attempts. The lack of available patches or mitigation guidance from the vendor further elevates the risk for users of this software version.

For European organizations using the code-projects Online Book Shop version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of customer and transactional data. Exploitation could lead to unauthorized disclosure of personal data, violating GDPR requirements and potentially resulting in regulatory penalties and reputational damage. The integrity of order and inventory data could also be compromised, disrupting business operations and causing financial losses. Since the vulnerability can be exploited remotely without authentication, attackers could leverage it to gain deeper access into the organization's network or pivot to other systems. This is especially critical for small to medium-sized European retailers relying on this software for e-commerce, as they may lack robust security monitoring and incident response capabilities. Furthermore, the absence of patches means organizations must rely on alternative mitigations, increasing operational complexity and risk exposure.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, apply strict input validation and parameterized queries or prepared statements in the application code to prevent SQL injection. If modifying the source code is not feasible, deploy a Web Application Firewall (WAF) with custom rules to detect and block malicious SQL injection payloads targeting the 'id' parameter in /detail.php. Conduct thorough logging and monitoring of web requests to identify suspicious activity patterns. Restrict database user permissions to the minimum necessary, avoiding use of highly privileged accounts for application database connections. Network segmentation should isolate the web server from critical backend systems to limit lateral movement in case of compromise. Organizations should also consider temporarily disabling or restricting access to the vulnerable endpoint until a patch or secure update is available. Finally, maintain regular backups of databases and application data to enable recovery from potential data tampering or loss.
