CVE-2025-5367 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Online Shopping Portal Project, specifically within the /category.php file. The vulnerability arises from improper sanitization or validation of the 'Product' parameter, allowing an attacker to inject malicious SQL code. This injection can be performed remotely without requiring any authentication or user interaction, making exploitation straightforward. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been observed in the wild yet. The CVSS 4.0 score is 6.9 (medium severity), reflecting the ease of remote exploitation and potential for limited impact on confidentiality, integrity, and availability. The attack vector is network-based with low attack complexity and no privileges or user interaction needed. The vulnerability can lead to unauthorized data access, modification, or deletion within the backend database, potentially compromising sensitive customer and business data. However, the impact is considered limited (low) on confidentiality, integrity, and availability, possibly due to partial sanitization or database structure constraints. No official patches or mitigations have been published by the vendor at this time.

For European organizations using the PHPGurukul Online Shopping Portal Project 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 resulting in regulatory penalties. Data manipulation could disrupt business operations, damage reputation, and cause financial losses. Given the remote exploitation capability without authentication, attackers could automate attacks at scale, targeting multiple installations. The vulnerability could also serve as a foothold for further attacks within the network, such as privilege escalation or lateral movement. Although the CVSS score suggests medium severity, the actual impact depends on the deployment context, database sensitivity, and compensating controls in place. Organizations handling sensitive customer information or payment data are particularly at risk.

1. Immediate code review and remediation of the /category.php file to implement proper input validation and parameterized queries or prepared statements to prevent SQL injection. 2. Employ web application firewalls (WAFs) with SQL injection detection and blocking capabilities tailored to the specific attack patterns targeting the 'Product' parameter. 3. Conduct thorough penetration testing and code audits on the entire application to identify and remediate similar injection points. 4. Monitor application logs and network traffic for unusual query patterns or spikes in database errors indicative of exploitation attempts. 5. Apply strict database user permissions, limiting the application's database account to only necessary operations to minimize damage from potential injection. 6. If immediate patching is not possible, consider disabling or restricting access to the vulnerable functionality (/category.php) until a fix is deployed. 7. Educate developers on secure coding practices, especially regarding input sanitization and use of secure database access methods. 8. Maintain up-to-date backups of databases to enable recovery in case of data corruption or deletion.
