CVE-2025-4312 is a SQL Injection vulnerability identified in SourceCodester Advanced Web Store version 1.0, specifically affecting the /productdetail.php file. The vulnerability arises from improper sanitization or validation of the 'prodid' parameter, which is used in SQL queries. An attacker can manipulate this parameter remotely without any authentication or user interaction to inject malicious SQL code. This can lead to unauthorized access to the backend database, allowing attackers to read, modify, or delete sensitive data, potentially compromising the confidentiality, integrity, and availability of the web store's data. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The CVSS 4.0 base score is 6.9, indicating a medium severity level, primarily due to the lack of authentication required and ease of exploitation, but with limited impact on confidentiality, integrity, and availability (each rated low). The vulnerability does not require user interaction and can be exploited remotely over the network, making it a significant risk for affected deployments.

For European organizations using SourceCodester Advanced Web Store 1.0, this vulnerability poses a tangible risk of data breaches, unauthorized data manipulation, and potential disruption of e-commerce operations. Compromise of customer data, including personal and payment information, could lead to regulatory penalties under GDPR and damage to brand reputation. The ability to alter product details or inventory could disrupt business processes and customer trust. Since the vulnerability allows remote exploitation without authentication, attackers can target vulnerable web stores en masse, increasing the likelihood of widespread impact. Additionally, exploitation could serve as a foothold for further attacks within the organization's network. The medium severity rating suggests that while the impact is significant, it may not lead to full system compromise or widespread service outages without additional vulnerabilities.

European organizations should immediately assess their use of SourceCodester Advanced Web Store 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, organizations should implement strict input validation and parameterized queries or prepared statements for the 'prodid' parameter to prevent SQL injection. Web Application Firewalls (WAFs) should be configured to detect and block SQL injection attempts targeting the vulnerable endpoint. Regular security audits and code reviews focusing on input handling should be conducted. Additionally, organizations should monitor web server logs for suspicious activity related to the 'prodid' parameter and implement network segmentation to limit potential lateral movement if exploitation occurs. Backup and incident response plans should be updated to quickly recover from potential data integrity issues.
