CVE-2025-4313 is a SQL Injection vulnerability identified in SourceCodester Advanced Web Store version 1.0, specifically within the /admin/admin_addnew_product.php file. The vulnerability arises from improper sanitization or validation of the txtProdId parameter, which can be manipulated by an attacker to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability is classified as critical due to its potential to compromise the confidentiality, integrity, and availability of the database and the web application. Exploiting this vulnerability could enable attackers to extract sensitive data, modify or delete records, and potentially escalate privileges or pivot to other parts of the network. Although no public exploits are currently known to be in the wild, the disclosure of the vulnerability increases the risk of exploitation. The CVSS 4.0 base score is 6.9, indicating a medium severity level, reflecting the ease of exploitation (network vector, no privileges or user interaction required) but limited scope and impact on the system components. The vulnerability affects only version 1.0 of the product, which is an e-commerce web store platform used to manage product listings and sales. The lack of available patches or mitigations from the vendor at this time increases the urgency for organizations to implement compensating controls.

For European organizations using SourceCodester Advanced Web Store 1.0, this vulnerability poses a significant risk to their e-commerce operations. Successful exploitation could lead to unauthorized access to customer data, including personally identifiable information (PII), payment details, and order histories, which would violate GDPR requirements and potentially result in regulatory fines and reputational damage. Additionally, attackers could manipulate product listings or pricing, disrupt sales processes, or deface the online store, impacting business continuity and customer trust. The remote and unauthenticated nature of the attack vector means that attackers can exploit this vulnerability from anywhere, increasing the threat surface. Given the critical role of e-commerce platforms in retail and supply chain operations, this vulnerability could also have cascading effects on inventory management and financial reporting. Organizations in sectors with high online transaction volumes, such as retail, wholesale, and manufacturing, are particularly at risk. The medium CVSS score suggests that while the vulnerability is serious, the impact may be somewhat contained by the limited market penetration of the affected product and the absence of known active exploits.

To mitigate this vulnerability, European organizations should immediately audit their use of SourceCodester Advanced Web Store 1.0 and identify any instances of the affected software. Since no official patches are currently available, organizations should implement the following specific measures: 1) Apply input validation and parameterized queries or prepared statements in the /admin/admin_addnew_product.php script to prevent SQL injection, if source code access is available. 2) Restrict access to the /admin/ directory using network-level controls such as IP whitelisting, VPN access, or web application firewalls (WAFs) configured to detect and block SQL injection patterns targeting the txtProdId parameter. 3) Monitor web server and database logs for unusual queries or access patterns indicative of exploitation attempts. 4) Conduct regular security assessments and penetration testing focused on injection vulnerabilities. 5) Consider isolating the affected application within segmented network zones to limit lateral movement in case of compromise. 6) Engage with the vendor or community for updates or patches and plan for an upgrade to a secure version once available. 7) Educate administrators on secure coding practices and the risks associated with SQL injection to prevent similar issues in customizations or future deployments.
