CVE-2025-4314 is a SQL Injection vulnerability identified in SourceCodester Advanced Web Store version 1.0, specifically within the /admin/index.php file. The vulnerability arises from improper sanitization of the txtLogin parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring authentication or user interaction, injecting crafted SQL commands that the backend database executes. This can lead to unauthorized data access, data modification, or even complete compromise of the underlying database. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known active exploits have been reported in the wild yet. The CVSS 4.0 score is 6.9, indicating a medium severity level, reflecting the ease of exploitation (no privileges or user interaction needed) but limited scope of impact (confidentiality, integrity, and availability impacts are low to limited). The vulnerability affects only version 1.0 of the Advanced Web Store product by SourceCodester, which is a web-based e-commerce platform. Since the vulnerability is in the admin login functionality, successful exploitation could allow attackers to bypass authentication or manipulate administrative data, potentially leading to further compromise of the web store environment.

For European organizations using SourceCodester Advanced Web Store 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their e-commerce data, including customer information, order details, and payment data. Exploitation could lead to unauthorized access to sensitive administrative functions, data leakage, or manipulation of transactional data, undermining customer trust and potentially causing financial losses. Additionally, compromised web stores could be used as a foothold for further attacks within the organization's network. Given the remote and unauthenticated nature of the exploit, attackers can target vulnerable installations at scale, increasing the risk of widespread impact. Organizations in Europe that rely on this software for online sales may face regulatory scrutiny under GDPR if personal data is exposed. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system takeover without additional vulnerabilities or misconfigurations.

To mitigate this vulnerability, European organizations should immediately identify any deployments of SourceCodester Advanced Web Store version 1.0. Since no official patches are currently linked, organizations should implement the following specific measures: 1) Apply input validation and parameterized queries or prepared statements in the /admin/index.php file to sanitize the txtLogin parameter and prevent SQL injection. 2) Restrict access to the admin interface by IP whitelisting or VPN-only access to reduce exposure. 3) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the txtLogin parameter. 4) Monitor logs for suspicious activity related to admin login attempts and unusual database queries. 5) Consider upgrading or migrating to a more secure and actively maintained e-commerce platform if possible. 6) Conduct regular security assessments and penetration testing focused on injection flaws. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and access controls relevant to this product and vulnerability.
