CVE-2025-11558 identifies a SQL injection vulnerability in the code-projects E-Commerce Website version 1.0, located in the /pages/user_index_search.php file. The vulnerability stems from inadequate input validation or sanitization of the 'Search' parameter, which is directly incorporated into SQL queries. This flaw allows an unauthenticated remote attacker to manipulate the SQL query logic by injecting crafted input, potentially extracting sensitive data, modifying database contents, or causing denial of service through query disruption. The vulnerability does not require user interaction or privileges, making it accessible to any remote attacker with network access to the web application. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low complexity and no authentication required, but with limited impact on confidentiality, integrity, and availability (each rated low). Although no exploits have been observed in the wild, the public disclosure of exploit code increases the likelihood of exploitation attempts. The absence of official patches or vendor advisories necessitates immediate defensive measures by users of this platform. The vulnerability is critical for e-commerce environments where customer data and transaction integrity are paramount. Attackers could leverage this flaw to access customer information, manipulate orders, or disrupt service continuity, leading to reputational damage and regulatory consequences.

For European organizations, exploitation of CVE-2025-11558 could result in unauthorized access to sensitive customer data, including personal and payment information, violating GDPR requirements and potentially incurring heavy fines. Data integrity could be compromised by unauthorized modification of product listings, pricing, or order details, undermining business operations and customer trust. Availability impacts, while limited, could manifest as denial of service through database query manipulation, affecting e-commerce service uptime and revenue. The remote and unauthenticated nature of the vulnerability increases the attack surface, especially for publicly accessible e-commerce websites. Given the public availability of exploit code, attackers may rapidly target vulnerable installations, increasing the risk of data breaches and fraud. European organizations with significant online retail presence or handling large volumes of customer transactions are particularly at risk. The reputational damage and financial losses from such incidents could be substantial, especially in countries with strict data protection enforcement.

Organizations should immediately audit their use of the code-projects E-Commerce Website version 1.0 and identify any instances of the vulnerable /pages/user_index_search.php component. In the absence of an official patch, developers must implement robust input validation and sanitization for the 'Search' parameter, preferably using parameterized queries or prepared statements to prevent SQL injection. Web application firewalls (WAFs) should be configured to detect and block SQL injection patterns targeting this endpoint. Regular monitoring and analysis of web server and database logs can help identify suspicious query patterns indicative of exploitation attempts. Organizations should also consider isolating the affected application components within segmented network zones to limit potential lateral movement. Conducting penetration testing and code reviews focused on SQL injection vulnerabilities can uncover similar issues. Finally, organizations should maintain an incident response plan tailored to data breaches and web application attacks to respond swiftly if exploitation occurs.
