CVE-2025-11511 identifies a SQL injection vulnerability in the code-projects E-Commerce Website version 1.0, specifically within the /pages/supplier_add.php file. The vulnerability arises from improper sanitization of the supp_email parameter, which is susceptible to malicious input manipulation. An attacker can remotely exploit this flaw by injecting crafted SQL commands into the supp_email argument, potentially allowing unauthorized access to the database. This can lead to unauthorized data retrieval, modification, or deletion, impacting the confidentiality, integrity, and availability of the system's data. The vulnerability does not require authentication or user interaction, increasing its risk profile. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently active in the wild, the publication of the exploit code increases the likelihood of future attacks. The lack of available patches necessitates immediate mitigation through secure coding practices and input validation. This vulnerability is particularly concerning for organizations relying on this e-commerce platform for supplier management, as it could lead to exposure or manipulation of sensitive supplier data.

For European organizations using code-projects E-Commerce Website 1.0, this vulnerability poses a moderate risk of data breaches and operational disruption. Exploitation could allow attackers to extract sensitive supplier information, modify database records, or disrupt supplier onboarding processes, potentially affecting supply chain integrity. The remote exploitability without authentication increases the attack surface, especially for publicly accessible e-commerce portals. Compromise could lead to reputational damage, regulatory non-compliance (e.g., GDPR violations due to data exposure), and financial losses. The impact is amplified in countries with large e-commerce markets and extensive supplier networks, where such platforms are integral to business operations. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement. However, the medium severity and partial impact on confidentiality, integrity, and availability suggest that while serious, the threat is not critical but requires timely attention.

To mitigate CVE-2025-11511, organizations should immediately conduct a thorough code audit focusing on the /pages/supplier_add.php file and specifically the handling of the supp_email parameter. Implement strict input validation and sanitization to reject or neutralize malicious SQL syntax. Transition to using prepared statements or parameterized queries to prevent SQL injection. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this parameter. Monitor application logs for unusual database query patterns or repeated failed attempts to exploit the supp_email field. Restrict database user permissions to the minimum necessary to limit potential damage from injection attacks. Since no official patch is currently available, consider isolating or temporarily disabling the vulnerable functionality if feasible. Educate development teams on secure coding standards to prevent similar vulnerabilities. Finally, maintain an incident response plan to quickly address any exploitation attempts.
