CVE-2025-11511 identifies a SQL injection vulnerability in the code-projects E-Commerce Website version 1.0, located in the /pages/supplier_add.php file. The vulnerability stems from insufficient input validation of the supp_email parameter, which is used in SQL queries without proper sanitization or parameterization. This allows a remote attacker to inject malicious SQL code, potentially manipulating the backend database. The attack vector is network accessible (AV:N), requires low attack complexity (AC:L), and does not require authentication (PR:L) or user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability at a low level (VC:L, VI:L, VA:L), indicating partial but not full compromise potential. The scope is unchanged (S:N), meaning the vulnerability affects only the vulnerable component. The exploitability is partially functional (E:P). Although no exploits are currently known in the wild, the public disclosure of the vulnerability increases the risk of future exploitation. The lack of official patches or mitigation guidance from the vendor necessitates immediate defensive actions by users. This vulnerability could allow attackers to extract sensitive supplier information, modify database records, or disrupt e-commerce operations by injecting malicious SQL commands. Given the critical role of e-commerce platforms in business operations, this vulnerability poses a tangible risk to data security and service continuity.

For European organizations using the affected code-projects E-Commerce Website 1.0, this vulnerability could lead to unauthorized access to sensitive supplier data, including emails and potentially other linked information. Attackers exploiting this flaw could alter database contents, leading to data integrity issues or service disruptions. The compromise of supplier data could have cascading effects on supply chain security and business relationships. Additionally, the injection could be leveraged to execute further attacks such as privilege escalation or data exfiltration. Given the remote exploitability without authentication, attackers can target vulnerable systems over the internet, increasing exposure. The impact on availability is limited but possible if attackers manipulate database queries to cause errors or downtime. European e-commerce businesses relying on this platform may face reputational damage, regulatory penalties under GDPR for data breaches, and financial losses. The medium severity rating suggests that while the threat is significant, it is not critical, but timely remediation is essential to prevent escalation.

Since no official patches are currently available, European organizations should immediately implement the following mitigations: 1) Conduct a thorough code review of the /pages/supplier_add.php file and any other input handling code to identify and remediate unsafe SQL query constructions. 2) Apply input validation and sanitization on the supp_email parameter, ensuring it conforms to expected email formats and rejects malicious payloads. 3) Refactor database queries to use parameterized prepared statements or stored procedures to prevent SQL injection. 4) Implement Web Application Firewalls (WAFs) with rules to detect and block SQL injection patterns targeting the supp_email parameter. 5) Monitor database logs and web server logs for unusual query patterns or error messages indicative of injection attempts. 6) Restrict database user privileges to the minimum necessary to limit the impact of a successful injection. 7) If feasible, isolate the vulnerable application in a segmented network zone to reduce exposure. 8) Engage with the vendor or community to track patch releases and apply updates promptly once available. 9) Educate development and security teams about secure coding practices to prevent similar vulnerabilities. 10) Consider deploying runtime application self-protection (RASP) solutions to detect and block injection attacks in real-time.
