CVE-2025-11343 identifies a SQL injection vulnerability in the Student Crud Operation 3.3 application developed by code-projects. The flaw exists in the delete.php script, where the 'ID' parameter is not properly sanitized or validated before being used in SQL queries. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially manipulating the backend database. The vulnerability does not require user interaction or privileges, making it easier to exploit remotely over the network. The CVSS 4.0 base score is 6.9 (medium), reflecting the moderate impact on confidentiality, integrity, and availability, with low complexity and no authentication required. Exploiting this vulnerability could enable attackers to read, modify, or delete sensitive student records or other data stored in the database, leading to data breaches or service disruptions. Although no public exploit code is currently known to be actively used, the public disclosure increases the likelihood of future exploitation attempts. The vulnerability affects only version 3.3 of the product, and no official patches have been linked yet, emphasizing the need for immediate mitigation. This vulnerability is particularly relevant for educational institutions or organizations managing student data using this software or similar CRUD applications.

For European organizations, especially educational institutions and administrative bodies using the Student Crud Operation 3.3 application, this vulnerability poses a significant risk to the confidentiality and integrity of student and administrative data. Successful exploitation could lead to unauthorized disclosure of personal data, violating GDPR and other data protection regulations, resulting in legal and financial penalties. Data manipulation or deletion could disrupt critical academic and administrative processes, impacting availability and operational continuity. The remote, unauthenticated nature of the attack vector increases the threat surface, potentially allowing attackers to compromise systems without insider access. This risk is heightened in countries with widespread adoption of this software or similar platforms, where sensitive student information is processed and stored. Additionally, reputational damage from data breaches could affect trust in affected institutions. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise but still requires urgent attention to prevent exploitation.

European organizations should immediately implement the following specific mitigations: 1) Apply input validation and sanitization on all user-supplied parameters, especially the 'ID' parameter in delete.php, to prevent SQL injection. 2) Refactor database queries to use parameterized statements or prepared queries rather than dynamic SQL concatenation. 3) Restrict database user permissions to the minimum necessary to limit the impact of potential injection attacks. 4) Monitor database and application logs for unusual query patterns or repeated failed attempts targeting the 'ID' parameter. 5) If official patches become available, prioritize their deployment in all affected environments. 6) Conduct a thorough code review of similar CRUD operations within the application to identify and remediate other injection points. 7) Implement Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting this endpoint. 8) Educate developers and administrators on secure coding practices and the importance of input validation. 9) Regularly back up databases and verify backup integrity to enable recovery in case of data tampering or deletion. 10) Consider isolating or segmenting the affected application environment to reduce lateral movement risk if exploited.
