CVE-2025-13580 identifies a SQL injection vulnerability in the code-projects Library System version 1.0, specifically within an unspecified function in the /mail.php file. The vulnerability arises from improper sanitization of the 'ID' parameter, which can be manipulated by remote attackers to inject malicious SQL code. This injection can lead to unauthorized data access, modification, or deletion within the underlying database. The attack vector is network-based (AV:N), requiring low attack complexity (AC:L) and no user interaction (UI:N). However, it requires low privileges (PR:L), indicating that some level of authenticated access or limited privileges might be necessary to exploit. The vulnerability impacts confidentiality, integrity, and availability at a low level (VC:L, VI:L, VA:L), and does not involve scope changes or security controls bypass. Although no known exploits are currently active in the wild, the public disclosure increases the likelihood of exploitation attempts. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts by affected organizations. The vulnerability's presence in a library management system could expose sensitive patron data or disrupt library services if exploited.

For European organizations, especially those operating public or academic libraries using the code-projects Library System 1.0, this vulnerability poses a risk of unauthorized data access or manipulation. Exploitation could lead to exposure of personally identifiable information (PII) of library users, unauthorized modification of library records, or denial of service through database corruption. This could result in reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions. The medium severity score suggests moderate risk, but the ease of remote exploitation without user interaction increases urgency. Organizations relying on this system for critical library functions or integrated with other institutional systems may face cascading impacts. The absence of known exploits in the wild currently limits immediate widespread impact but does not eliminate future risk.

1. Monitor vendor communications closely for official patches or updates and apply them promptly once released. 2. In the interim, implement strict input validation and sanitization on the 'ID' parameter in /mail.php to prevent injection attacks. 3. Employ parameterized queries or prepared statements in the application code to eliminate SQL injection vectors. 4. Restrict access to the affected system components to trusted networks and authenticated users with minimal privileges. 5. Enable detailed logging and monitoring to detect anomalous database queries or access patterns indicative of exploitation attempts. 6. Conduct security audits and code reviews focusing on input handling and database interactions within the Library System. 7. Consider deploying web application firewalls (WAFs) with rules targeting SQL injection patterns specific to this vulnerability. 8. Educate system administrators and developers about the risks and signs of SQL injection attacks to improve incident response readiness.
