CVE-2025-14336 identifies a SQL injection vulnerability in the itsourcecode Student Management System version 1.0, affecting the /promote.php endpoint through the 'sy' parameter. This vulnerability allows an attacker to remotely inject crafted SQL statements without requiring authentication or user interaction, exploiting insufficient input validation or improper sanitization of the 'sy' parameter. The injection can lead to unauthorized access to the database, enabling attackers to read, modify, or delete sensitive student records or administrative data. The CVSS 4.0 score of 6.9 (medium severity) reflects the network attack vector, low complexity, no privileges or user interaction needed, but limited impact on confidentiality, integrity, and availability. Although no active exploits have been reported in the wild, the public disclosure of the exploit code increases the risk of exploitation. The vulnerability stems from poor coding practices in handling user-supplied input in a critical student management function, potentially allowing attackers to escalate their impact by manipulating student promotion data. The lack of vendor patches or official remediation guidance necessitates immediate defensive measures by administrators. Given the critical nature of educational data and the widespread use of student management systems, this vulnerability poses a tangible threat to data security and operational continuity.

For European organizations, particularly educational institutions using the itsourcecode Student Management System 1.0, this vulnerability could lead to unauthorized disclosure of sensitive student and staff information, including personal identification and academic records. The integrity of student promotion data could be compromised, leading to inaccurate academic results or administrative errors. Availability of the system may also be affected if attackers execute destructive SQL commands or cause database corruption. Such incidents could result in regulatory non-compliance with GDPR due to data breaches, reputational damage, and potential financial penalties. The remote and unauthenticated nature of the exploit increases the attack surface, making even less technically sophisticated attackers capable of exploiting the flaw. The public availability of exploit code further elevates the risk of opportunistic attacks targeting vulnerable installations. Disruption of educational services could impact teaching and administrative operations, especially during critical academic periods.

Since no official patches are currently available, organizations should immediately implement input validation and sanitization on the 'sy' parameter in /promote.php to block malicious SQL payloads. Employ parameterized queries or prepared statements to prevent injection attacks. Restrict network access to the Student Management System to trusted IP ranges and deploy web application firewalls (WAFs) with SQL injection detection rules to detect and block exploit attempts. Conduct thorough code reviews and security testing of the application to identify and remediate similar vulnerabilities. Monitor logs for suspicious database queries or unusual application behavior. Educate administrators on the risk and ensure backups of critical data are maintained to enable recovery in case of compromise. Engage with the vendor or community to obtain or develop official patches. Consider isolating the affected system within a segmented network zone to limit potential lateral movement.
