CVE-2025-13242 is a SQL injection vulnerability identified in the code-projects Student Information System version 2.0, specifically within the /register.php endpoint. The vulnerability arises from improper handling of user-supplied input that is directly incorporated into SQL queries without adequate sanitization or parameterization. This flaw allows a remote attacker to inject malicious SQL code, potentially enabling unauthorized access to or modification of the underlying database. The attack vector requires no 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:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently active in the wild, the public disclosure of the vulnerability means that threat actors could develop exploits. The Student Information System is commonly deployed in educational institutions to manage sensitive student data, including personal and academic records. Exploitation could lead to data leakage, unauthorized data manipulation, or denial of service conditions. The lack of available patches necessitates immediate mitigation efforts by affected organizations. The vulnerability underscores the importance of secure coding practices such as input validation and the use of prepared statements to prevent SQL injection attacks.

For European organizations, particularly educational institutions using the code-projects Student Information System 2.0, this vulnerability poses a risk of unauthorized access to sensitive student data, including personal identification and academic records. Successful exploitation could lead to data breaches, data tampering, or service disruption, undermining trust and potentially violating data protection regulations such as GDPR. The exposure of confidential student information could result in reputational damage and legal consequences. Additionally, attackers could leverage the vulnerability to pivot within the network, escalating their access or causing further damage. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially in environments where the system is accessible from the internet or poorly segmented networks. The medium severity rating suggests a moderate but significant threat that requires timely attention to avoid operational and compliance risks.

1. Immediate implementation of input validation and sanitization on all user inputs, especially those processed by /register.php, to block malicious SQL code. 2. Refactor the application code to use parameterized queries or prepared statements to eliminate direct concatenation of user inputs into SQL commands. 3. Restrict network access to the Student Information System, limiting exposure to trusted internal networks or VPNs. 4. Employ web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting the affected endpoint. 5. Conduct thorough code reviews and security testing to identify and remediate similar injection flaws in other parts of the application. 6. Monitor logs for suspicious database query patterns or repeated failed attempts indicative of exploitation attempts. 7. Engage with the vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 8. Educate development and IT teams on secure coding practices and the importance of timely vulnerability management. 9. Consider isolating the Student Information System in a segmented network zone to limit potential lateral movement in case of compromise.
