CVE-2025-4031 is a critical SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Pre-School Enrollment System, specifically within the /admin/aboutus.php file. The vulnerability arises from improper sanitization or validation of the 'pagetitle' parameter, which is directly manipulated by an attacker to inject malicious SQL commands. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL queries against the backend database. The injection can lead to unauthorized data access, data modification, or even complete compromise of the database server. The vulnerability does not require any user interaction or privileges, making exploitation straightforward. Although no public exploits have been observed in the wild yet, the vulnerability details have been publicly disclosed, increasing the risk of exploitation attempts. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. However, the potential for data leakage or manipulation in an enrollment system that likely stores sensitive personal information about children and their families elevates the risk profile. The lack of available patches or vendor advisories at this time further complicates mitigation efforts.

For European organizations, particularly educational institutions and local government bodies managing pre-school enrollment systems, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of personally identifiable information (PII) of children and their guardians, violating GDPR and other data protection regulations, potentially resulting in legal penalties and reputational damage. Integrity of enrollment data could be compromised, leading to administrative disruption and loss of trust. Availability impacts are less pronounced but could occur if attackers execute destructive SQL commands. Given the critical nature of educational data and the sensitivity of the affected demographic, the impact extends beyond technical damage to societal and regulatory consequences. Organizations using PHPGurukul Pre-School Enrollment System 1.0 should consider this vulnerability a priority for remediation or mitigation.

1. Immediate mitigation should include implementing web application firewall (WAF) rules to detect and block SQL injection attempts targeting the 'pagetitle' parameter, focusing on suspicious input patterns and SQL keywords. 2. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements for all database interactions, especially in the /admin/aboutus.php file. 3. If possible, isolate the enrollment system in a segmented network zone with strict access controls to limit exposure. 4. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5. Engage with the vendor or community to obtain or develop patches; if unavailable, consider migrating to alternative enrollment solutions with secure coding practices. 6. Educate administrative users about the risk and enforce strong authentication and access policies to reduce the attack surface. 7. Regularly back up enrollment data securely to enable recovery in case of data tampering or loss.
