CVE-2025-9729 is a SQL Injection vulnerability identified in PHPGurukul Online Course Registration version 3.1, specifically within the /admin/student-registration.php file. The vulnerability arises from improper sanitization or validation of the 'studentname' parameter, allowing an attacker to manipulate this input to inject malicious SQL code. This flaw can be exploited remotely without requiring any authentication or user interaction, making it highly accessible to attackers. The injection can lead to unauthorized access to the backend database, potentially allowing attackers to read, modify, or delete sensitive data related to student registrations or other administrative information. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity, reflecting its ease of exploitation (network vector, no privileges required) but limited impact on confidentiality, integrity, and availability (low to limited impact). No patches or fixes have been publicly disclosed yet, and while no known exploits are currently active in the wild, the exploit code is publicly available, increasing the risk of exploitation.

For European organizations using PHPGurukul Online Course Registration 3.1, this vulnerability poses a significant risk to the confidentiality and integrity of student and administrative data. Educational institutions and training providers could face data breaches exposing personal information, which would violate GDPR regulations and lead to legal and reputational consequences. The ability to manipulate database queries remotely without authentication increases the risk of data tampering or unauthorized data extraction. Additionally, attackers could potentially escalate their access within the system or use the compromised platform as a pivot point for further attacks. The medium severity rating suggests that while the vulnerability is serious, the overall impact might be contained if the affected systems are properly segmented and monitored. However, given the critical nature of educational data and compliance requirements in Europe, the threat should be treated with urgency.

Organizations should immediately audit their use of PHPGurukul Online Course Registration version 3.1 and restrict access to the /admin/student-registration.php endpoint to trusted administrators only, ideally via VPN or IP whitelisting. Input validation and parameterized queries should be implemented to sanitize the 'studentname' parameter and prevent SQL injection. Until an official patch is released, deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this parameter can reduce risk. Regular database backups and monitoring for unusual query patterns or data access anomalies are recommended. Additionally, organizations should review and enforce strict access controls and logging on the affected systems to detect and respond to potential exploitation attempts promptly. Engaging with the vendor for timely patch releases and subscribing to vulnerability advisories is critical.
