DescriptionCVE.org

A vulnerability was determined in SourceCodester Student Result Management System 1.0. The impacted element is an unknown function of the file /admin/core/import_users.php of the component Bulk Import. This manipulation of the argument File causes improper access controls. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized.

Executive ViewAI

Why It Matters

A high-severity vulnerability in the Student Result Management System's bulk user import feature could allow unauthorized users to manipulate student records and administrative data. This poses immediate risk to data integrity, student privacy, and institutional compliance if the affected system is internet-facing or accessible to untrusted users.

Business Impact: High

Compensating Controls

Restrict access to /admin/core/import_users.php via firewall or WAF rules (IP allowlisting, require VPN); disable the bulk import feature if not mission-critical; implement multi-factor authentication for admin accounts; enable comprehensive audit logging for all import operations and database modifications; segment the application network from student-facing systems; conduct manual review of all imported records before activation.
