CVE-2025-15075: Student Management System SQLi Vulnerability

CVE-2025-15075 Overview

A SQL injection vulnerability has been discovered in itsourcecode Student Management System version 1.0. This security flaw affects the processing of the /student_p.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL statements. The vulnerability can be exploited remotely without authentication, and a public exploit has been disclosed.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete sensitive student data from the database without requiring any authentication credentials.

Technical Details for CVE-2025-15075

Vulnerability Analysis

This SQL injection vulnerability exists in the /student_p.php endpoint of the Student Management System. The application fails to properly sanitize user-supplied input passed through the ID parameter before incorporating it into SQL queries. This allows an attacker to craft malicious input that modifies the intended SQL logic, potentially gaining unauthorized access to the underlying database.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where untrusted data is sent to an interpreter as part of a command or query. In this case, the lack of parameterized queries or proper input validation enables direct manipulation of database operations.

Root Cause

The root cause of this vulnerability stems from inadequate input validation and the use of unsanitized user input in SQL query construction. The /student_p.php file directly incorporates the ID parameter value into database queries without employing prepared statements or proper escaping mechanisms. This fundamental secure coding oversight allows malicious SQL syntax to be interpreted by the database engine.

Attack Vector

The attack can be initiated remotely over the network by any unauthenticated user. An attacker can manipulate the ID parameter in HTTP requests to the /student_p.php endpoint to inject arbitrary SQL commands. This could allow the attacker to:

Extract sensitive student records and personal information
Modify or delete database contents
Potentially escalate access depending on database permissions
Enumerate database structure and other tables

The vulnerability requires no user interaction and can be exploited with low complexity, making it accessible to attackers with basic SQL injection knowledge.

Detection Methods for CVE-2025-15075

Indicators of Compromise

Unusual or malformed requests to /student_p.php containing SQL syntax characters such as single quotes, double dashes, or UNION statements
Database error messages appearing in application logs or responses
Unexpected database queries or access patterns in database audit logs
Anomalous data extraction or bulk read operations from student-related tables

Detection Strategies

Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the ID parameter
Monitor HTTP request logs for suspicious payloads containing SQL keywords like SELECT, UNION, DROP, or comment sequences
Implement database activity monitoring to detect anomalous query patterns
Configure application logging to capture and alert on database errors that may indicate injection attempts

Monitoring Recommendations

Enable detailed logging for all requests to /student_p.php and similar PHP endpoints
Set up alerts for multiple failed database queries or SQL syntax errors from the same source IP
Monitor for data exfiltration patterns such as unusually large response sizes from the vulnerable endpoint
Review database logs for unauthorized access attempts or privilege escalation queries

How to Mitigate CVE-2025-15075

Immediate Actions Required

Restrict access to the /student_p.php endpoint until a patch is available or the code is remediated
Implement input validation on the ID parameter to accept only expected numeric values
Deploy WAF rules to block common SQL injection patterns targeting this endpoint
Review database user permissions to ensure the application uses least-privilege access

Patch Information

No official vendor patch has been released at this time. Organizations using the Student Management System should monitor the vendor's website and the GitHub CVE Issue Discussion for updates. Additional technical details are available in VulDB Entry #338332.

Workarounds

Implement prepared statements or parameterized queries in the /student_p.php file to prevent SQL injection
Add server-side input validation to ensure the ID parameter contains only valid integer values
Restrict network access to the application using firewall rules or VPN requirements
Consider taking the application offline or disabling the vulnerable functionality until proper remediation can be implemented

bash

# Example: Restrict access to vulnerable endpoint using .htaccess
<Files "student_p.php">
    Order Deny,Allow
    Deny from all
    # Allow only trusted IP ranges
    Allow from 192.168.1.0/24
</Files>
