CVE-2026-3760: University Management System SQLi Vulnerability

CVE-2026-3760 Overview

A SQL injection vulnerability has been identified in itsourcecode University Management System version 1.0. This vulnerability affects the file /view_result.php where manipulation of the seme parameter enables SQL injection attacks. The vulnerability can be exploited remotely without authentication, and a public exploit is available.

Critical Impact

Unauthenticated remote attackers can exploit the SQL injection vulnerability in the seme parameter to extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system.

Technical Details for CVE-2026-3760

Vulnerability Analysis

This SQL injection vulnerability resides in the /view_result.php endpoint of the University Management System. The application fails to properly sanitize user input passed through the seme parameter before incorporating it into SQL queries. This classic injection flaw allows attackers to manipulate database queries by injecting malicious SQL code through the vulnerable parameter.

The vulnerability is remotely exploitable without requiring authentication, making it particularly dangerous for internet-facing deployments. The impact includes potential unauthorized access to sensitive student records, grade information, and other educational data stored in the database.

Root Cause

The root cause of CVE-2026-3760 is improper input validation and lack of parameterized queries in the /view_result.php file. The seme parameter is directly concatenated into SQL statements without proper sanitization or the use of prepared statements, allowing attackers to inject arbitrary SQL commands.

Attack Vector

The attack can be carried out remotely over the network. An attacker can craft malicious HTTP requests to the /view_result.php endpoint with specially crafted values in the seme parameter. Since no authentication is required, any remote attacker with network access to the application can exploit this vulnerability.

The vulnerability allows for data extraction through techniques like UNION-based or blind SQL injection. Attackers may retrieve sensitive information including user credentials, student records, grades, and potentially administrative data stored in the database.

Detection Methods for CVE-2026-3760

Indicators of Compromise

• Unusual SQL error messages in application logs referencing /view_result.php
• HTTP requests to /view_result.php containing SQL syntax characters such as single quotes, UNION, SELECT, or comment sequences in the seme parameter
• Database query logs showing unexpected or malformed queries originating from the view_result functionality
• Evidence of data exfiltration or unauthorized database access patterns

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to /view_result.php
• Monitor HTTP access logs for requests containing SQL keywords or injection payloads in the seme parameter
• Implement database query logging and alert on anomalous query patterns or SQL errors
• Use intrusion detection systems (IDS) with SQL injection signature rules

Monitoring Recommendations

• Enable detailed logging for the University Management System application and database
• Set up alerts for multiple failed SQL query executions from the same source
• Monitor for unusual data access patterns or bulk data retrieval from student-related tables
• Review web server access logs regularly for suspicious parameter values targeting /view_result.php

How to Mitigate CVE-2026-3760

Immediate Actions Required

• Restrict network access to the University Management System to trusted IP ranges only
• Implement input validation and sanitization for the seme parameter immediately
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Consider taking the application offline if it processes sensitive data until a proper fix is implemented

Patch Information

No official vendor patch has been identified at this time. The application is distributed by itsourcecode and users should monitor the ITSourceCode website for security updates. Organizations using this software should implement the workarounds below and consider migrating to a more actively maintained solution.

Workarounds

• Implement parameterized queries or prepared statements in the /view_result.php file
• Apply strict input validation to reject SQL metacharacters in the seme parameter
• Use a Web Application Firewall to filter malicious SQL injection attempts
• Restrict database user permissions to limit the impact of successful exploitation
• Consider network segmentation to limit access to the application from untrusted networks
