CVE-2026-1701: Student Management System SQLi Vulnerability

CVE-2026-1701 Overview

A SQL injection vulnerability has been identified in itsourcecode Student Management System version 1.0. This security flaw affects the /enrollment/index.php file, where improper handling of the ID argument allows attackers to inject malicious SQL statements. The vulnerability is remotely exploitable without authentication, potentially enabling unauthorized access to sensitive student data, modification of database records, or complete compromise of the underlying database system.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive student information, modify enrollment records, or potentially gain broader access to the database server hosting the Student Management System.

Affected Products

• itsourcecode Student Management System 1.0
• /enrollment/index.php endpoint

Technical Details for CVE-2026-1701

Vulnerability Analysis

This SQL injection vulnerability exists due to insufficient input validation and sanitization of the ID parameter in the enrollment module. When user-supplied data is passed to the /enrollment/index.php endpoint, it is directly concatenated into SQL queries without proper escaping or parameterized query handling. This classic injection flaw allows attackers to manipulate the intended SQL logic, potentially bypassing authentication checks, exfiltrating data, or executing administrative database operations.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating that the application fails to properly sanitize special characters that have meaning in SQL syntax before incorporating user input into database queries.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and the use of unsanitized user input directly in SQL query construction. The ID parameter is not validated for type, length, or content before being incorporated into database queries. The application likely uses string concatenation to build SQL statements rather than implementing prepared statements with parameterized queries, which would prevent injection attacks by treating user input as data rather than executable code.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the /enrollment/index.php endpoint with specially crafted ID parameter values containing SQL injection payloads. These payloads can include UNION-based injection to extract data from other tables, boolean-based blind injection to enumerate database contents, or time-based blind injection when direct output is not available.

The vulnerability is exploitable by manipulating the ID parameter with SQL metacharacters and injection payloads. For example, appending SQL operators and statements to the expected numeric ID value can alter query logic. Attackers typically begin by testing for injection points using single quotes or boolean conditions, then escalate to data extraction using UNION SELECT statements or database-specific functions. For detailed technical analysis, refer to the GitHub Issue CVE Discussion and VulDB CVE Advisory #343491.

Detection Methods for CVE-2026-1701

Indicators of Compromise

• Unusual or malformed requests to /enrollment/index.php containing SQL metacharacters such as single quotes, double dashes, or UNION keywords in the ID parameter
• Database error messages appearing in HTTP responses indicating SQL syntax errors
• Unexpected database queries accessing multiple tables or attempting to extract schema information
• Anomalous patterns of requests to the enrollment endpoint from single source IPs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the ID parameter
• Implement application-level logging for all requests to /enrollment/index.php with parameter inspection
• Configure database query monitoring to alert on unusual query patterns including UNION SELECT, information_schema access, or sleep/benchmark functions
• Enable HTTP request logging and analyze for SQL injection signatures using SIEM correlation rules

Monitoring Recommendations

• Establish baseline traffic patterns to the enrollment module and alert on statistical anomalies
• Monitor database server logs for authentication failures, unusual query patterns, or elevated privilege usage
• Implement real-time alerting for web application errors that may indicate injection attempts
• Review access logs periodically for reconnaissance patterns targeting PHP endpoints

How to Mitigate CVE-2026-1701

Immediate Actions Required

• Restrict access to the /enrollment/index.php endpoint using network segmentation or authentication requirements until a patch is applied
• Implement input validation on the ID parameter to ensure only numeric values are accepted
• Deploy WAF rules specifically targeting SQL injection attempts on the affected endpoint
• Review database account permissions to implement least privilege access for the web application

Patch Information

As of the last update (2026-02-04), no official patch has been released by the vendor. Organizations using itsourcecode Student Management System should monitor the ITSourceCode Security Resources for security updates and patch availability. In the interim, implementing the workarounds and mitigation strategies below is strongly recommended.

Workarounds

• Implement server-side input validation to reject any non-numeric characters in the ID parameter before processing
• Modify the application code to use prepared statements with parameterized queries instead of string concatenation for all database operations
• Deploy a reverse proxy or WAF with SQL injection detection capabilities in front of the application
• Consider taking the affected enrollment module offline if it is not critical to operations until proper remediation is complete

# Example Apache mod_rewrite rule to block SQL injection attempts
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} [^\w](union|select|insert|update|delete|drop|--|;|'|") [NC]
RewriteRule ^enrollment/index\.php$ - [F,L]
