CVE-2025-13242 Overview
A SQL injection vulnerability has been identified in code-projects Student Information System 2.0. This security flaw affects the processing of the /register.php file, where improper input handling allows attackers to manipulate SQL queries. The vulnerability can be exploited remotely without authentication, and exploit details have been publicly disclosed.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive student information in the database, potentially compromising the confidentiality and integrity of educational records.

Technical Details for CVE-2025-13242
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) exists within the /register.php endpoint of the Student Information System application. The vulnerability falls under the broader category of injection flaws (CWE-74), where user-supplied input is not properly sanitized before being incorporated into SQL queries executed against the backend database.
The attack can be carried out remotely over the network without requiring any prior authentication or user interaction. Successful exploitation could allow an attacker to read sensitive data from the database, modify or delete records, and potentially execute administrative operations on the database server.
Root Cause
The root cause of this vulnerability is improper input validation and insufficient sanitization of user-controllable parameters within the /register.php file. The application fails to properly escape or parameterize user input before constructing SQL queries, allowing malicious SQL statements to be injected and executed by the database engine.
Attack Vector
The attack is network-based, targeting the /register.php endpoint of the Student Information System web application. An unauthenticated remote attacker can craft malicious HTTP requests containing SQL injection payloads in form parameters processed by this file. When these payloads are processed by the vulnerable application, the injected SQL commands are executed against the database.
The vulnerability mechanism involves manipulation of input parameters that are directly concatenated into SQL query strings without proper sanitization. For technical details on the specific injection points, refer to the GitHub CVE Documentation.
Detection Methods for CVE-2025-13242
Indicators of Compromise
- Unusual or malformed HTTP requests to /register.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
- Database error messages in application logs indicating syntax errors or unexpected query behavior
- Unexpected database queries or administrative commands in database audit logs
- Anomalous data access patterns or bulk data retrieval from student records tables
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /register.php endpoint
- Implement database activity monitoring to identify suspicious query patterns or unauthorized data access
- Configure application logging to capture detailed request parameters for the affected registration endpoint
- Use intrusion detection systems with SQL injection signature rules
Monitoring Recommendations
- Enable verbose logging on the web server to capture all requests to /register.php
- Monitor database query logs for anomalous patterns including UNION-based attacks, time-based blind injection attempts, or error-based extraction
- Set up alerts for failed login attempts or registration anomalies that may indicate exploitation attempts
How to Mitigate CVE-2025-13242
Immediate Actions Required
- Restrict access to the /register.php endpoint through network-level controls or authentication requirements
- Implement input validation and sanitization for all user-controllable parameters
- Deploy a Web Application Firewall with SQL injection protection rules
- Review and audit the application codebase for similar injection vulnerabilities
Patch Information
No official vendor patch has been released at this time. Organizations using the affected Student Information System 2.0 should contact the vendor or apply code-level mitigations. For additional information, refer to the VulDB entry #332568 and the Code Projects Resource Hub.
Workarounds
- Implement prepared statements and parameterized queries throughout the application to prevent SQL injection
- Use input validation to whitelist acceptable characters and reject malicious payloads
- Deploy a reverse proxy or WAF to filter malicious requests before they reach the application
- Consider disabling or restricting access to the registration functionality until a proper fix is applied
# Example: Apache mod_security rule to block SQL injection attempts
SecRule REQUEST_URI "@contains /register.php" \
"id:1001,phase:2,deny,status:403,\
chain"
SecRule ARGS "@detectSQLi" \
"t:none,t:urlDecodeUni,t:htmlEntityDecode"
