CVE-2024-9091 Overview
A SQL injection vulnerability has been identified in code-projects Student Record System version 1.0. This vulnerability exists in the /index.php file, where improper handling of the regno parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially allowing attackers to read, modify, or delete sensitive data from the application's database.
Critical Impact
Unauthenticated remote attackers can exploit this SQL injection vulnerability to access sensitive student records, manipulate database contents, or potentially gain unauthorized access to the underlying system.

Technical Details for CVE-2024-9091
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) affects the /index.php endpoint in the code-projects Student Record System. The application fails to properly sanitize user-supplied input in the regno parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL commands that are then executed by the database server.
The vulnerability is network-accessible, meaning any remote attacker can target the vulnerable endpoint without requiring authentication or user interaction. Successful exploitation could result in unauthorized access to student records, administrative credentials, or other sensitive information stored in the database.
Root Cause
The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements when processing the regno parameter. The application directly concatenates user input into SQL queries without sanitization, creating an injection point that attackers can exploit.
Attack Vector
The attack can be launched remotely by submitting malicious SQL syntax through the regno parameter in requests to the /index.php file. An attacker can craft specially formed input containing SQL metacharacters and commands to manipulate the intended query logic.
For example, an attacker could inject SQL code through the regno parameter to bypass authentication checks, extract database contents using UNION-based techniques, or perform time-based blind SQL injection to enumerate the database structure. The exploit has been publicly disclosed, as referenced in the GitHub Issue Discussion.
Detection Methods for CVE-2024-9091
Indicators of Compromise
- Unusual or malformed requests to /index.php containing SQL syntax such as UNION SELECT, OR 1=1, single quotes, or comment sequences (--, /**/)
- Database error messages in application logs indicating SQL syntax errors from user input
- Unexpected database query patterns or elevated query execution times suggesting injection attempts
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the regno parameter
- Enable detailed logging for requests to /index.php and monitor for suspicious input patterns
- Implement database activity monitoring to detect anomalous queries or data extraction attempts
Monitoring Recommendations
- Review web server access logs for requests containing SQL injection signatures targeting the regno parameter
- Monitor database audit logs for unauthorized SELECT, INSERT, UPDATE, or DELETE operations
- Set up alerts for multiple failed authentication attempts or unusual data access patterns
How to Mitigate CVE-2024-9091
Immediate Actions Required
- Restrict access to the vulnerable /index.php endpoint until a patch is applied
- Deploy WAF rules to filter malicious input in the regno parameter
- Consider disabling the affected functionality if it is not business-critical
- Review database permissions to ensure the application uses least-privilege access
Patch Information
No official patch has been released by the vendor at this time. Organizations using code-projects Student Record System 1.0 should monitor the Code Projects Resource Hub for security updates. Additional vulnerability details are available at VulDB ID #278269.
Workarounds
- Implement input validation on the regno parameter to allow only alphanumeric characters
- Use prepared statements or parameterized queries to prevent SQL injection in the application code
- Deploy a reverse proxy or WAF to filter and sanitize incoming requests before they reach the application
- Restrict network access to the application to trusted IP ranges only
# Example: Basic Apache ModSecurity rule to block SQL injection attempts
SecRule ARGS:regno "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Blocked'"
