CVE-2024-6196: Banking Management System SQLi Vulnerability

CVE-2024-6196 Overview

A critical SQL injection vulnerability has been identified in itsourcecode Banking Management System version 1.0. The vulnerability exists in the admin_class.php file, where improper handling of the username parameter allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion of sensitive banking information.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive financial data, or compromise the entire banking management database without requiring any authentication.

Affected Products

• itsourcecode Banking Management System Project in PHP version 1.0
• Systems running admin_class.php with vulnerable username parameter handling

Technical Details for CVE-2024-6196

Vulnerability Analysis

This SQL injection vulnerability occurs in the admin_class.php file of the Banking Management System. The application fails to properly sanitize user-supplied input in the username parameter before incorporating it into SQL queries. When a user submits login credentials or other data through the affected functionality, the application directly concatenates the username value into database queries without adequate input validation or parameterization.

The vulnerability can be exploited remotely without authentication, as the affected functionality appears to be accessible from the network. Successful exploitation could allow attackers to read, modify, or delete data from the underlying database, potentially compromising customer financial information, account credentials, and transaction records.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries (prepared statements) in the admin_class.php file. The application directly incorporates user-controlled input into SQL statements, creating an injection point that attackers can leverage to execute arbitrary SQL commands against the database backend.

Attack Vector

The attack is network-based and requires no authentication or user interaction, making it particularly dangerous. An attacker can craft malicious HTTP requests containing SQL injection payloads in the username parameter. When processed by the vulnerable admin_class.php file, these payloads are interpreted as part of the SQL query, allowing the attacker to:

• Bypass authentication mechanisms
• Extract sensitive database contents
• Modify or delete database records
• Potentially escalate to command execution depending on database configuration

Detection Methods for CVE-2024-6196

Indicators of Compromise

• Unusual SQL error messages appearing in application logs or HTTP responses
• Database queries containing SQL injection patterns such as ' OR '1'='1, UNION SELECT, or ; DROP TABLE
• Unexpected database access patterns or queries from the web application tier
• Authentication bypass events or login from unexpected IP addresses

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the username parameter
• Monitor application logs for SQL syntax errors or database exception messages that may indicate injection attempts
• Deploy database activity monitoring to detect anomalous queries or unauthorized data access
• Use intrusion detection systems (IDS) with SQL injection detection signatures

Monitoring Recommendations

• Enable detailed logging for the admin_class.php file and associated database queries
• Configure alerts for failed authentication attempts with unusual character patterns in usernames
• Monitor for large data extraction queries or unusual database response sizes
• Implement real-time alerting on database connection attempts from the web application with elevated privileges

How to Mitigate CVE-2024-6196

Immediate Actions Required

• Restrict network access to the Banking Management System to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Review and audit all database user permissions, applying the principle of least privilege
• Consider taking the affected system offline until a patch is available or code remediation is complete

Patch Information

As of the last update, no official vendor patch has been released for this vulnerability. Organizations using itsourcecode Banking Management System 1.0 should contact the vendor for remediation guidance or implement the workarounds described below. Monitor the VulDB entry for updates on patch availability.

Workarounds

• Modify admin_class.php to use prepared statements (parameterized queries) for all database operations involving user input
• Implement strict input validation to reject special characters commonly used in SQL injection attacks (single quotes, semicolons, SQL keywords)
• Deploy a WAF configured with SQL injection protection rules specifically for the login and authentication endpoints
• Restrict database user permissions to only the minimum required operations

# Example: Restrict access to admin_class.php via Apache .htaccess
<Files "admin_class.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    # Replace with your trusted network range
</Files>
