CVE-2024-0484: Fighting Cock Information System SQLi Flaw

CVE-2024-0484 Overview

A critical SQL Injection vulnerability has been identified in code-projects Fighting Cock Information System version 1.0. This issue affects the file admin/action/update_mother.php, where the manipulation of the age_mother parameter leads to SQL injection. The attack can be initiated remotely without authentication, and the exploit has been publicly disclosed.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to compromise the confidentiality, integrity, and availability of the database, potentially leading to unauthorized data access, data modification, or complete system compromise.

Technical Details for CVE-2024-0484

Vulnerability Analysis

This vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), commonly known as SQL Injection. The vulnerable endpoint admin/action/update_mother.php fails to properly sanitize or validate user-supplied input through the age_mother parameter before incorporating it into SQL queries. This allows attackers to inject malicious SQL statements that are executed by the database server with the same privileges as the application.

The exploitation of this vulnerability requires no authentication or user interaction. An attacker with network access to the application can directly manipulate the vulnerable parameter to extract sensitive database contents, modify or delete data, or potentially escalate to operating system command execution depending on the database configuration.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and sanitization in the update_mother.php file. The application directly incorporates user-supplied data from the age_mother parameter into SQL queries without using parameterized queries or prepared statements. This classic SQL injection pattern allows attackers to break out of the intended query structure and execute arbitrary SQL commands.

Attack Vector

The vulnerability is exploitable via the network attack vector through HTTP requests to the administrative endpoint. An attacker can craft malicious input for the age_mother parameter that includes SQL metacharacters and commands. The vulnerable PHP script processes this input and constructs a dynamic SQL query, allowing the injected SQL code to be executed against the backend database.

The attack does not require authentication, meaning any remote attacker with network access to the application can exploit this vulnerability. Successful exploitation could result in unauthorized access to the entire database, including user credentials, application data, and potentially system-level access depending on database permissions.

Detection Methods for CVE-2024-0484

Indicators of Compromise

• Unusual or malformed HTTP requests to admin/action/update_mother.php containing SQL syntax characters (e.g., single quotes, semicolons, UNION, SELECT keywords)
• Database error messages appearing in application logs or responses indicating SQL syntax errors
• Unexpected database queries or operations in database audit logs
• Evidence of data exfiltration or unauthorized database access in application logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to the vulnerable endpoint
• Monitor HTTP access logs for requests to update_mother.php with suspicious parameter values
• Enable database query logging and alert on queries containing unexpected SQL commands or patterns
• Deploy Intrusion Detection System (IDS) signatures for SQL injection attack patterns

Monitoring Recommendations

• Configure real-time alerting for SQL error messages in application and database logs
• Implement rate limiting on administrative endpoints to detect automated exploitation attempts
• Monitor for unusual database query patterns or execution times that may indicate data extraction
• Establish baseline metrics for database activity and alert on anomalies

How to Mitigate CVE-2024-0484

Immediate Actions Required

• Restrict network access to the administrative interface (/admin/) to trusted IP addresses only
• Implement input validation on the age_mother parameter to accept only numeric values
• Consider disabling the vulnerable endpoint until a proper fix can be applied
• Review database permissions and ensure the application uses a least-privilege database account

Patch Information

No official vendor patch has been identified for this vulnerability. Organizations using the Fighting Cock Information System should contact the vendor for remediation guidance or consider implementing the manual mitigations described below. For additional technical details, refer to the VulDB advisory or the Vicarius exploit analysis.

Workarounds

• Implement prepared statements with parameterized queries in the update_mother.php file to prevent SQL injection
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the application
• Apply input validation to ensure the age_mother parameter contains only expected numeric data
• Restrict access to administrative functions using network-level controls or additional authentication mechanisms

# Example: Apache .htaccess to restrict admin access
<Directory "/var/www/html/admin">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    # Replace with your trusted IP range
</Directory>
