CVE-2024-10431: Pet Shop Management System SQL Injection

CVE-2024-10431 Overview

A critical SQL injection vulnerability has been identified in Codezips Pet Shop Management System version 1.0. The vulnerability exists in the /deletebird.php file, where improper handling of the t1 parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, bypass authentication, modify database contents, or potentially gain further access to the underlying system through database-level exploits.

Affected Products

• Codezips Pet Shop Management System 1.0

Technical Details for CVE-2024-10431

Vulnerability Analysis

This SQL injection vulnerability occurs due to insufficient input validation in the deletebird.php file within the Codezips Pet Shop Management System. The application fails to properly sanitize user-supplied input in the t1 parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are executed by the database server with the application's privileges.

The vulnerability is particularly concerning because it can be exploited remotely without any authentication requirements. The affected endpoint appears to handle deletion operations, which when exploited could allow attackers to perform unauthorized database operations beyond simple deletions.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries (prepared statements) in the application's database interaction layer. The t1 parameter from user input is directly concatenated into SQL query strings without proper escaping or sanitization, enabling attackers to break out of the intended query structure and inject malicious SQL code.

Attack Vector

The attack is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the /deletebird.php endpoint with specially crafted values in the t1 parameter. By manipulating this parameter, attackers can:

1. Extract sensitive information from the database using UNION-based or blind SQL injection techniques
2. Modify or delete existing records in the database
3. Bypass authentication mechanisms if credentials are stored in accessible tables
4. Potentially execute system commands if the database supports extended stored procedures

The vulnerability is accessible remotely and has been publicly disclosed, meaning exploit details are available. Organizations using this software should treat this as a high-priority security issue requiring immediate attention.

Detection Methods for CVE-2024-10431

Indicators of Compromise

• Unusual or malformed requests to /deletebird.php containing SQL syntax characters such as single quotes, double dashes, or semicolons in the t1 parameter
• Web server logs showing requests with URL-encoded SQL keywords (SELECT, UNION, INSERT, DROP, etc.) in query parameters
• Database logs indicating unexpected query patterns, errors, or unauthorized data access attempts
• Anomalous database performance or unexpected data modifications in pet shop-related tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns targeting the t1 parameter
• Implement application-level logging for all requests to deletebird.php and analyze for suspicious payloads
• Configure database activity monitoring to alert on unusual query structures or unauthorized table access
• Use intrusion detection systems (IDS) with SQL injection signature detection capabilities

Monitoring Recommendations

• Enable detailed access logging on web servers hosting the Pet Shop Management System application
• Monitor database query logs for syntax errors or unexpected query patterns that may indicate injection attempts
• Establish baseline metrics for normal database operations and alert on deviations
• Implement real-time alerting for requests containing common SQL injection payloads to the affected endpoint

How to Mitigate CVE-2024-10431

Immediate Actions Required

• Restrict access to the /deletebird.php endpoint using network-level controls or authentication until a patch is available
• Implement Web Application Firewall (WAF) rules to block SQL injection attempts targeting this endpoint
• Consider taking the application offline if it contains sensitive data and cannot be adequately protected
• Review database permissions and ensure the application database user has minimal required privileges

Patch Information

At the time of publication, no official patch from Codezips has been released for this vulnerability. Organizations using Codezips Pet Shop Management System 1.0 should monitor vendor communications for security updates. For additional technical details, refer to the GitHub CVE Issue Discussion and VulDB entry #281982.

Workarounds

• Implement input validation on the server-side to reject any t1 parameter values containing SQL metacharacters
• Use a reverse proxy or WAF to filter requests containing SQL injection patterns before they reach the application
• Restrict network access to the application to trusted IP addresses only
• If possible, modify the application code to use parameterized queries (prepared statements) for all database operations

# Example: Block access to vulnerable endpoint using Apache .htaccess
<Files "deletebird.php">
    Order deny,allow
    Deny from all
    # Allow only from trusted admin IPs
    Allow from 192.168.1.0/24
</Files>
