CVE-2024-10556: Pet Shop Management System SQLi Flaw

CVE-2024-10556 Overview

A critical SQL injection vulnerability has been identified in Codezips Pet Shop Management System version 1.0. The vulnerability exists in the birdsadd.php file, where the id parameter is not properly sanitized before being used in SQL queries. This flaw allows remote attackers to execute arbitrary SQL commands against the underlying database, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive database information, modify or delete records, and potentially compromise the entire application database without requiring any authentication.

Affected Products

Technical Details for CVE-2024-10556

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) affects the birdsadd.php file within the Codezips Pet Shop Management System. The vulnerability stems from improper neutralization of special elements used in SQL commands. When user-supplied input is passed through the id parameter, it is directly incorporated into database queries without adequate sanitization or parameterization.

The attack is network-accessible, meaning remote attackers can exploit this vulnerability without requiring any prior authentication or user interaction. The exploit has been publicly disclosed, increasing the risk of exploitation in the wild.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) in the birdsadd.php file. The application directly concatenates user-supplied input from the id parameter into SQL query strings, allowing attackers to inject malicious SQL syntax that alters the intended query logic.

Attack Vector

The vulnerability can be exploited remotely over the network. An attacker can craft malicious HTTP requests to the birdsadd.php endpoint, injecting SQL code through the id parameter. This can be accomplished using standard web attack tools or even a simple web browser.

The vulnerability allows for various SQL injection techniques including:

• Union-based injection to extract data from other tables
• Boolean-based blind injection to infer database contents
• Time-based blind injection for environments where direct output is not visible
• Error-based injection leveraging database error messages

Technical details and proof-of-concept information can be found in the GitHub CVE Issue Discussion and VulDB entry #282558.

Detection Methods for CVE-2024-10556

Indicators of Compromise

• Unusual or malformed HTTP requests targeting birdsadd.php with suspicious id parameter values
• Database query errors appearing in application logs containing SQL syntax
• Unexpected database queries or access patterns, especially those containing UNION, SELECT, or comment sequences
• Authentication bypass events or unauthorized access to administrative functions

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in HTTP requests to the application
• Monitor database query logs for anomalous queries containing injection signatures such as single quotes, double dashes, or UNION statements
• Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
• Review web server access logs for requests to birdsadd.php with encoded characters or unusually long parameter values

Monitoring Recommendations

• Enable detailed logging on the web server and database to capture all queries and requests
• Configure alerts for failed authentication attempts and unusual database activity
• Implement real-time monitoring of application endpoints, particularly birdsadd.php
• Establish baseline traffic patterns and alert on deviations that may indicate exploitation attempts

How to Mitigate CVE-2024-10556

Immediate Actions Required

• Restrict network access to the Pet Shop Management System to trusted IP addresses only
• Consider temporarily disabling or removing the birdsadd.php file if the functionality is not critical
• Implement Web Application Firewall rules to block requests containing SQL injection patterns targeting the id parameter
• Review and audit all user accounts and database records for signs of unauthorized access or modification

Patch Information

At the time of publication, no official patch has been released by Codezips for this vulnerability. Organizations using the affected software should contact the vendor for remediation guidance or consider the workarounds listed below. Monitor VulDB entry #282558 and vendor channels for patch availability updates.

Workarounds

• Implement parameterized queries (prepared statements) in the birdsadd.php file to prevent SQL injection
• Apply strict input validation to the id parameter, accepting only expected numeric values
• Deploy a Web Application Firewall (WAF) configured to detect and block SQL injection attempts
• Restrict database user permissions to limit the potential impact of successful exploitation
• Consider migrating to a more actively maintained pet shop management solution if patches are not forthcoming
