CVE-2024-10165: Codezips Sales Management System SQLi

CVE-2024-10165 Overview

A SQL Injection vulnerability has been identified in Codezips Sales Management System version 1.0. The vulnerability exists in the deletecustcom.php file, where improper handling of the id 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 bypass authentication, extract sensitive data, modify database records, or potentially gain further access to the underlying system through database manipulation techniques.

Affected Products

• Codezips Sales Management System 1.0
• deletecustcom.php component

Technical Details for CVE-2024-10165

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) affects the deletecustcom.php file within Codezips Sales Management System. The vulnerability occurs when user-supplied input through the id parameter is directly incorporated into SQL queries without proper sanitization or parameterization. This allows attackers to craft malicious input that alters the intended SQL query logic.

The attack can be executed remotely over the network without requiring prior authentication or user interaction. An attacker can leverage this vulnerability to perform various database operations including data extraction, data manipulation, authentication bypass, or even command execution depending on the database configuration and privileges.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries (prepared statements) in the deletecustcom.php file. When the application receives the id parameter, it appears to concatenate this value directly into SQL statements rather than using proper escaping or parameterized queries. This failure to treat user input as untrusted data allows SQL meta-characters to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The vulnerability is exploitable via network-based attacks targeting the deletecustcom.php endpoint. An attacker would craft HTTP requests containing malicious SQL payloads within the id parameter. The exploitation does not require authentication or user interaction, making it accessible to any remote attacker who can reach the vulnerable application.

Typical attack scenarios include:

• Data Exfiltration: Using UNION-based or error-based injection to extract database contents
• Authentication Bypass: Manipulating queries to bypass login controls
• Data Manipulation: Modifying or deleting records through injected UPDATE or DELETE statements
• Privilege Escalation: Extracting administrator credentials or creating new admin accounts

The vulnerability has been publicly disclosed, meaning exploit information is available to potential attackers. For technical details and proof-of-concept information, refer to the GitHub CVE Issue Discussion.

Detection Methods for CVE-2024-10165

Indicators of Compromise

• Unusual or malformed requests to deletecustcom.php containing SQL syntax patterns
• Error messages in application logs revealing SQL query structures
• Unexpected database query patterns or execution times
• Anomalous data access or modification events in database audit logs

Detection Strategies

• Monitor web application logs for requests to deletecustcom.php containing SQL keywords (UNION, SELECT, OR, AND, --, ', etc.)
• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns
• Enable database query logging and alert on suspicious query patterns
• Deploy intrusion detection systems (IDS) with SQL injection signature rules

Monitoring Recommendations

• Enable detailed logging for all requests to the Sales Management System application
• Configure real-time alerting for SQL injection attempt patterns in web server logs
• Monitor database server logs for unusual query patterns or errors
• Implement network traffic analysis to identify potential exploitation attempts

How to Mitigate CVE-2024-10165

Immediate Actions Required

• Restrict access to the vulnerable deletecustcom.php file until a patch is available
• Implement Web Application Firewall (WAF) rules to filter SQL injection attempts
• Review and audit all user accounts and database records for signs of compromise
• Consider taking the application offline if it handles sensitive data and no immediate fix is available

Patch Information

As of the last update on 2024-10-21, no official patch has been released by Codezips for this vulnerability. Organizations using the affected Sales Management System should contact the vendor directly for remediation guidance. In the absence of an official patch, implementing the workarounds below is strongly recommended.

For additional technical details, refer to VulDB #280951 and the VulDB Submission #425636.

Workarounds

• Implement input validation to restrict the id parameter to numeric values only
• Deploy a Web Application Firewall (WAF) configured to block SQL injection patterns
• Use network-level access controls to limit access to the application to trusted IP addresses only
• If possible, modify the application code to use parameterized queries (prepared statements)
• Disable or remove the deletecustcom.php file if the functionality is not critical

# Example: Restrict access to deletecustcom.php using Apache .htaccess
# Add to .htaccess in the application directory
<Files "deletecustcom.php">
    Order Deny,Allow
    Deny from all
    # Allow only from trusted IP addresses if needed
    # Allow from 192.168.1.0/24
</Files>
