CVE-2024-10167: Codezips Sales Management System SQLi

CVE-2024-10167 Overview

A SQL injection vulnerability has been identified in Codezips Sales Management System 1.0. This critical flaw exists in the deletecustind.php file, where the id parameter is not properly sanitized before being used in database queries. The vulnerability allows remote attackers to inject malicious SQL statements, potentially leading to unauthorized data access, modification, or deletion of database contents.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive customer data, modify database records, or potentially gain further access to the underlying system through database exploitation techniques.

Technical Details for CVE-2024-10167

Vulnerability Analysis

This vulnerability is classified as CWE-89 (SQL Injection), a well-documented web application security flaw. The affected component, deletecustind.php, accepts user-supplied input through the id parameter without adequate validation or sanitization. When this input is incorporated directly into SQL queries, it enables attackers to manipulate the query structure and execute arbitrary SQL commands against the backend database.

The network-accessible nature of this vulnerability means that attackers do not require local access or prior authentication to exploit the flaw. Sales management systems typically contain sensitive business data including customer information, transaction records, and potentially financial data, making this an attractive target for malicious actors.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries in the deletecustind.php file. The id parameter is likely concatenated directly into SQL statements without sanitization, allowing special characters and SQL syntax to be interpreted as part of the query rather than as literal data values. This represents a fundamental secure coding violation where user input is trusted without verification.

Attack Vector

The attack vector is network-based, requiring no user interaction or special privileges. An attacker can craft malicious HTTP requests containing SQL injection payloads in the id parameter. Common exploitation techniques include:

The vulnerability can be exploited by appending SQL operators and statements to the id parameter value. For example, an attacker might modify the parameter to include UNION-based injection payloads to extract data from other tables, or use boolean-based blind injection techniques to enumerate database contents character by character. Time-based blind injection using functions like SLEEP() can also be employed when direct output is not available.

Detection Methods for CVE-2024-10167

Indicators of Compromise

• Unusual HTTP requests to deletecustind.php containing SQL syntax characters such as single quotes, double dashes, UNION keywords, or encoded equivalents
• Database error messages appearing in web server logs or application responses
• Unexpected database queries or query patterns in database audit logs
• Anomalous data access patterns or bulk data retrieval from customer-related tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the id parameter
• Deploy database activity monitoring to identify suspicious query patterns or unauthorized data access attempts
• Configure intrusion detection systems (IDS) to alert on HTTP traffic containing SQL injection signatures directed at PHP endpoints
• Enable verbose logging on the web server to capture request parameters for forensic analysis

Monitoring Recommendations

• Monitor access logs for requests to deletecustind.php with anomalous or oversized parameter values
• Set up alerts for database errors that may indicate injection attempts
• Track and baseline normal application behavior to identify deviations indicative of exploitation
• Implement real-time log analysis to correlate suspicious web requests with database activity

How to Mitigate CVE-2024-10167

Immediate Actions Required

• Restrict network access to the Sales Management System to trusted IP addresses only
• Implement a Web Application Firewall with SQL injection protection rules
• Consider temporarily disabling the deletecustind.php functionality if not business-critical
• Review and audit all user-facing PHP files for similar SQL injection vulnerabilities

Patch Information

As of the last NVD update on 2024-10-21, no official vendor patch has been documented for this vulnerability. Organizations using Codezips Sales Management System 1.0 should contact the vendor directly for remediation guidance or consider implementing the workarounds below. Monitor VulDB for updates on available patches.

Workarounds

• Implement prepared statements (parameterized queries) in the affected deletecustind.php file to properly separate SQL code from user data
• Apply input validation to ensure the id parameter only accepts expected integer values
• Deploy a reverse proxy or WAF to filter malicious requests before they reach the application
• Limit database user privileges to reduce the impact of successful exploitation

# Example WAF rule for ModSecurity to block SQL injection attempts
SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Detected in id parameter',log"
