CVE-2024-10370: Codezips Sales Management System SQLi

CVE-2024-10370 Overview

A SQL Injection vulnerability has been identified in Codezips Sales Management System version 1.0. This critical security flaw affects the /addcustind.php file, where improper handling of the refno parameter allows attackers to inject malicious SQL commands. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, or complete system compromise.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to bypass authentication, extract sensitive customer data, modify database records, or potentially gain full control over the backend database system.

Technical Details for CVE-2024-10370

Vulnerability Analysis

This SQL Injection vulnerability exists in the /addcustind.php endpoint of Codezips Sales Management System. The application fails to properly sanitize or parameterize user input in the refno parameter before incorporating it into SQL queries. This allows attackers to craft malicious input that alters the intended SQL query logic.

The attack is network-accessible, meaning any remote attacker can target vulnerable installations without requiring prior authentication or user interaction. The exploit has been publicly disclosed, increasing the risk of widespread exploitation against unpatched systems.

Root Cause

The root cause of CVE-2024-10370 is the lack of proper input validation and sanitization for the refno parameter in the /addcustind.php file. The application directly concatenates user-supplied input into SQL queries without using prepared statements or parameterized queries. This fundamental coding error allows attacker-controlled data to be interpreted as SQL commands rather than data values.

This vulnerability falls under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), a common weakness where untrusted data is not properly escaped before being passed to an SQL interpreter.

Attack Vector

The vulnerability is exploited via network-based attacks targeting the /addcustind.php endpoint. An attacker can manipulate the refno parameter by injecting SQL metacharacters and commands. The attack requires no authentication and no user interaction, making it trivially exploitable.

A typical attack scenario involves sending crafted HTTP requests to the vulnerable endpoint with SQL injection payloads in the refno parameter. Depending on the database permissions and application configuration, attackers may be able to:

• Extract sensitive data from the database including customer records
• Modify or delete database entries
• Bypass authentication mechanisms
• Escalate privileges within the application
• Potentially execute operating system commands if database features like xp_cmdshell (SQL Server) or INTO OUTFILE (MySQL) are enabled

Technical details and proof-of-concept information are available through the GitHub CVE Issue Discussion and VulDB #281762.

Detection Methods for CVE-2024-10370

Indicators of Compromise

• Unusual HTTP requests to /addcustind.php containing SQL metacharacters such as single quotes, double dashes, or UNION statements in the refno parameter
• Database error messages in application logs indicating malformed SQL queries
• Unexpected database queries in database audit logs, particularly those containing UNION SELECT or other injection patterns
• Anomalous data exfiltration patterns from the database server

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the refno parameter
• Implement database activity monitoring to identify unauthorized queries or data access patterns
• Configure application logging to capture all requests to /addcustind.php with full parameter values
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable verbose logging on the web server for requests to /addcustind.php
• Monitor database query logs for syntax errors or unusual query structures
• Set up alerts for high-volume requests to the vulnerable endpoint from single IP addresses
• Implement real-time monitoring for database exfiltration indicators such as large result sets or access to sensitive tables

How to Mitigate CVE-2024-10370

Immediate Actions Required

• If possible, disable or restrict access to the /addcustind.php file until a patch is available
• Implement network-level access controls to limit who can reach the vulnerable endpoint
• Deploy WAF rules specifically designed to filter SQL injection attempts in the refno parameter
• Conduct a security audit of the database to identify any indicators of prior compromise

Patch Information

At the time of publication, no official patch from Codezips has been documented in the CVE data. Organizations using Codezips Sales Management System 1.0 should contact the vendor directly for patch availability and apply any security updates as soon as they become available.

For the latest vulnerability tracking information, refer to VulDB CTI ID #281762.

Workarounds

• Implement input validation at the application level to reject refno values containing SQL metacharacters
• Use a reverse proxy or WAF to filter malicious requests before they reach the application
• Restrict database user permissions to the minimum required for application functionality, limiting the impact of successful SQL injection
• Consider placing the application behind a VPN or requiring authentication at the network layer to reduce attack surface
