CVE-2024-6218: Admerc Vehicle Management System SQL Injection

CVE-2024-6218 Overview

A critical SQL injection vulnerability has been identified in itsourcecode Vehicle Management System version 1.0. The vulnerability exists in the busprofile.php file, where improper handling of the busid parameter allows attackers to inject malicious SQL queries. This flaw enables unauthenticated remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability without authentication to extract sensitive data, modify database records, or potentially compromise the underlying server through database-specific exploitation techniques.

Technical Details for CVE-2024-6218

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) affects the busprofile.php file within the Vehicle Management System application. The vulnerability stems from insufficient input validation and sanitization of user-supplied data passed through the busid parameter. When a user provides input to this parameter, the application directly incorporates it into SQL queries without proper escaping or parameterization, creating a classic SQL injection attack surface.

The vulnerability is network-accessible and requires no authentication or user interaction to exploit. An attacker can craft malicious HTTP requests containing SQL injection payloads in the busid parameter to manipulate the backend database queries. Successful exploitation could allow attackers to read sensitive information from the database, modify or delete data, and potentially execute administrative operations on the database server.

Root Cause

The root cause of CVE-2024-6218 is the lack of proper input validation and parameterized queries in the busprofile.php file. The application directly concatenates user input from the busid parameter into SQL statements without sanitization, escaping, or the use of prepared statements. This classic coding error violates secure development practices and allows attackers to break out of the intended query structure.

Attack Vector

The attack vector is network-based, allowing remote exploitation without authentication. An attacker can send specially crafted HTTP requests to the busprofile.php endpoint with malicious SQL payloads in the busid parameter. The attack requires no user interaction and can be automated for mass exploitation.

The exploitation technique involves appending SQL syntax to the busid parameter value. Common attack patterns include UNION-based injection to extract data from other tables, boolean-based blind injection to infer database contents, and time-based blind injection for scenarios where output is not directly visible. The public disclosure of this vulnerability and its exploitation details increases the risk of widespread attacks against unpatched systems.

Detection Methods for CVE-2024-6218

Indicators of Compromise

• Unusual or malformed requests to busprofile.php containing SQL syntax characters such as single quotes, UNION statements, or comment sequences
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database queries or access patterns in database audit logs
• Web server access logs showing suspicious requests with encoded SQL payloads targeting the busid parameter

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in HTTP requests
• Implement application-level logging to capture and alert on requests containing SQL metacharacters
• Configure database activity monitoring to detect anomalous query patterns or unauthorized data access
• Use intrusion detection systems with signatures for SQL injection attack patterns

Monitoring Recommendations

• Enable verbose logging for the Vehicle Management System application and review logs regularly for suspicious activity
• Monitor database server logs for failed query attempts or unusual query structures
• Set up alerts for requests to busprofile.php with unusual parameter lengths or special characters
• Implement security information and event management (SIEM) correlation rules for SQL injection detection

How to Mitigate CVE-2024-6218

Immediate Actions Required

• Restrict network access to the Vehicle Management System application to trusted IP addresses only
• Implement web application firewall rules to filter SQL injection attempts targeting the busid parameter
• Review application logs and database audit logs for signs of prior exploitation
• Consider taking the application offline if patches are not immediately available and the system processes sensitive data

Patch Information

No official vendor patch information is currently available for this vulnerability. Organizations using the affected Vehicle Management System should contact the vendor for remediation guidance. In the absence of a vendor patch, implementing defense-in-depth measures and considering alternative software solutions is recommended. For additional technical details, refer to the GitHub Issue on CVE and VulDB #269282.

Workarounds

• Implement input validation at the application level to reject requests containing SQL metacharacters in the busid parameter
• Deploy a web application firewall with SQL injection protection enabled in front of the application
• Use database user accounts with minimal privileges for the application to limit the impact of successful exploitation
• Consider implementing stored procedures with parameterized inputs as a code-level workaround if source code access is available
