CVE-2024-9087: Vehicle Management SQL Injection Flaw

CVE-2024-9087 Overview

A critical SQL injection vulnerability has been identified in code-projects Vehicle Management 1.0. The flaw exists in the /edit1.php file where the sno parameter is improperly handled, allowing attackers to inject malicious SQL statements. This vulnerability can be exploited remotely without authentication, potentially enabling unauthorized database access, data manipulation, and information disclosure.

Critical Impact

Unauthenticated attackers can remotely exploit this SQL injection to access, modify, or delete sensitive vehicle management data, potentially compromising the entire database backend.

Affected Products

• Vehicle Management 1.0 by code-projects
• Systems running /edit1.php with unvalidated sno parameter input

Technical Details for CVE-2024-9087

Vulnerability Analysis

This vulnerability is a classic SQL Injection flaw (CWE-89) affecting the Vehicle Management application. The vulnerable endpoint /edit1.php accepts user-supplied input through the sno parameter without proper sanitization or parameterized query handling. When user input is directly concatenated into SQL queries, attackers can manipulate the query logic to perform unauthorized operations against the backend database.

The vulnerability is remotely exploitable, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads in the sno parameter to extract sensitive information, bypass authentication mechanisms, modify database records, or potentially escalate to further system compromise depending on database permissions and configuration.

Root Cause

The root cause of this vulnerability is insufficient input validation and the use of dynamic SQL query construction. The application fails to implement prepared statements or parameterized queries when processing the sno parameter in /edit1.php. Instead, user-supplied values are directly incorporated into SQL statements, enabling injection attacks.

Attack Vector

The attack can be initiated remotely over the network. An attacker sends crafted HTTP requests to the /edit1.php endpoint with malicious SQL syntax embedded in the sno parameter. Since no authentication is required, any remote attacker with network access to the application can exploit this vulnerability.

The exploitation method involves injecting SQL statements through the vulnerable parameter. For example, attackers may use UNION-based injection to extract data from other tables, boolean-based blind injection to enumerate database contents, or time-based techniques to exfiltrate information when direct output is not available. For technical details about this vulnerability, refer to the GitHub Issue Discussion and VulDB Entry #278265.

Detection Methods for CVE-2024-9087

Indicators of Compromise

• Unusual or malformed requests to /edit1.php containing SQL syntax characters such as single quotes, semicolons, UNION keywords, or comment sequences
• Database error messages in application logs indicating syntax errors from user-supplied input
• Unexpected database queries or access patterns in database audit logs
• Evidence of data exfiltration or unauthorized record modifications in the vehicle management system

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns in the sno parameter
• Monitor HTTP access logs for requests to /edit1.php containing suspicious payloads
• Enable database query logging and alert on queries containing unexpected SQL keywords or syntax
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Review application and web server logs for requests to /edit1.php with anomalous parameter values
• Configure SIEM alerts for patterns matching SQL injection attempts against the Vehicle Management application
• Monitor database performance metrics for unusual query execution times that may indicate time-based blind SQL injection
• Establish baseline traffic patterns to identify anomalous access to the vulnerable endpoint

How to Mitigate CVE-2024-9087

Immediate Actions Required

• Restrict network access to the Vehicle Management application to trusted networks only
• Implement a web application firewall (WAF) with SQL injection protection rules
• Disable or remove the /edit1.php endpoint if not critical to operations
• Review database permissions and apply principle of least privilege to the application database user

Patch Information

No official vendor patch has been identified for this vulnerability at the time of writing. Organizations should contact Code Projects for remediation guidance or implement the workarounds described below.

Workarounds

• Replace dynamic SQL queries with parameterized prepared statements in /edit1.php
• Implement strict input validation to allow only expected numeric values for the sno parameter
• Deploy a web application firewall (WAF) to filter malicious SQL injection payloads
• Restrict access to the application using network segmentation and authentication controls

# Example: Restrict access to vulnerable endpoint via web server configuration (Apache)
# Add to .htaccess or Apache configuration
<Location "/edit1.php">
    Require ip 192.168.1.0/24
    # Or require valid authentication
    AuthType Basic
    AuthName "Restricted Access"
    AuthUserFile /etc/apache2/.htpasswd
    Require valid-user
</Location>
