CVE-2024-8259: NatraCar B2B SQL Injection Vulnerability

CVE-2024-8259 Overview

CVE-2024-8259 is a critical SQL Injection vulnerability affecting Eryaz Information Technologies NatraCar B2B Dealer Management Program. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing attackers to inject malicious SQL queries and potentially gain unauthorized access to backend databases.

This issue is particularly concerning because the vendor has confirmed that the affected product is no longer supported, meaning no security patches will be released to address this vulnerability.

Critical Impact

This SQL Injection vulnerability allows unauthenticated remote attackers to execute arbitrary SQL commands against the database, potentially leading to complete data breach, data manipulation, or system compromise. The product is end-of-life with no patches available.

Affected Products

• NatraCar B2B Dealer Management Program (all versions through 09.12.2024)
• Eryaz Information Technologies NatraCar B2B platform deployments

Technical Details for CVE-2024-8259

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists in the NatraCar B2B Dealer Management Program, a business-to-business platform used for dealer management operations. The vulnerability allows attackers to manipulate SQL queries by injecting specially crafted input that is not properly sanitized before being included in database operations.

SQL Injection attacks exploit the lack of proper input validation, enabling attackers to bypass authentication mechanisms, extract sensitive data from databases, modify or delete records, and in some cases execute commands on the underlying operating system. The network-accessible nature of this vulnerability combined with no authentication requirements makes it particularly dangerous for organizations running this software.

Root Cause

The root cause of CVE-2024-8259 is the failure to properly sanitize or parameterize user-supplied input before incorporating it into SQL queries. The application directly concatenates user input into SQL statements without using prepared statements, parameterized queries, or adequate input validation. This allows special SQL characters and commands to be interpreted as part of the database query rather than as literal data.

Attack Vector

The vulnerability is exploitable over the network without requiring authentication or user interaction. An attacker can target web application endpoints that accept user input and pass it to backend database queries. By crafting malicious input containing SQL syntax, attackers can manipulate query logic to extract data, bypass authentication, or perform unauthorized database operations.

Common attack techniques include using SQL UNION statements to retrieve data from other tables, boolean-based blind injection to enumerate database contents character by character, and time-based blind injection to confirm vulnerability presence when no direct output is visible.

Detection Methods for CVE-2024-8259

Indicators of Compromise

• Unusual database queries in application logs containing SQL keywords like UNION, SELECT, OR 1=1, or comment sequences (--, /*)
• Failed login attempts with suspicious characters in username or password fields
• Abnormal database traffic patterns or query execution times
• Unexpected data extraction or large result sets in database audit logs
• Web application firewall alerts for SQL injection patterns

Detection Strategies

• Deploy web application firewalls (WAF) with SQL injection rule sets to detect and block malicious requests
• Enable comprehensive database query logging and monitor for anomalous SQL patterns
• Implement intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
• Review web server access logs for requests containing encoded SQL characters or injection payloads

Monitoring Recommendations

• Configure real-time alerting for database queries containing suspicious SQL constructs
• Monitor application error logs for database syntax errors that may indicate injection attempts
• Implement rate limiting on authentication endpoints to slow down automated injection testing
• Track and alert on unusual data access patterns from the application database user account

How to Mitigate CVE-2024-8259

Immediate Actions Required

• Assess whether NatraCar B2B Dealer Management Program is deployed in your environment
• If the vulnerable software is in use, plan immediate migration to an actively supported alternative solution
• Implement network segmentation to restrict access to the vulnerable application from untrusted networks
• Deploy a web application firewall (WAF) with SQL injection protection rules as an interim measure
• Disable or remove the application if it is no longer business-critical

Patch Information

No security patch is available for this vulnerability. The vendor (Eryaz Information Technologies) has confirmed that the NatraCar B2B Dealer Management Program is no longer supported. Organizations using this software must migrate to an alternative solution to address this security risk.

For additional information, refer to the USOM Security Notification.

Workarounds

• Place the application behind a reverse proxy with strict input validation and SQL injection filtering
• Restrict network access to the application using firewall rules, limiting it to trusted IP addresses only
• Implement database user account restrictions to minimize the impact of potential SQL injection attacks
• Consider deploying database activity monitoring to detect and alert on suspicious query patterns
• Accelerate migration planning to replace the unsupported software with a maintained alternative

# Example: Restrict network access to vulnerable application
# Add firewall rules to limit access to trusted networks only
iptables -A INPUT -p tcp --dport 80 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
