CVE-2019-25482: Jettweb Rent A Car Script SQL Injection

CVE-2019-25482 Overview

Jettweb PHP Hazir Rent A Car Sitesi Scripti V2 contains a critical SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the arac_kategori_id parameter. Attackers can send POST requests to the endpoint with malicious SQL payloads to extract sensitive database information, potentially compromising the entire application database.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability to extract, modify, or delete sensitive database information including customer data, credentials, and business records without any authentication requirements.

Technical Details for CVE-2019-25482

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists in the Jettweb PHP Hazir Rent A Car Sitesi Scripti V2, a PHP-based car rental website script. The vulnerability stems from improper handling of user-supplied input in the arac_kategori_id parameter, which is directly incorporated into SQL queries without adequate sanitization or parameterization.

The network-accessible nature of this vulnerability significantly increases its risk profile, as attackers can exploit it remotely without requiring any prior authentication. The vulnerability allows attackers to achieve high confidentiality impact by extracting sensitive database contents and low integrity impact by potentially modifying database records.

Root Cause

The root cause of this vulnerability is insufficient input validation and the failure to use parameterized queries or prepared statements when handling the arac_kategori_id parameter. The application directly concatenates user input into SQL query strings, creating a classic SQL injection attack surface. This violates secure coding practices that mandate proper input sanitization and the use of parameterized database queries.

Attack Vector

The attack is executed remotely over the network by sending specially crafted POST requests to the vulnerable endpoint. The attacker injects malicious SQL code through the arac_kategori_id parameter, which is then processed by the database server as part of the query. No authentication is required, making this vulnerability easily exploitable by any attacker with network access to the application.

The exploitation technique involves crafting SQL payloads that manipulate the intended query logic, potentially using UNION-based injection, boolean-based blind injection, or time-based blind injection techniques to extract database information. Technical details and proof-of-concept information are available in the Exploit-DB #46624 advisory.

Detection Methods for CVE-2019-25482

Indicators of Compromise

• Unusual database query patterns or errors in application logs containing SQL syntax
• POST requests to car rental endpoints with suspicious characters in the arac_kategori_id parameter such as single quotes, UNION statements, or OR conditions
• Unexpected database response times indicating time-based SQL injection attempts
• Evidence of data exfiltration or unauthorized database access in audit logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in POST request parameters
• Monitor application logs for SQL syntax errors or unusual database query patterns
• Deploy database activity monitoring to detect anomalous query structures or unauthorized data access
• Utilize intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging on database servers to capture all query activity and errors
• Configure alerts for repeated failed database queries or syntax errors from the same source
• Monitor for unusual outbound data transfers that may indicate successful data exfiltration
• Review web server access logs for patterns of requests targeting the vulnerable parameter

How to Mitigate CVE-2019-25482

Immediate Actions Required

• Take the affected Jettweb PHP Hazir Rent A Car Sitesi Scripti V2 application offline if possible until remediation is complete
• Implement Web Application Firewall (WAF) rules to block SQL injection attempts targeting the arac_kategori_id parameter
• Review database access logs for evidence of prior exploitation attempts
• Restrict network access to the application to trusted IP ranges if feasible

Patch Information

No official vendor patch information is available for this vulnerability. Organizations using this software should contact Jettweb directly for remediation guidance or consider migrating to a more actively maintained solution. For technical details, refer to the Vulncheck Advisory.

Workarounds

• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the application
• Modify the application source code to implement parameterized queries or prepared statements for all database interactions involving user input
• Implement strict input validation on the arac_kategori_id parameter to only accept expected numeric values
• Consider using a virtual patching solution to filter malicious requests while awaiting a permanent fix

# Example WAF rule for ModSecurity to block SQL injection in arac_kategori_id
