CVE-2019-25488: Jettweb Rent A Car Script SQLi Flaw

CVE-2019-25488 Overview

Jettweb Hazir Rent A Car Scripti V4 contains multiple SQL injection vulnerabilities in the admin panel that allow unauthenticated attackers to manipulate database queries through GET parameters. Attackers can inject SQL code into the tur, id, and ozellikdil parameters of the admin/index.php endpoint to extract sensitive database information or cause denial of service.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive database contents, modify data, or potentially achieve complete database compromise through the publicly accessible admin panel.

Technical Details for CVE-2019-25488

Vulnerability Analysis

This vulnerability is classified as SQL Injection (CWE-89), a critical web application security flaw that occurs when user-supplied input is incorporated into SQL queries without proper sanitization or parameterization. The affected component is the admin panel of the Jettweb Hazir Rent A Car Scripti V4 application, specifically the admin/index.php endpoint.

The vulnerability allows network-based attacks without requiring authentication or user interaction, making it highly accessible to remote attackers. The impact primarily affects data confidentiality and integrity, enabling unauthorized access to sensitive database information stored by the application.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries in the admin panel's database interaction logic. The application directly concatenates user-supplied GET parameters (tur, id, and ozellikdil) into SQL query strings without sanitizing special characters or using prepared statements. This classic SQL injection pattern allows attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack vector is network-based, targeting the admin/index.php endpoint via HTTP GET requests. An attacker can craft malicious URLs containing SQL injection payloads in the vulnerable parameters. Since no authentication is required to exploit this flaw, any remote attacker with network access to the application can attempt exploitation.

The vulnerable parameters (tur, id, and ozellikdil) appear to be used for filtering or selecting records in the admin interface. By injecting SQL syntax such as single quotes, UNION SELECT statements, or boolean-based payloads, attackers can:

• Extract database schema information and table contents
• Retrieve user credentials and other sensitive data
• Modify or delete database records
• Potentially escalate to command execution depending on database configuration

For detailed technical information and proof-of-concept examples, refer to the Exploit-DB #46614 entry and the VulnCheck Advisory on JettWeb SQL Injection.

Detection Methods for CVE-2019-25488

Indicators of Compromise

• Unusual or malformed requests to admin/index.php containing SQL syntax characters such as single quotes, double dashes, or UNION statements in the tur, id, or ozellikdil parameters
• Unexpected database errors in application logs indicating SQL syntax issues
• Anomalous database query patterns including SELECT statements with UNION clauses or information_schema references
• Evidence of bulk data extraction or unauthorized access to administrative functions

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in GET parameters
• Implement intrusion detection signatures for SQL injection attempts targeting the admin/index.php endpoint
• Monitor HTTP access logs for requests containing encoded or plaintext SQL keywords in URL parameters
• Enable database query logging and alert on queries with suspicious patterns such as excessive SELECT statements or schema enumeration

Monitoring Recommendations

• Configure real-time alerting for requests to the admin panel containing SQL injection indicators
• Establish baseline traffic patterns for the admin interface and alert on anomalous access volumes
• Monitor database user activity for unauthorized SELECT operations on sensitive tables
• Review application error logs regularly for SQL-related exceptions or syntax errors

How to Mitigate CVE-2019-25488

Immediate Actions Required

• Restrict network access to the admin panel using IP allowlisting or VPN requirements
• Deploy a Web Application Firewall with SQL injection prevention rules in front of the application
• Consider taking the affected application offline until a proper fix can be implemented
• Audit database logs for evidence of prior exploitation attempts

Patch Information

No vendor patch information is currently available for this vulnerability. The Jettweb Hazir Rent A Car Scripti V4 application does not appear to have an active vendor response. Organizations using this software should implement compensating controls and consider migrating to a maintained alternative.

For additional context, consult the Exploit-DB #46614 entry and the VulnCheck Advisory.

Workarounds

• Implement input validation at the web server level using ModSecurity or similar WAF solutions to filter malicious characters from the tur, id, and ozellikdil parameters
• Use .htaccess or web server configuration to restrict admin panel access to trusted IP addresses only
• If source code access is available, modify the vulnerable code to use parameterized queries or prepared statements
• Place the application behind an authenticating reverse proxy to prevent unauthenticated access to the admin endpoint

# Example Apache .htaccess configuration to restrict admin access
<Directory "/var/www/html/admin">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Directory>
