CVE-2019-25488: Jettweb Hazir Rent SQLi — Patch Guide

Overview

A high-severity security vulnerability, tracked as CVE-2019-25488, has been identified in the Jettweb Hazir Rent A Car Script V4. The flaw consists of multiple SQL injection vulnerabilities within the software’s admin panel. These vulnerabilities allow attackers to interfere with the application’s database queries without needing login credentials, posing a significant risk to data confidentiality and system availability.

Vulnerability Details

The vulnerability exists in the admin/index.php endpoint. Specifically, the tur, id, and ozellikdil parameters passed via HTTP GET requests are not properly sanitized. An unauthenticated attacker can craft malicious requests containing SQL code within these parameters. When processed by the application, this injected code is executed directly against the underlying database. This allows an attacker to read, modify, or delete database contents, including sensitive information like customer data, administrative credentials, and business records.

Potential Impact

The impact of successful exploitation is severe. Attackers can:

• Extract Sensitive Data: Steal the entire database contents, leading to a major data breach. For information on real-world breaches, you can review public breach reports.
• Cause Denial of Service: Manipulate or corrupt database tables, rendering the car rental application unusable.
• Compromise Admin Controls: Potentially access or create administrative accounts to gain full control over the application.

This flaw received a CVSS score of 8.2 (HIGH), reflecting its potential for significant damage with low attack complexity.

Remediation and Mitigation

Immediate action is required to secure affected systems.

Primary Remediation: The most effective solution is to update to a patched version of the software. Contact the vendor (Jettweb) to obtain the latest, secured version of Hazir Rent A Car Script. If a direct patch is unavailable, consider migrating to a supported and actively maintained alternative platform.

Immediate Mitigations: If an immediate update is not possible, apply these temporary measures:

1. Input Validation and Sanitization: Implement strict allow-list input validation on the server-side for all user-supplied data, especially the tur, id, and ozellikdil parameters. Reject any input that does not match an expected pattern (e.g., only numeric characters for an ID).
2. Use Prepared Statements: Rewrite the database queries using parameterized prepared statements with bound variables. This is the most reliable coding practice to prevent SQL injection.
3. Network Restriction: Restrict access to the admin panel (/admin/) by IP address using a web application firewall (WAF) or server configuration, limiting it to only trusted administrative networks.

Stay informed about emerging threats by following the latest security news. Organizations using this software should audit their systems for signs of compromise and assume credentials stored in the database may be exposed.
