CVE-2026-36923: Cab Management System SQLi Vulnerability

CVE-2026-36923 Overview

CVE-2026-36923 is a SQL Injection vulnerability affecting Sourcecodester Cab Management System version 1.0. The vulnerability exists in the file /cms/admin/bookings/view_booking.php, allowing authenticated attackers with high privileges to inject malicious SQL queries through the network. This security flaw enables unauthorized access to sensitive database information.

Critical Impact

Authenticated administrators can exploit this SQL Injection vulnerability to extract sensitive information from the database, potentially exposing customer booking details, driver information, and other confidential data stored in the Cab Management System.

Affected Products

• Oretnom23 Cab Management System 1.0
• Sourcecodester Cab Management System (/cms/admin/bookings/view_booking.php)

Technical Details for CVE-2026-36923

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs in the administrative booking view functionality of the Cab Management System. The affected endpoint /cms/admin/bookings/view_booking.php fails to properly sanitize user-supplied input before incorporating it into SQL queries, allowing attackers to manipulate database operations.

The vulnerability requires high-level privileges to exploit, meaning an attacker must have administrative access to the system. While this reduces the attack surface, compromised admin accounts or insider threats could leverage this flaw to access data beyond their intended authorization scope.

The exploitation results in confidentiality impact, enabling unauthorized read access to database contents. However, the vulnerability does not directly enable modification of data or denial of service conditions.

Root Cause

The root cause is improper input validation and lack of parameterized queries in the view_booking.php file. User-controlled parameters are directly concatenated into SQL statements without adequate sanitization or use of prepared statements, creating the injection vector.

Attack Vector

The attack is conducted over the network against the web application's administrative interface. An authenticated attacker with administrative privileges can craft malicious HTTP requests containing SQL injection payloads targeting the vulnerable booking view functionality.

The vulnerability mechanism involves manipulation of query parameters in requests to /cms/admin/bookings/view_booking.php. When the application processes these requests, unsanitized input is incorporated directly into database queries, allowing attackers to modify query logic and extract unauthorized data. For detailed technical information, refer to the GitHub SQL Injection Report.

Detection Methods for CVE-2026-36923

Indicators of Compromise

• Unusual SQL error messages appearing in web server logs related to /cms/admin/bookings/view_booking.php
• HTTP requests to the booking view endpoint containing SQL-specific characters such as single quotes, semicolons, or SQL keywords like UNION, SELECT, OR 1=1
• Database logs showing unexpected or malformed queries originating from the booking module
• Abnormal data access patterns from administrative accounts accessing large volumes of booking records

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the administrative booking endpoints
• Implement database activity monitoring to identify anomalous query patterns or unauthorized data extraction attempts
• Configure intrusion detection systems (IDS) to alert on HTTP requests containing SQL injection payloads
• Review web server access logs for suspicious parameter values in requests to /cms/admin/bookings/view_booking.php

Monitoring Recommendations

• Enable detailed logging for all database queries executed by the Cab Management System application
• Monitor administrative user sessions for unusual activity patterns or access to sensitive data
• Set up alerts for SQL error conditions that may indicate injection attempts
• Regularly audit access logs for the /cms/admin/bookings/ directory

How to Mitigate CVE-2026-36923

Immediate Actions Required

• Restrict access to the Cab Management System administrative interface to trusted networks only
• Review and audit all administrative user accounts for unauthorized access
• Consider temporarily disabling the vulnerable booking view functionality until a patch is applied
• Implement additional input validation at the application layer

Patch Information

No official vendor patch is currently available for this vulnerability. System administrators should monitor the Sourcecodester project and community resources for security updates. The vulnerability details are documented in the GitHub SQL Injection Report.

Workarounds

• Implement prepared statements and parameterized queries by modifying the view_booking.php source code directly
• Deploy a Web Application Firewall with SQL injection protection rules in front of the application
• Restrict administrative access to the system using IP whitelisting or VPN requirements
• Apply principle of least privilege by limiting which administrators can access booking functionality

The following configuration demonstrates implementing IP-based access restrictions for the vulnerable administrative directory:

# Apache configuration to restrict admin access
<Directory "/var/www/html/cms/admin/bookings">
    # Allow only trusted IP addresses
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
    
    # Deny all other access
    Require all denied
</Directory>
