CVE-2026-36922: Cab Management System SQLi Vulnerability

CVE-2026-36922 Overview

CVE-2026-36922 is a SQL Injection vulnerability affecting Sourcecodester Cab Management System v1.0. The vulnerability exists in the file /cms/admin/categories/view_category.php, which fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows authenticated administrators to manipulate database queries and potentially extract sensitive information from the underlying database.

Critical Impact

Authenticated attackers with administrative privileges can exploit this SQL injection vulnerability to read sensitive data from the database, potentially exposing user credentials, personal information, and other confidential records stored in the Cab Management System.

Affected Products

• Oretnom23 Cab Management System v1.0
• Applications using cpe:2.3:a:oretnom23:cab_management_system:1.0:*:*:*:*:*:*:*

Technical Details for CVE-2026-36922

Vulnerability Analysis

This vulnerability is classified as CWE-89 (SQL Injection), a prevalent web application security flaw. The affected endpoint /cms/admin/categories/view_category.php processes user input without adequate sanitization, allowing malicious SQL code to be injected into database queries. While the vulnerability requires high privileges (administrative access) to exploit, it still poses a risk to data confidentiality within the application.

The attack is network-accessible and requires no user interaction, though the high privilege requirement limits the practical exploitability. The impact is primarily on confidentiality, allowing unauthorized read access to database contents.

Root Cause

The root cause of this vulnerability is improper input validation in the view_category.php file. The application directly concatenates or incorporates user-controlled parameters into SQL query strings without using parameterized queries or prepared statements. This lack of input sanitization allows attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The vulnerability is exploited via network requests to the administrative interface. An attacker with administrative credentials can craft malicious HTTP requests containing SQL injection payloads in parameters processed by the view_category.php script. These payloads manipulate the SQL query logic to extract data, enumerate database schema, or access records beyond the intended scope.

The vulnerability is documented in a GitHub Security Bug Report which provides additional technical details about the exploitation mechanism.

Detection Methods for CVE-2026-36922

Indicators of Compromise

• Unusual SQL error messages in application logs from the /cms/admin/categories/view_category.php endpoint
• Anomalous database query patterns containing SQL injection keywords such as UNION SELECT, OR 1=1, or comment sequences (--, /**/)
• Unexpected access to category-related data by administrative accounts
• Database audit logs showing queries with unusual structure or timing patterns

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block common SQL injection patterns in requests to the Cab Management System
• Monitor HTTP access logs for requests to /cms/admin/categories/view_category.php containing suspicious characters or SQL keywords
• Enable database query logging and alert on malformed or unusually complex queries originating from the web application
• Deploy application-level security monitoring to detect parameter tampering attempts

Monitoring Recommendations

• Configure SIEM alerts for SQL injection signature matches in web server logs
• Enable detailed logging for the Cab Management System administrative interface
• Implement database activity monitoring to track unusual query patterns or data access
• Review administrative account activity for anomalous behavior patterns

How to Mitigate CVE-2026-36922

Immediate Actions Required

• Restrict access to the administrative interface to trusted networks or IP addresses only
• Implement additional authentication controls for administrative functions
• Deploy a web application firewall with SQL injection detection rules
• Review and audit all administrative account access and activity logs
• Consider taking the affected application offline until a patch is available

Patch Information

No official patch has been released by the vendor at this time. The vulnerability was disclosed via a GitHub Security Bug Report. Organizations using the Sourcecodester Cab Management System should monitor for updates from the developer and apply patches when available.

Workarounds

• Implement input validation and parameterized queries in the view_category.php file if source code modification is possible
• Use a reverse proxy or WAF to filter incoming requests and block SQL injection attempts
• Limit database user privileges for the application to minimum required permissions (principle of least privilege)
• Isolate the application database to prevent lateral movement if the vulnerability is exploited
• Implement network segmentation to restrict administrative interface access to authorized personnel only
