Executive Summary

CVE-2026-6153 is a critical SQL injection vulnerability found in version 1.0 of the Vehicle Showroom Management System, specifically in the file /util/StaffDetailsFunction.php.

The vulnerability occurs because the STAFF_ID parameter is used directly in SQL queries without proper input validation or sanitization, allowing attackers to inject malicious SQL code.

This flaw can be exploited remotely without any authentication or authorization, making it highly accessible to attackers.

Attackers can use various SQL injection techniques such as boolean-based blind, error-based, time-based blind, and UNION query injections to manipulate database queries.

Detection Guidance

The CVE-2026-6153 vulnerability can be detected by testing the vulnerable parameter STAFF_ID for SQL injection flaws using various payloads such as boolean-based blind, error-based, time-based blind, and UNION query injections.

One effective method is to use automated tools like sqlmap to test the parameter for SQL injection vulnerabilities and enumerate the database.

• Example boolean-based blind injection payload: STAFF_ID=-2274' OR 5423=5423#
• Example error-based injection payload: STAFF_ID=111' OR (SELECT 9118 FROM(SELECT COUNT(*),CONCAT(...))a)--
• Example time-based blind injection payload: STAFF_ID=111' AND (SELECT 8555 FROM (SELECT(SLEEP(5)))bnuY)--
• Example UNION query injection payload: STAFF_ID=111' UNION ALL SELECT NULL,NULL,NULL,NULL,CONCAT(...)

Using sqlmap, you can run a command like: sqlmap -u "http://targetsite/util/StaffDetailsFunction.php?STAFF_ID=1" --batch to automate detection.

Mitigation Strategies

Immediate mitigation steps for CVE-2026-6153 include implementing prepared statements with parameter binding to prevent SQL injection by separating SQL code from user input.

Strict input validation and filtering should be enforced to ensure that the STAFF_ID parameter conforms to expected formats and does not contain malicious input.

Minimize database user privileges by avoiding the use of high-privilege accounts such as root or admin for the application’s database connections.

Conduct regular security audits of the code and systems to detect and remediate vulnerabilities promptly.

Compliance Impact

The SQL injection vulnerability in the Vehicle Showroom Management System allows attackers to perform unauthorized database access, extract sensitive information, modify or delete data, and disrupt service availability.

Such unauthorized access and potential data breaches can lead to non-compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data, ensuring data integrity, confidentiality, and availability.

Failure to secure against this vulnerability could result in exposure of personal data, violating data protection requirements and potentially leading to legal and financial penalties under these regulations.
