CVE-2026-117514 in php-travel-agency-system
Summary
by MITRE • 10/27/2026
A vulnerability was identified in oretnom23 php-travel-agency-system. This issue affects some unknown processing of the file admin/customer_detail.php of the component Admin Record Pages. The manipulation of the argument costomer_id/ticket_id/emp_id/salary_id/page_id leads to sql injection. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The php-travel-agency-system, developed under the identifier oretnom23, contains a critical security flaw within its administrative interface that exposes sensitive backend data to unauthorized access. Specifically, the vulnerability resides in the admin/customer_detail.php file, which serves as part of the Admin Record Pages component responsible for displaying detailed information about customers or related entities. This module is designed to retrieve and present specific records based on user-supplied identifiers passed through HTTP requests. However, the application fails to properly sanitize or validate these inputs before incorporating them into database queries, creating a classic injection point that allows attackers to interfere with the intended logic of the backend SQL operations.
The core technical flaw is an unvalidated input leading to SQL Injection, categorized under CWE-89 in industry standards for software weaknesses. The vulnerability affects multiple identifier parameters including costomer_id, ticket_id, emp_id, salary_id, and page_id. When these arguments are manipulated by a remote attacker, they can inject malicious SQL code into the query structure executed by the database management system. Because the application does not employ parameterized queries or prepared statements to separate code from data, the injected payload is interpreted as part of the command rather than as literal input. This allows an adversary to bypass authentication controls, extract sensitive information such as user credentials and personal customer details, modify existing records, or potentially execute administrative commands on the underlying database server depending on its configuration privileges.
The operational impact of this vulnerability is severe due to the remote nature of the exploit vector. Attackers can initiate these attacks from any location over a network without requiring prior authentication, making it accessible to a wide range of threat actors including automated bots and script kiddies. The fact that public exploits are already available significantly lowers the barrier for entry, increasing the likelihood of successful compromise in environments where this software is deployed with default configurations or unpatched versions. Data exfiltration remains the primary concern, as travel agencies typically store highly sensitive personal identifiable information (PII), payment details, and booking histories. A successful exploitation could lead to significant regulatory penalties under frameworks like GDPR or CCPA due to the breach of customer data privacy obligations.
Mitigation strategies must focus on immediate remediation of the codebase alongside broader security hardening practices. The most effective technical fix involves refactoring all database interaction logic in admin/customer_detail.php and related files to use prepared statements with parameterized queries, ensuring that user-supplied inputs are treated strictly as data rather than executable code. Input validation should also be implemented to enforce strict type checking and length constraints on the affected parameters such as costomer_id and ticket_id. Additionally, since the project maintainers have not yet responded to early reports, organizations currently using this software should consider isolating the administrative interface behind strong access controls like IP whitelisting or multi-factor authentication while awaiting a patch. Long-term resilience requires adopting secure coding standards aligned with OWASP guidelines and conducting regular code reviews to detect similar injection flaws across other components of the application architecture.
