CVE-2026-114440 in php-travel-agency-system
Summary
by MITRE • 10/23/2026
A vulnerability was identified in oretnom23 php-travel-agency-system. This affects an unknown part of the file admin/delete.php. The manipulation of the argument costomer_id/ticket_id/payment_id/id/document_id/salary_id/emp_id/user_id leads to sql injection. The attack can be initiated remotely. The exploit is publicly available and might be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. The project was informed of the problem early through an issue report but has not responded yet.

Analysis

The php-travel-agency-system developed under the oretnom23 identifier contains a critical security flaw within its administrative interface, specifically located in the admin/delete.php script. This vulnerability manifests as a SQL injection weakness resulting from insufficient input validation and sanitization of user-supplied data. The system accepts multiple distinct identifiers including costomer_id, ticket_id, payment_id, id, document_id, salary_id, emp_id, and user_id without adequate protection against malicious payload insertion. These parameters are directly concatenated into database queries executed by the backend application logic, allowing an attacker to manipulate the structure of SQL statements intended for data deletion or retrieval operations within the travel agency management system.
The technical nature of this flaw aligns with CWE-89, which classifies improper neutralization of special elements used in an SQL command. By injecting crafted SQL code through any of the aforementioned identifier parameters, a remote attacker can bypass authentication mechanisms, extract sensitive data from the database such as customer credentials or financial records, modify existing entries, or potentially execute administrative commands depending on the privileges assigned to the database user account running the application. The vulnerability is exploitable remotely over standard network protocols, requiring no prior access to the system beyond what a legitimate visitor might possess through public-facing endpoints that route requests to this deletion script.
Operational impact of this vulnerability extends across confidentiality, integrity, and availability dimensions for organizations deploying this software. Immediate exploitation could lead to unauthorized disclosure of proprietary business data including client personal information, payment histories, and employee records which may violate regulatory compliance frameworks such as GDPR or HIPAA depending on the jurisdiction and data types involved. Furthermore, attackers can alter or delete critical operational records disrupting service continuity and causing significant reputational damage. Since continuous delivery with rolling releases is employed by this project versioning strategy precludes precise identification of affected versions making traditional patch management approaches ineffective for users relying on static version numbers to assess risk exposure.
The exploit code being publicly available significantly lowers the barrier to entry for malicious actors increasing the likelihood of automated scanning and opportunistic attacks targeting instances where this software is deployed without adequate compensating controls. Despite early notification via issue reporting channels, the project maintainers have not yet provided a response or issued corrective updates leaving current deployments in a vulnerable state indefinitely until community-driven fixes or manual interventions are implemented by system administrators responsible for maintaining these environments.
Mitigation strategies must focus on immediate defensive measures since no official patch exists at this time. Administrators should implement web application firewall rules that detect and block common SQL injection patterns within the identified parameter names before they reach the backend processing logic. Input validation should be enforced strictly ensuring only expected integer formats are accepted for all identifier fields with strict type checking applied server-side rather than relying solely on client-side restrictions. Additionally, employing prepared statements or parameterized queries in future code revisions will fundamentally resolve this class of vulnerability by separating SQL logic from data inputs preventing interpretation of injected characters as executable commands.
Access control mechanisms should be reviewed to ensure that the delete functionality is restricted exclusively to authenticated administrators with appropriate privilege levels and protected behind multi-factor authentication where possible. Network segmentation can also limit exposure by placing administrative interfaces on private networks inaccessible directly from the public internet reducing the attack surface available to remote adversaries exploiting this flaw. Regular security audits focusing on database interaction layers are recommended to identify similar weaknesses across other modules within the application suite before they can be leveraged for broader system compromise.
