CWE ID Description
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

CVE-2026-14763 is a Time-based Blind SQL Injection vulnerability affecting the Hotel and Tourism Reservation System PHP version 1.0. It exists in the /admin/tour_reserves.php file, specifically in the 'tour' POST parameter. This parameter does not require authentication for exploitation, allowing an unauthenticated remote attacker to perform SQL injection attacks.

The attacker can exploit this flaw to enumerate the entire database, extract sensitive data such as credentials, and potentially gain full system access.

Impact Analysis

This vulnerability can have severe impacts including unauthorized access to sensitive data stored in the database, such as user credentials. An attacker can remotely exploit the flaw without authentication, potentially gaining full system access.

Such unauthorized access can lead to data breaches, loss of user trust, and compromise of the entire application and its data.

Detection Guidance

The vulnerability is a time-based blind SQL injection in the `tour` POST parameter of the `/ht/admin/tour_reserves.php` file. Detection can be performed by sending specially crafted POST requests to this endpoint and observing response delays indicative of time-based SQL injection.

A common detection method involves sending payloads that cause a delay in the database response if the injection is successful. For example, using curl to send a POST request with a payload that triggers a time delay:

  • curl -X POST -d "tour=1' AND IF(SUBSTRING((SELECT database()),1,1)='a',SLEEP(5),0)-- -" http://target/ht/admin/tour_reserves.php

If the response is delayed by the specified time (e.g., 5 seconds), it indicates the presence of the SQL injection vulnerability.

Mitigation Strategies

The immediate mitigation step is to implement prepared statements with parameterized queries in the affected code to prevent SQL injection.

Additionally, restricting access to the `/ht/admin/tour_reserves.php` page, applying web application firewall (WAF) rules to detect and block SQL injection attempts, and monitoring logs for suspicious activity can help reduce risk until the code is fixed.

Compliance Impact

The vulnerability allows an unauthenticated remote attacker to perform SQL injection attacks, enabling them to extract sensitive data such as credentials and potentially gain full system access.

This exposure of sensitive data can lead to non-compliance with data protection regulations and standards like GDPR and HIPAA, which require the protection of personal and sensitive information against unauthorized access.

Failure to remediate this vulnerability could result in breaches of confidentiality, integrity, and availability of data, thereby violating these compliance requirements.
