Executive Summary

CVE-2026-2553 is a SQL Injection vulnerability in the tushar-2223 Hotel-Management-System, specifically in the HTTP POST request handler of the file /home.php. The vulnerability arises because user-supplied input parameters such as Name and Email are directly concatenated into an SQL INSERT query without proper input sanitization or the use of prepared statements.

An authenticated attacker can exploit this flaw by injecting arbitrary SQL code through these parameters, enabling unauthorized database interactions. The vulnerability was confirmed using a time-based blind SQL injection technique, where injecting a payload causes a significant delay in server response, proving successful exploitation.

The vulnerability affects the room reservation functionality and can be exploited remotely by an authenticated user.

Detection Guidance

[{'type': 'paragraph', 'content': 'This SQL injection vulnerability can be detected by performing an authenticated test on the room reservation functionality of the tushar-2223 Hotel-Management-System. Specifically, intercept the HTTP POST request to the /home.php endpoint and inject a time-based blind SQL payload into vulnerable parameters such as Name or Email.'}, {'type': 'paragraph', 'content': "For example, you can use a payload like: Name=Alex'+(select*from(select(sleep(10)))a)+' to test for SQL injection. If the server response time increases significantly (e.g., from about 20 ms to over 10,000 ms), it confirms the presence of the vulnerability."}, {'type': 'paragraph', 'content': 'This detection requires logging in as a valid user, navigating to the room reservation feature, and intercepting the POST request with tools such as Burp Suite or curl combined with manual payload injection.'}] [1]

Mitigation Strategies

No known countermeasures or official mitigations have been published by the vendor, who did not respond to the disclosure.

Immediate steps include avoiding use of the affected product or replacing it with an alternative solution, as the vulnerability allows remote authenticated attackers to execute arbitrary SQL commands.

Additionally, restricting access to the affected endpoints, monitoring for suspicious activity, and applying web application firewall (WAF) rules to detect and block SQL injection attempts may help reduce risk until a patch or fix is available.
