CVE-2026-3705: Php

Overview

A high-severity security vulnerability, tracked as CVE-2026-3705, has been identified in the code-projects Simple Flight Ticket Booking System version 1.0. This flaw is a SQL injection vulnerability that could allow an attacker to remotely manipulate the system’s database.

Vulnerability Details

In simple terms, the vulnerability exists in the Adminsearch.php file of the application. Specifically, the flightno parameter is not properly sanitized. This means an attacker can craft malicious input, such as a specially designed flight number, and send it to the server. Because the application does not correctly filter this input, the attacker’s code can “trick” the database into executing unintended commands. This attack can be performed remotely over the internet, and a public exploit is available, significantly increasing the risk of active attacks.

Potential Impact

The impact of this SQL injection is severe. A successful attacker could:

• Steal Sensitive Data: Extract confidential information from the database, including customer details, payment information, booking records, and administrator credentials.
• Modify or Delete Data: Alter flight schedules, bookings, or pricing, or delete critical data entirely, disrupting operations.
• Gain Administrative Control: Potentially compromise the entire application server, leading to a full system breach.

Such a breach could result in significant financial loss, operational downtime, legal liabilities, and severe reputational damage. For context on the real-world consequences of data theft, you can review recent incidents in our breach reports.

Remediation and Mitigation

Immediate action is required to secure affected systems.

Primary Remediation:

1. Patch or Update: Contact the software vendor (code-projects) immediately to obtain a patched version of the Simple Flight Ticket Booking System. If an official patch is not available, consider migrating to a supported and secure alternative.
2. Apply the Fix: Apply the provided update to all instances of the software without delay.

Immediate Mitigations (If Patching is Delayed):

• Network Segmentation: Restrict network access to the booking system’s admin panel. Ensure it is not directly accessible from the public internet; place it behind a VPN or firewall.
• Web Application Firewall (WAF): Deploy a WAF configured with rules to block SQL injection patterns. This can help filter out malicious requests targeting the flightno parameter.
• Input Validation: If you have direct access to the source code, implement strict input validation and parameterized queries for the Adminsearch.php file. However, patching is the definitive solution.
