CVE-2026-3710 identifies a SQL injection vulnerability in the Simple Flight Ticket Booking System version 1.0 developed by code-projects. The vulnerability resides in the /Adminadd.php script, specifically involving the manipulation of multiple parameters related to flight details such as flightno, airplaneid, departure, dtime, arrival, atime, ec, ep, bc, and bp. Improper input validation or sanitization in these parameters allows an attacker to inject malicious SQL queries into the backend database. This can lead to unauthorized data access, modification, or deletion. The attack vector is remote network access without the need for user interaction, but it requires the attacker to have high privileges, possibly administrative access, to exploit. The vulnerability does not affect system confidentiality, integrity, or availability at a critical level but poses a moderate risk due to the potential for data leakage or manipulation. The vulnerability was publicly disclosed on March 8, 2026, and while no active exploits have been reported, the public disclosure increases the risk of exploitation. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no user interaction, and high privileges required, with low impact on confidentiality, integrity, and availability. The lack of available patches or mitigations from the vendor increases the urgency for organizations to implement compensating controls.

The SQL injection vulnerability in the Simple Flight Ticket Booking System can allow attackers with high privileges to execute arbitrary SQL commands remotely. This can result in unauthorized access to sensitive flight booking data, manipulation of booking records, or disruption of booking operations. While the impact on confidentiality, integrity, and availability is rated low to medium, exploitation could lead to data breaches involving passenger information or operational disruptions in flight booking processes. For organizations relying on this system, especially airlines, travel agencies, or airport management, this vulnerability could undermine customer trust and regulatory compliance. The absence of known exploits in the wild currently limits immediate risk, but public disclosure increases the likelihood of future attacks. The vulnerability's requirement for high privileges reduces the attack surface but does not eliminate risk, especially if internal threat actors or compromised credentials are involved.

Given the absence of official patches, organizations should immediately audit and restrict access to the /Adminadd.php functionality, ensuring only trusted administrators can access it. Implement strict input validation and parameter sanitization on all user-supplied data related to flightno, airplaneid, departure, dtime, arrival, atime, ec, ep, bc, and bp to prevent injection. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting these parameters. Conduct thorough code reviews and refactor the affected code to use parameterized queries or prepared statements to eliminate SQL injection vectors. Monitor database logs for unusual query patterns indicative of injection attempts. Limit database user privileges to the minimum necessary to reduce potential damage from exploitation. Additionally, implement network segmentation to isolate the booking system from other critical infrastructure and enforce multi-factor authentication for administrative access to reduce the risk of privilege abuse.
