SQL Injection in Flight Booking System Login Handler

A vulnerability has been found in code-projects Simple Flight Ticket Booking System 1.0. This affects an unknown part of the file checkUser.php of the component POST Parameter Handler. The manipulation of the argument Username leads to sql injection. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

This vulnerability is a remote SQL injection flaw in the Simple Flight Ticket Booking System version 1.0, specifically within the checkUser.php file's POST parameter handler. An attacker can manipulate the Username parameter to inject arbitrary SQL commands, potentially compromising the entire database. This affects any organization or individual deploying this open-source booking system, from small travel agencies to educational institutions using it as a learning platform. With a CVSS score of 7.3 and public exploit disclosure, this represents a significant risk for unauthenticated remote exploitation—attackers can bypass authentication, extract sensitive user data including credentials and payment information, modify booking records, or escalate privileges without any special access requirements.

Casky's 301 matched skills leverage Claude AI's extended reasoning to detect this attack pattern by correlating CWE-74 (Improper Neutralization of Special Elements) and CWE-89 (SQL Injection) against MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance via external sources). Practitioners using Casky would observe detection signals across multiple skill categories: identification of unsanitized user input flows in POST handlers, pattern recognition of SQL metacharacters in parameter values, detection of database error messages leaking schema information, and behavioral anomalies indicating authentication bypass attempts. When a security team investigates findings, they'd see granular mappings showing how malicious payloads like "admin'--" or "' OR '1'='1" progress through the application stack, enabling them to prioritize patching the checkUser.php handler and implementing parameterized queries before exploitation occurs in their environment.
