AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
SQL injection in Simple Flight Ticket Booking System 1.0's checkUser.php allows remote attackers to manipulate database queries.
Vulnerability
A SQL injection vulnerability exists in the checkUser.php file of Code-Projects Simple Flight Ticket Booking System version 1.0. The vulnerability stems from improper handling of user-supplied input in SQL queries, where the Username argument is directly concatenated into SQL statements without proper sanitization or the use of prepared statements [2].
Exploitation
An attacker can exploit this vulnerability remotely by manipulating the Username POST parameter. By sending a crafted payload, an attacker can inject malicious SQL code into the query, potentially leading to unauthorized database access or manipulation. A proof-of-concept demonstrates using time-based SQL injection with a SLEEP() function to confirm the vulnerability [2].
Impact
Successful exploitation of this SQL injection vulnerability can allow an attacker to bypass authentication, read sensitive data from the database, or modify and delete database records. The scope of the compromise depends on the privileges of the database user associated with the application [2].
Mitigation
No specific patched version or release date has been disclosed in the available references. Users are advised to consult the vendor or project maintainers for information on fixes or workarounds. The product is listed as version 1.0 [1, 2].

Vulnerability mechanics
Root cause
"The application directly concatenates user-supplied input into SQL statements without proper sanitization."
Attack vector
An attacker can exploit this vulnerability remotely by sending a crafted POST request to the checkUser.php endpoint. The manipulation targets the 'Username' POST parameter. By injecting SQL metacharacters and commands, an attacker can alter the intended SQL query, leading to SQL injection [ref_id=1]. The provided example demonstrates a time-based SQL injection payload designed to cause a delay if the injection is successful [ref_id=1].
Affected code
The vulnerability resides within the checkUser.php file of the Simple Flight Ticket Booking System v1.0. Specifically, the component responsible for handling POST parameters is affected due to improper handling of user-supplied input within SQL queries [ref_id=1].
What the fix does
The advisory does not specify any patches or provide details on how the vulnerability is fixed. Remediation guidance would typically involve implementing prepared statements or input sanitization to prevent malicious SQL code from being executed.
Preconditions
- inputThe 'Username' POST parameter must be manipulable.
- networkThe attacker must be able to send requests to the vulnerable endpoint.
Reproduction
The vulnerability can be confirmed using time-based SQL injection. Request Example: time curl -X POST "http://host:port/checkUser.php" \ -H "Content-Type: application/x-www-form-urlencoded" \ --data-urlencode "username=admin' AND (SELECT 5572 FROM (SELECT(SLEEP(5)))IoNr)-- wPAH" [ref_id=1]
