CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-3735 is a critical SQL injection vulnerability found in version 1.0 of the Simple Flight Ticket Booking System, specifically in the file SearchResultOneway.php.'}, {'type': 'paragraph', 'content': "The vulnerability occurs because the application improperly handles the 'from' parameter, which is user-supplied input, by directly incorporating it into an SQL query without proper validation or sanitization."}, {'type': 'paragraph', 'content': 'This flaw allows attackers to inject malicious SQL code remotely without authentication, enabling them to manipulate the database queries.'}] [1, 2, 3]

Impact Analysis

Exploitation of this vulnerability can lead to unauthorized access to the underlying database.

  • Attackers can read sensitive data stored in the database.
  • They can modify or delete data, compromising data integrity.
  • Full system control and potential service disruption are possible outcomes.

Since the attack requires no authentication and can be launched remotely, it poses a significant security risk.

Detection Guidance

[{'type': 'paragraph', 'content': "This vulnerability can be detected by testing the 'from' POST parameter in the SearchResultOneway.php file for SQL injection. Techniques include Boolean-based blind SQL injection and time-based blind SQL injection using MySQL functions."}, {'type': 'paragraph', 'content': "For example, you can use sqlmap to test the vulnerability by targeting the URL with crafted POST data containing the 'from' parameter."}, {'type': 'list_item', 'content': 'Use sqlmap with a command like: sqlmap -u "http://<target>/flight%20booking/SearchResultOneway.php" --data="from=Beijing" --risk=3 --level=5'}, {'type': 'list_item', 'content': "Test Boolean-based blind SQL injection payloads such as: from=BeiJing') RLIKE (SELECT (CASE WHEN (5041=5041) THEN 0x4265694a696e67 ELSE 0x28 END)) AND ('ClNs'='ClNs"}, {'type': 'list_item', 'content': "Test time-based blind SQL injection payloads such as: from=BeiJing') AND (SELECT 8904 FROM (SELECT(SLEEP(5)))pqAX) AND ('ZnxV'='ZnxV"}] [2]

Mitigation Strategies

[{'type': 'paragraph', 'content': 'Immediate mitigation steps include:'}, {'type': 'list_item', 'content': 'Use prepared statements with parameter binding to separate SQL code from user input, preventing SQL injection.'}, {'type': 'list_item', 'content': 'Implement strict input validation and filtering to ensure inputs conform to expected formats.'}, {'type': 'list_item', 'content': "Limit database user permissions to the minimum necessary, avoiding use of high-privilege accounts like 'root' or 'admin' for application operations."}, {'type': 'list_item', 'content': 'Conduct regular security audits of code and systems to detect and fix vulnerabilities promptly.'}, {'type': 'paragraph', 'content': 'Patching or replacing the vulnerable component is essential to protect system security and data integrity.'}] [2]
