CVE-2024-3347 Overview
A critical SQL injection vulnerability has been identified in SourceCodester Airline Ticket Reservation System version 1.0. The vulnerability exists in the activate_jet_details_form_handler.php file, where improper handling of the jet_id parameter allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries without any authentication, potentially compromising the entire application database.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete sensitive data from the database, including customer information, booking records, and administrative credentials. Complete database compromise is possible without user interaction.

Technical Details for CVE-2024-3347
Vulnerability Analysis
This vulnerability represents a classic SQL injection flaw (CWE-89) affecting the activate_jet_details_form_handler.php file within the Airline Ticket Reservation System. The application fails to properly sanitize user-supplied input in the jet_id parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL code that gets executed by the database server with the same privileges as the application's database user.
The attack can be initiated remotely over the network without requiring any authentication or user interaction, making it highly exploitable. Successful exploitation can lead to complete compromise of data confidentiality, integrity, and availability within the affected database.
Root Cause
The root cause of this vulnerability is the lack of proper input validation and parameterized queries when processing the jet_id parameter. The application directly concatenates user-supplied input into SQL query strings without any sanitization or escaping, allowing attackers to break out of the intended query structure and inject their own SQL commands.
Attack Vector
The attack is executed remotely via network requests to the vulnerable PHP endpoint. An attacker can craft a malicious HTTP request containing SQL injection payloads in the jet_id parameter. Since no authentication is required and no user interaction is needed, the attack can be fully automated.
The vulnerable endpoint activate_jet_details_form_handler.php accepts the jet_id parameter and directly incorporates it into database queries. By manipulating this parameter with SQL metacharacters and commands, attackers can perform operations such as:
- Extracting sensitive data using UNION-based injection
- Bypassing authentication mechanisms
- Modifying or deleting database records
- Potentially achieving remote code execution on the database server
Technical details and proof-of-concept information have been documented in the GitHub vulnerability report and tracked in VulDB #259451.
Detection Methods for CVE-2024-3347
Indicators of Compromise
- HTTP requests to activate_jet_details_form_handler.php containing SQL syntax in the jet_id parameter
- Database error messages or unusual SQL query patterns in application logs
- Unexpected data extraction or modifications in the airline reservation database
- Multiple rapid requests to the vulnerable endpoint from suspicious IP addresses
Detection Strategies
- Monitor web application firewall (WAF) logs for SQL injection patterns targeting the jet_id parameter
- Implement application-level logging to capture and alert on suspicious parameter values containing SQL keywords such as UNION, SELECT, DROP, or single quotes
- Review database query logs for anomalous queries originating from the affected PHP file
- Deploy SentinelOne Singularity to detect and alert on web application attack patterns
Monitoring Recommendations
- Enable verbose logging for all requests to PHP endpoints handling user input
- Configure database activity monitoring to detect unusual query patterns or privilege escalation attempts
- Set up alerts for failed database operations that may indicate injection attempts
- Monitor for data exfiltration patterns from the reservation system database
How to Mitigate CVE-2024-3347
Immediate Actions Required
- Remove or disable the activate_jet_details_form_handler.php file if not essential to operations
- Implement web application firewall rules to block requests containing SQL injection payloads in the jet_id parameter
- Restrict network access to the vulnerable application to trusted IP ranges only
- Conduct a security audit of all PHP files handling user input for similar vulnerabilities
Patch Information
No official vendor patch has been released for this vulnerability. The affected software is a SourceCodester project maintained by Sanchitkmr. Organizations using this system should implement the recommended workarounds or consider migrating to a more secure reservation system. Monitor the VulDB entry for any updates regarding patches or fixes.
Workarounds
- Implement prepared statements or parameterized queries in the vulnerable PHP code to prevent SQL injection
- Add input validation to sanitize the jet_id parameter, ensuring it only accepts expected numeric values
- Deploy a web application firewall with SQL injection detection capabilities in front of the application
- Apply the principle of least privilege to the database user account used by the application to limit potential damage from successful exploitation
# Web server configuration to block suspicious requests (Apache example)
# Add to .htaccess or Apache configuration
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|update|delete|drop|truncate|alter) [NC]
RewriteRule ^activate_jet_details_form_handler\.php - [F,L]
