SQL Injection in Joomla J-CruisePortal

Executive Summary

Joomla J-CruisePortal version 6.0.4 contains a high-severity SQL injection vulnerability. This flaw allows authenticated attackers to inject malicious SQL code through the 'guest_adult' parameter in POST requests sent to the 'cruises' endpoint.

By exploiting this vulnerability, attackers can execute arbitrary SQL queries on the backend database, which may lead to unauthorized access to sensitive information or manipulation of database records.

Detection Guidance

This vulnerability can be detected by monitoring for suspicious POST requests sent to the 'cruises' endpoint that include the 'guest_adult' parameter with potentially malicious SQL payloads.

A practical detection method is to capture and analyze HTTP POST traffic targeting the '/cruises' endpoint, looking specifically for unusual or crafted SQL code in the 'guest_adult' parameter.

For example, using command-line tools like curl or wget, you can simulate or detect such requests. To test or detect, you might run commands similar to:

• curl -X POST -d "guest_adult=' OR '1'='1" http://[target]/cruises
• tcpdump or Wireshark filters to capture POST requests to the '/cruises' endpoint and inspect the 'guest_adult' parameter for SQL injection patterns.

Mitigation Strategies

Immediate mitigation steps include restricting authenticated user input to the 'guest_adult' parameter by implementing proper input validation and sanitization to prevent SQL injection.

Additionally, applying any available patches or updates from the vendor that address this vulnerability is critical.

If patching is not immediately possible, consider implementing Web Application Firewall (WAF) rules to block malicious payloads targeting the 'guest_adult' parameter in POST requests to the 'cruises' endpoint.

Limiting the privileges of authenticated users to the minimum necessary can also reduce the risk of exploitation.
