Detection Guidance

This vulnerability can be detected by monitoring HTTP GET requests to the Joomla! Component Calendar Planner's events view that include the category_id parameter. Suspicious or malformed SQL code within this parameter may indicate an attempted SQL injection attack.

A practical detection method is to analyze web server logs or use network monitoring tools to filter requests containing the pattern: /index.php/component/calendarplanner/events?searchword=&option=com_calendarplanner&view=events&category_id=[SQL].

Example command using grep on web server logs to find suspicious requests:

• grep "category_id=" /var/log/apache2/access.log

Further inspection of the category_id parameter values for SQL keywords or special characters can help identify exploitation attempts.

Mitigation Strategies

Immediate mitigation steps include updating the Joomla! Component Calendar Planner extension to a version that patches this SQL injection vulnerability, if available.

If an update is not immediately available, restrict access to the vulnerable component by implementing web application firewall (WAF) rules to block or sanitize requests containing suspicious input in the category_id parameter.

Additionally, monitor logs for exploitation attempts and consider disabling or removing the Calendar Planner extension until a fix is applied.
