Description:
Francesco "aScii" Ongaro has reported some vulnerabilities in WebCalendar, which can be exploited by malicious users to manipulate certain information and conduct SQL injection attacks.
1) Some input passed in "activity_log.php", "admin_handler.php", "edit_template.php", and "export_handler.php" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
2) Input passed to the "id" and "format" parameters in "export_handler.php" isn't properly verified, before it is used to save data files. This can be exploited to overwrite other saved data files.
The vulnerabilities have been reported in version 1.0.1. Other versions may also be affected.
Solution:
Update to version 1.0.2.
