Some vulnerabilities have been reported in TotalCalendar, which can be exploited by malicious people to bypass certain security restrictions, to disclose sensitive information, or to conduct SQL injection attacks.
1) A vulnerability is caused due to the application allowing unrestricted access to the admin/manage_users.php script. This can be exploited to change e.g. the password of an existing user via a specially crafted HTTP request to the affected script.
2) Input passed to the "include" parameter in cms_detect.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks.
3) Input passed via the "selectedCal" parameter to rss.php is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
4) Input passed via the "box" parameter to box_display.php is not properly verified before being used to files. This can be exploited to include arbitrary files from local resources via directory traversal attacks.
The vulnerabilities is reported in version 2.4. Other versions may also be affected.
Solution: Restrict access to the "admin/" directory (e.g. via .htaccess). Edit the source code to ensure that input is properly verified.
