Detailed Description The WebCalendar program is vulnerable to an unauthorized access vulnerability in the assistant_edit.php script. WebCalendar is a graphical PHP application used to maintain a calendar for a single user or an intranet group of users. WebCalendar versions prior to 1.0.0 allow a remote attacker to access the assistant_edit.php script directly without proper permissions. A remote attacker could access the assistant_edit.php script directly to change assistants and to display all users in the system even when the 'Public access can view other users' setting has been disabled.
