Description:
A vulnerability has been reported in WebCalendar, which can be exploited by malicious people to include arbitrary files.

The vulnerability is caused due to an input validation error in "login.php" and "week_ssi.php" making it possible to supply arbitrary paths to files in the variable "$user_inc". This can be exploited by supplying a path to any file using "../../some_file".

Examples:
http://[victim]/login.php?user_inc=../../../etc/passwd
http://[victim]/week_ssi.php?user_inc=../../../etc/passwd
