Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Secunia reports :

socsam has discovered a vulnerability in WebCalendar, which can be
exploited by malicious people to bypass certain security restrictions
and disclose sensitive information.

Input passed to the 'includedir' parameter isn't properly verified,
before it is used in an 'fopen()' call. This can be exploited to load
an arbitrary setting file from an external web site.

This can further be exploited to disclose the content of arbitrary
files by defining the 'user_inc' variable in a malicious setting file.

Successful exploitation requires that 'register_globals' is enabled.
