IMPACT:
Cross Site Scripting, Exposure of sensitive information

http://secunia.com/product/13470/

DESCRIPTION:
Some vulnerabilities and a security issue have been discovered in
Virtual Calendar, which can be exploited by malicious people to gain
knowledge of sensitive information and conduct cross-site scripting
attacks.

1) Incorrect permissions of the "pwd.txt" file can be exploited to
disclose the password of the administrative user.

2) Input passed to the "sho" parameter (if the "m" parameter is not a
value between and including 0 to 13) and to the "t" and "yr"
parameters is not properly sanitised before being returned to the
