SOFTWARE:
Mini Web Calendar 1.x
http://secunia.com/advisories/product/20451/

DESCRIPTION:
ahmadbady has discovered two vulnerabilities in Mini Web Calendar,
which can be exploited by malicious people to conduct cross-site
scripting attacks or to disclose sensitive information.

1) Input passed via the URL to php/cal_default.php is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

2) Input passed to the "thefile" parameter in php/cal_pdf.php is not
properly verified before being used to read files. This can be
exploited to read arbitrary files from local resources.

The vulnerabilities are confirmed in version 1.2. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified.

Use another product.
