DESCRIPTION:
Some vulnerabilities have been discovered in 2005-Comments-Script,
which can be exploited by malicious people to conduct cross-site
scripting attacks and script insertion attacks.

1) Input passed to the "id" parameter in kommentar.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 "email" and "url" parameters in kommentar.php
is not properly sanitised before being used. This can be exploited to
insert arbitrary HTML and script code, which is executed in a user's
browser session in context of an affected site when malicious data is
viewed.

The vulnerabilities have been confirmed in the latest version
(2005-03-03). Other versions may also be affected.

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