DESCRIPTION:
the_Edit0r has discovered a vulnerability in my little weblog, which
can be exploited by malicious people to conduct cross-site scripting
attacks.
Input to the "action" parameter in weblog.php is not properly
sanitised before it is returned to the user when the parameter "show"
has the value "form". This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.
The vulnerability is confirmed in the latest version of the Textfile
edition. Other versions may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
