DESCRIPTION:
benozor77 has discovered a vulnerability in Aweb's Banner Generator,
which can be exploited by malicious people to conduct cross-site
scripting attacks.

Input passed to the "banner" parameter in index.php isn't 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.

The vulnerability has been confirmed in versions 1.21a and 3.0. Other
versions may also be affected.

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