DESCRIPTION:
Multiple vulnerabilities have been reported in WebAsyst Shop-Script,
which can be exploited by malicious people to conduct cross-site
scripting and cross-site request forgery attacks.

1) Input passed to the "app" parameter in index.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) The application allows users to perform certain actions via HTTP
requests without performing proper validity checks to verify the
requests. This can be exploited to e.g. alter application data when a
logged-in user visits a specially crafted web page.

3) Input passed to the "orderID_textbox" parameter (when "did" is set
to "21") and input via the URL (when "did" is set to "22") in
SC/html/scripts/index.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.

SOLUTION:
Filter malicious characters or character sequences via a proxy. Do
not browse untrusted web sites or follow untrusted links while being
logged-in to the application.
