DESCRIPTION:
John Leitch has discovered two vulnerabilities in osCSS2, which can
be exploited by malicious people to conduct cross-site scripting
attacks and disclose sensitive information.

1) Input passed via the "feid" parameter to
admin/editeur/tiny_mce/plugins/tinybrowser/upload.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 via the "page_admin" parameter to e.g.
admin/index.php or admin/popup_image.php is not properly verified in
includes/application_top.php before being used to include files. This
can be exploited to include arbitrary files from local resources via
directory traversal attacks and URL-encoded NULL bytes.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerabilities are confirmed in version 2.1.0 RC12. Other
versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
John Leitch, AutoSec Tools.
