DESCRIPTION:
Stefan Schurtz has discovered two vulnerabilities in X3 CMS, which
can be exploited by malicious people to conduct cross-site scripting
attacks.

1) Input passed via the URL to admin/login 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.

Successful exploitation requires that the victim uses a browser that
does not URL-encode the request (e.g. Internet Explorer 6).

2) Input passed via the "username" and "password" POST parameters to
admin/login (when e.g. other POST parameters are not set) 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.

The vulnerabilities are confirmed in version 0.4.3.1-STABLE. Other
versions may also be affected.

SOLUTION:
Vulnerability #2 is fixed within the Bazaar repository. Edit the
source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
Stefan Schurtz, INFOSERVE via Secunia.
