DESCRIPTION:
Multiple vulnerabilities have been reported in SimplisCMS, which can
be exploited by malicious people to disclose sensitive information
and conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "download_file" parameter in admin/index.php
(when "action" is set to "do_download" and "section" is set to
"pages") is not properly verified before being used to display files.
This can be exploited to disclose the contents of arbitrary files via
directory traversal attacks.

2) Input passed to the "f" parameter in
admin/application/plugins/scaffold/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.

3) Input passed via the "username" parameter to admin/index.php (when
"action" is set to "signin" and "section" is set to "auth") is not
properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities have been reported in version 1.0.3.0. Other
version may also be affected.

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