TITLE:
Magtrb MyNews Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA39848

VERIFY ADVISORY:
http://secunia.com/advisories/39848/

DESCRIPTION:
mr_me has discovered some vulnerabilities in Magtrb MyNews, which can
be exploited by malicious people to conduct SQL injection attacks,
cross-site scripting attacks,  and disclose sensitive information.

1) Input passed via the "id" parameter to index.php (when "act" is
set to "article") is not properly sanitised before being used in SQL
queries. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

2) Input passed to the "act" parameter in admin.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 to the "act" parameter in index.php is not properly
verified before being used to include files. This can be exploited to
include arbitrary files from local resources via directory traversal
sequences and URL-encoded NULL bytes.

Successful exploitation of this vulnerability requires that
"magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 1.0. 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:
