TITLE:

SECUNIA ADVISORY ID:
SA15830

VERIFY ADVISORY:
http://secunia.com/advisories/15830/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
PHP-Fusion 6.x
http://secunia.com/product/5291/
PHP-Fusion 5.x
http://secunia.com/product/4758/
PHP-Fusion 4.x
http://secunia.com/product/3803/

DESCRIPTION:
Easyex has discovered two vulnerabilities in PHP-Fusion, which can be
exploited by malicious people to conduct script insertion attacks or
disclose sensitive information.

1) Input passed to the "news_body", "article_description", and
"article_body" parameters in "submit.php" is not properly sanitised
before being used. This can be exploited to inject arbitrary HTML and
script code, which will be executed in a user's browser session in
context of an affected site when the malicious user data is viewed.

2) Missing access control restrictions on the
"administration/db_backups/" directory makes it possible to retrieve
the database backup files containing users' password hashes.

The vulnerabilities have been confirmed in version 6.00.105. Other
versions may also be affected.

SOLUTION:
1) Edit the source code to ensure that input is properly sanitised.
2) Configure the web server to restrict access to database backup
directory.

PROVIDED AND/OR DISCOVERED BY:
Easyex, Dark Assassins Crew.
