TITLE:
CuteNews Cross-Site Scripting and PHP Code Execution Vulnerabilities

SECUNIA ADVISORY ID:
SA33447

VERIFY ADVISORY:
http://secunia.com/advisories/33447/

CRITICAL:
Less critical

IMPACT:
System access, Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
CuteNews 1.x
http://secunia.com/advisories/product/1798/

DESCRIPTION:
athos has discovered some vulnerabilities in CuteNews, which can be
exploited by malicious people to conduct cross-site scripting attacks
and by malicious users to compromise a vulnerable system.

1) Input passed to the "mod" parameter in 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 logged in user's browser
session in the context of an affected site.

2) Input passed to the "add_ip" parameter when blocking IP addresses
is not properly sanitised before being stored in data/ipban.db.php.
This can be exploited to inject and execute arbitrary PHP code.

Successful exploitation of this vulnerability requires administrative
privileges and that support for ".htaccess" files is disabled.

The vulnerabilities are confirmed in version 1.4.6. Other versions
may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
