TITLE:
Maran PHP Forum "name" PHP Code Execution

SECUNIA ADVISORY ID:
SA24968

VERIFY ADVISORY:
http://secunia.com/advisories/24968/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Maran PHP Forum
http://secunia.com/product/14010/

DESCRIPTION:
Dj7xpl has discovered a vulnerability in Maran PHP Forum, which can
be exploited by malicious people to compromise a vulnerable system.

Input passed to the "name" parameter in forum_write.php is not
properly sanitised before it is written to the filename from the
"page" parameter plus an additional ".txt" string. This can be
exploited to execute arbitrary PHP code by including PHP code in
"name" and NULL bytes in "page".

Successful exploitation requires that "magic_quotes_gpc" is disabled.

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

PROVIDED AND/OR DISCOVERED BY:
