DataLife Engine 9.7 - 'preview.php' PHP Code Injection
Код:
------------------------------------------------------------------
DataLife Engine 9.7 (preview.php) PHP Code Injection Vulnerability
------------------------------------------------------------------

[-] Software Link:

http://dleviet.com/


[-] Affected Version:

9.7 only.


[-] Vulnerability Description:

The vulnerable code is located in the /engine/preview.php script:

246.	$c_list = implode (',', $_REQUEST['catlist']);
247.
248.	if( strpos( $tpl->copy_template, "[catlist=" ) !== false ) {
249.		$tpl->copy_template = preg_replace( "#\\[catlist=(.+?)\\](.*?)\\[/catlist\\]#ies", "check_category('\\1', '\\2', '{$c_list}')", $tpl->copy_template );
250.	}
251.		
252.	if( strpos( $tpl->copy_template, "[not-catlist=" ) !== false ) {
253.		$tpl->copy_template = preg_replace( "#\\[not-catlist=(.+?)\\](.*?)\\[/not-catlist\\]#ies", "check_category('\\1', '\\2', '{$c_list}', false)", $tpl->copy_template );
254.	}

User supplied input passed through the $_REQUEST['catlist'] parameter is not properly
sanitized before being used in a preg_replace() call with the e modifier at lines 249 and 253.
This can be exploited to inject and execute arbitrary PHP code. Successful exploitation of
this vulnerability requires a template which contains a “catlist” (or a “not-catlist”) tag.
