Bitweaver is an open source content management system. Its speed and  
power are ideal for large-scale community websites and corporate  
applications, but it is simple enough for non-technical small site  
users to set up and administrate.

+--> arbitrary file upload

Code Snippet:

/fisheye/upload.php line#32-45

        $i = 0;
        foreach( array_keys( $_FILES ) as $key ) {
                if( preg_match( '/(^image|pdf)/i', $_FILES[$key]['type'] ) ) {
                        $upImages[$key] = $_FILES[$key];
                        if( !empty( $_REQUEST['imagedata'][$i] ) ) {
                                $upData[$key] = $_REQUEST['imagedata'][$i];
                        } else {
                                $upData[$key] = array();
                        }
		} elseif( !empty( $_FILES[$key]['tmp_name'] ) && !empty(  
$_FILES[$key]['name'] ) ) {
                        $upArchives[$key] = $_FILES[$key];
                }
                $i++;
        }

It's possible to upload arbitrary files with image/gif content-type  
(this can be changed via local proxy or direct content altertion)
also its possible for an attacker to bypass "/storage/.htaccess"  
restriction by uploadding his own .htaccess and control server settings.

Code Snippet:

/wiki/edit.php line#179-195

if( isset( $_REQUEST["suck_url"] ) ) {
        // Suck another page and append to the end of current
        require_once( UTIL_PKG_PATH.'htmlparser/html_parser_inc.php' );
        $suck_url = isset( $_REQUEST["suck_url"] ) ? $_REQUEST["suck_url"] : '';
	$parsehtml = isset( $_REQUEST["parsehtml"] ) ? (  
$_REQUEST["parsehtml"] == 'on' ? 'y' : 'n' ): 'n';
        if( isset( $_REQUEST['do_suck'] ) && strlen( $suck_url ) > 0 ) {
                .
                .
                .
                $sdta = @file_get_contents( $suck_url );
