Auszug aus (Quelle: http://www.derkeiler.com/Mailing-Lis...5-11/0535.html):
a vulnerability exist in globals.php when register_globals is off and allow
remote code inclusion
this a GLOBALS overwrite
in components/com_content/content.html.php
there is the line:
require_once( $GLOBALS['mosConfig_absolute_path'] .
'/includes/HTML_toolbar.php' );
ok
da globals.php:
if (!ini_get('register_globals')) {
while(list($key,$value)=each($_FILES)) $GLOBALS[$key]=$value;
while(list($key,$value)=each($_ENV)) $GLOBALS[$key]=$value;
while(list($key,$value)=each($_GET)) $GLOBALS[$key]=$value;
while(list($key,$value)=each($_POST)) $GLOBALS[$key]=$value;
while(list($key,$value)=each($_COOKIE)) $GLOBALS[$key]=$value;
while(list($key,$value)=each($_SERVER)) $GLOBALS[$key]=$value;
while(list($key,$value)=@each($_SESSION)) $GLOBALS[$key]=$value;
foreach($_FILES as $key => $value){
$GLOBALS[$key]=$_FILES[$key]['tmp_name'];
foreach($value as $ext => $value2){
$key2 = $key . '_' . $ext;
$GLOBALS[$key2] = $value2;
}
}
}
da fake protect in mambo.php:
if (in_array( 'globals', array_keys( array_change_key_case( $_REQUEST,
CASE_LOWER ) ) ) ) {
die( 'Fatal error. Global variable hack attempted.' );
}
if (in_array( '_post', array_keys( array_change_key_case( $_REQUEST,
CASE_LOWER ) ) ) ) {
die( 'Fatal error. Post variable hack attempted.' );
}
Eigentlich gibt'z dazu keine Frage,
höchstens ob save_mode=On schützen würde.
