Wuta fuck is dis crap?!
$_COOKIE['ws_auth'] can be exploited by somting like dis:
1:'or/**/1=1/**/limit/**/0,1# (# <- is a comment, dont forget...)
And btw:
$_SESSION['ws_auth'] = $_COOKIE['ws_auth'];
So dont foget to delete teh session...
Bad thing: Only works wit magic_quotes == off
But they got some function:
#_functions.php:74
#function sql_quote($value) {
#
# if( get_magic_quotes_gpc() ) {
# $value = stripslashes( $value );
# }
# if( function_exists( "mysql_real_escape_string" ) ) {
# $value = mysql_real_escape_string( $value );
# }
# else
# {
# $value = addslashes( $value );
# }
# return $value;
#}
And why in the world isnt it used?!
~END~
