Summary0000156: magic_quotes_gpc vs. mysql_escape_string()
DescriptionI see many cases where mysql_escape_string() is applied to $_REQUEST, $_POST or $_GET. As magic_quotes already escaped these strings this may lead to corruption of the userinput.

e.g. in api/ccsr.php

        $username = mysql_escape_string($_REQUEST['username']);
        $password = mysql_escape_string($_REQUEST['password']);

I recommend using something like quote_smart() from php.net

  function quote_smart($value)
  {
     // stripslashes, if necessary
     if (get_magic_quotes_gpc()) {
         $value = stripslashes($value);
     }

     // quote, if not numeric
     if (!is_numeric($value)) {
         $value = "'" . mysql_real_escape_string($value) . "'";
     }

     return $value;
  }


Additionally since PHP 4.3.0 it's recommended to use mysql_real_escape_string().

We need patches and/or source locations, this bug isn't a simple one and feeds back into the requirement to turn off globals...
