  <BODY>Builder SQL modification
------------------------------------------------------------------------

SUMMARY

<Body>Builder is a site building engine by Ruslan Communications written
in Java. It allows administrative access via http://site/Admin. All
accounts are stored in database and accessed via SQL. A security
vulnerability in the username and password validation allows user to
modify SQL statement, allowing them to access administrative interface
without a valid username or password.

DETAILS

Exploitation:
 Use login='-- and pass='--

Solution:
Edit _login__jsp.java:

          -- cut --
          java.lang.String _jspParam;
          _jspParam = request.getParameter("username");
          if (_jspParam != null && ! _jspParam.equals("") &&
_checkvalue(_jspParam) )
           Log.setUsername(_jspParam);
          _jspParam = request.getParameter("password");
          if (_jspParam != null && ! _jspParam.equals("") &&
_checkvalue(_jspParam) )
           Log.setPassword(_jspParam);
          --cut--

Add new function called _checkvalue

          public static boolean _checkvalue(java.lang.String _value)
          {
           int count;
           char temp;
           for (count=0;count<_value.length();count++)
           {
            temp=_value.charAt(count);
            if (temp=='\'' ) return false;
           }
            return true;
          }
